    Just in Time och Samlastning: Logistiska strategier för ökad effektivitet, minskade kostnader och förbättrad responsivitet2023Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Abstract

    The purpose of this study is to deepen the knowledge and understanding of the strategies “just in time” and “freight pooling” in logistics management in the food industry. In order to answer the purpose, we had two different research questions. The questions are about what advantages and disadvantages there are with these strategies in the food industry. The study is conducted in a qualitative way where the interviews and observations are used to deepen the knowledge of how an organization in food industries uses the strategies “just in time” and “freight pooling”. The previous science shows that there are some advantages with these strategies but also disantvages that the organization should have in mind and work with so that they do not happen. The study shows that the organization this study was conducted on where very successful in implementing these strategies and they experienced many advantages by using “just in time” and “freight pooling”. The organization this study was conducted on were really cautious with the possible setbacks that the strategies can so they emphasized that they need to work really close with all the involved parties so that they can minimize the risk for the disadvantages to happen. 

    Keywords: just in time, pooling, logistic strategies, transport optimization, food supply chain

    An Agent-based Model for Simulating Travel Patterns of Stroke Patients2021In: DIGITAL 2021: Advances on Societal Digital Transformation / [ed] Wanwan Li; Manuela Popescu, ThinkMind , 2021, p. 11-16Conference paper (Refereed)
    Abstract [en]

    For patients suffering from a stroke, the time until the start of the treatment is a crucial factor with respect to the recovery from this condition. In rural regions, transporting the patient to an adequate hospital typically delays the diagnosis and treatment of a stroke, worsening its prognosis. To reduce the time to treatment, different policies can be applied. This includes, for instance, the use of Mobile Stroke Units (MSUs), which are specialized ambulances that can provide adequate care closer to where the stroke occurred. To simulate and assess different stroke logistics policies, such as the use of MSUs, a major challenge is the realistic modeling of the patients. In this article, we present an approach for generating an artificial population of stroke patients to simulate when and where strokes occur. We apply the model to the region of Skåne, where we investigated the relevance of travel behavior on the spatial distribution of stroke patients.

    Intermodala godstransporter: Varför väljer inte fler företag intermodala järnvägstransporter?2023Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose of this work is to investigate what prevents companies from currently using intermodal rail transportation, where the research questions to be answered are: Do the benefits outweigh the disadvantages of using intermodal rail transportation? What does the future hold for intermodal freight transportation by rail? To address the purpose, we have utilized qualitative methods in the form of interviews, where the interview questions were designed based on semi-structured interviews. The theoretical framework is built using scientific articles and divided into four aspects considered important for customers and their choice of transport mode for the transportation of goods. The empirical material is based on interviews with interviewees working with intermodal rail freight, representing different companies. The empirical material was then compared to the theoretical framework to conduct an analysis, where the material was analyzed using thematic analysis method. The study concluded that sustainability has always been one of the strongest advantages of rail transportation, but it is the disadvantages of rail transportation that have the greatest impact on customers' choices. The disadvantages include time and delivery reliability, and to counteract these disadvantages, investments in rail infrastructure are required. These investments can involve expanding or improving the current rail infrastructure, with the hope that more tracks and a stronger network will minimize the disadvantages, allowing for faster and more efficient transportation. The future of rail transportation is promising if investments and projects are planned correctly. Improvements will lead to an increase in rail freight, but currently, if a company has time-sensitive shipments, the disadvantages outweigh the benefits.

    Collaborative challenges and barriers when planning and implementing Bus Rapid Transit (BRT): Lessons from Swedish BRT projects2023In: Urban, Planning and Transport Research, ISSN 2165-0020, Vol. 11, no 1, article id 2246530Article in journal (Refereed)
    Abstract [en]

    The aim of this paper is to improve the knowledge of collaborative challenges when planning and implementing Bus Rapid Transit (BRT). Collaborative challenges are here understood as the barriers that may arise in BRT planning and implementation as a consequence of several formally independent actors, occasionally with different interests, participating in the planning. The results are based on an analysis of actor interactions in Swedish BRT projects. These projects are analysed in relation to the state of the art in the research field of collaborative approaches. The results show two main and interrelated collaborative challenges. The first category of challenges concerns difficulties for actors in creating a common understanding of what a BRT system is, the second category concerns details of bus priority measures, e.g. busways, priority at intersections, and how to handle and deal with conflicting interests when removing speed bumps or pedestrian and cycle crossings. In terms of policy is in the early stages of the planning processes. This can be generated by working practices and tools that facilitate agreements on how to handle different interests and trade-offs. BRT guidelines adapted to national transport policy, legal and organisational conditions could function as tools in assisting actor dialogue.

    Automatiska lagerlösningar: Olika nivåer av automation och dess inverkan på lagerarbete2021Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Automatic warehousing solutions are a keystone for creating the conditions for streamlining the warehousing processes, primarily to meet consumers' demand on fast and flexible deliveries. Today's technology in warehousing can minimize costs, reduce lead times and increase productivity, which means that automated warehousing solutions are a competitive tool for warehousing operations. This study examines the impact of different degrees of automated warehousing on warehouse work by doing qualitative interviews with warehouse workers working with different types of automated warehouse solutions. The study examines three warehouse solutions with different degrees of automation, where the results show that automatic warehouse solutions mainly generate increased productivity for warehouse workers, but also show that work opportunities in warehouse work, were not affected by automatic warehouse solutions. The results also show different outcomes regarding workload depending on which warehouse solution has been introduced in the business. Automatic warehouse solutions can also improve the ergonomics for warehouse workers by eliminating heavy work with the help of automation, which thereby leads to minor body injuries. Another contributing factor to work-related injuries in a warehouse is that the warehouse workers are in a forklift truck environment, which can be partially eliminated by automatic warehouse solutions. Higher degree of automation means a safer workplace.

    En studie om samordnad varudistribution i Trelleborgs kommun2021Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Urbanization and population growth are two factors that present challenges for the current transport system. Freight transport plays a crucial role in a city's economic life, while at the same time being a contributing factor to a negative environmental impact. At the same time all higher demands, through new legislation, are placed on logistics chains to promote sustainable development. The municipality will therefore be an important player in work towards sustainable development and can, through innovations in the transport systems, contribute to reduced environmental impact. In addition, the municipality can through public procurement, influence and make demands on their suppliers to work towards a sustainable future. By coordinating its distribution to businesses, the municipality can both reduce its environmental impact and promote economic growth.The purpose of this paper is to study coordinated goods distribution in the municipality of Trelleborg, which has only been in operation since November 2020. We have, with the help of interviews from those ultimately responsible for the project and observations from the transshipment terminal, put up the empirical material in the study. In the theoretical frame of reference, we delve into sustainable transport systems and how factors such as infrastructure, public procurement and safety aspects can influence the system. By analyzing the empirical material based on the theoretical frame of reference, we came to the conclusion that it is too early to draw any conclusions about whether the climate impact has decreased and whether the project has been able to promote economic development for the municipality. On the other hand, we can see a positive development as security around the operations in the municipality has increased because transport has decreased. Logistics has also been improved through route optimization and an increased degree of filling in the transports. The municipality has also been able to promote local companies through public procurement, which has led to increased economic growth.

    Intermodala transporter: Undersökning av alternativ lösning för intermodala transporter2021Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Road freight transport is expected to increase significantly in the future if no action is taken. Policymakers are aware that the situation is not sustainable and propose better use of alternative transport, which includes rail transport in intermodal transport. An intermodal system makes it possible to achieve cost savings and higher use of rail transport, as intermodal transport enables the combination of the specific advantages of each mode of transport. This study examines existing problems with the implementation of intermodal transport and what alternative solutions exist that could potentially promote intermodal transport. The study is based on previous research on intermodal transport and empirical collected material from interviewees in the industry as well as relevant data from reports. Problems emerge during transhipment and accessibility on the railway, which has a negative impact on the cost, reliability and speed of transport. It also emerges that several transport relationships and a higher frequency of services are a prerequisite for intermodal transport to produce shorter transport times. The challenge with several transport conditions in Sweden has been that the utilization rate at terminals has been low because there is not a sufficiently high flow between these relationships to create profitability. Train operators believe that a higher speed and a higher load weight would mean increased competitiveness in the market. A higher speed and a higher load weight would also mean greater accessibility and a greater amount of goods per transport. However, the transshipment would still have a negative impact on reliability and flexibility. The study has investigated Flexiwaggon as an alternative intermodal transport solution that could potentially promote intermodal transport. Flexiwaggon is similar to the alternative transport solution RoLa whose vision is to move road transport to the railway. Common to both solutions is to promote the use of intermodal transport. Flexiwaggon shows potential in transhipment due to the flexibility of automated transhipment technology. This means potential saving on terminal, personnel and associated transhipment equipment. What speaks against Flexiwaggon is the investment cost of the wagon solution. Train operators often invest in entire trainsets and would need to replace their existing trainset, reducing train operators' incentives for an alternative intermodal transport solution such as Flexiwaggon as the cost is high.

    How come logistics operators’ ROI are so low despite warehouse operations are very cost efficient?: A business model reconsideration of logistics facilities2020In: The 32nd ANNUAL NOFOMA CONFERENCE: “Operational excellence through logistics resilience" / [ed] Gunnar Stefansson, University of Iceland Press, 2020Conference paper (Refereed)
    Abstract [en]

    Purpose

    Warehouses are of crucial importance to manage increased e-commerce. This study will explore and analyse the warehouse as a relational business model.   

    Design/methodology/approach

    The complex reality of warehouse business development is researched by a qualitative approach analysed in terms of service logic business models. Theoretically, service innovation literature is used to develop understanding of value creation related to e-commerce warehousing.  

    Findings

    Facility location and warehouse management relies of theoretical premises that business is foreseeable. The business model innovation in which real estate actors and logistics actors co-create flexible warehouse solutions is in development. A substantial contribution to logistics and supply chain efficiency and effectiveness is from real estate actors. Logistics actors need logistics facilities to create value for their customers and their competences are related to their network, relations and solution making. Real estate actors’ competences are in developing logistics facilities, which is a way of servitizating service providers. The relationship between real estate actors and logistics providers thereby become of strategic importance for both.  

    Research limitations/implications

    The warehouse as a relational business model opens up for future research by exploring use of and need of new sets of competences.

    Practical implications

    Logistics service providers’ may further develop and broaden their core competences. 

    Original/value

    Business model considerations are of value to e-commerce logistics actors.

    Third-party logistics providers’ strategic development in Sweden: Learning from a crisis2022In: Journal of Transport and Supply Chain Management, ISSN 2310-8789, E-ISSN 1995-5235, Vol. 16, article id a838Article in journal (Refereed)
    Abstract [en]

    Background: The enacted sensemaking of third-party logistics (TPL) providers during the pandemic crisis may present an opportunity to explore their strategic operations.

    Objectives: The aim is to understand the TPL strategic implications related to a crisis and specifically how TPL providers make sense of and respond to crises. The two research questions are as follows: How has the COVID-19 pandemic crisis affected the business operations of TPL providers? What have TPL providers learnt from enacting the crisis, and how has this experience affected their strategic development?

    Method: We conduct an abductive study using combined data from interviews and a targeted archive search. The data are focused on the Swedish context and on a period of the COVID-19 pandemic.

    Results: Three distinct groups of TPL providers have different sense and action processes impacting their business operations. This research shows how an understanding of servitisation is relevant for TPL theory. Finally, we develop the strategic perspective of TPL providers by defining TPL providers as value-cocreating relationships that can help manage the complexities of logistics services.

    Conclusion: This research shows that TPL providers play an important role in crises, as they contribute to solving customer problems. This role appears to be strengthened during crises, but it imposes great demands on TPL providers.

    Contribution: Third-party logistics providers work with their customers during crises. The sensemaking view emphasises the importance of personnel, organisational commitment, capacity and expectations during crises. This is an interplay that requires adaptation to short-term changes in operational processes and adaptability in long-term operations.

    A Bandit-Based Ensemble Framework for Exploration/Exploitation of Diverse Recommendation Components: An Experimental Study within E-Commerce2019In: ACM Transactions on Interactive Intelligent Systems, ISSN 2160-6455, E-ISSN 2160-6463, Vol. 10, no 1, p. 4:1-4:32, article id 4Article in journal (Refereed)
    Abstract [en]

    This work presents an extension of Thompson Sampling bandit policy for orchestrating the collection of base recommendation algorithms for e-commerce. We focus on the problem of item-to-item recommendations, for which multiple behavioral and attribute-based predictors are provided to an ensemble learner. In addition, we detail the construction of a personalized predictor based on k-Nearest Neighbors (kNN), with temporal decay capabilities and event weighting. We show how to adapt Thompson Sampling to realistic situations when neither action availability nor reward stationarity is guaranteed. Furthermore, we investigate the effects of priming the sampler with pre-set parameters of reward probability distributions by utilizing the product catalog and/or event history, when such information is available. We report our experimental results based on the analysis of three real-world e-commerce datasets.

    Evaluating the Efficiency of Bike-Sharing Stations with Data Envelopment Analysis2021In: Sustainability, E-ISSN 2071-1050, Vol. 13, no 2, article id 881Article in journal (Refereed)
    Abstract [en]

    This paper focuses on the efficiency evaluation of bike-sharing systems (BSSs) and develops an approach based on data envelopment analysis (DEA) to support the decisions regarding the performance evaluation of BSS stations. The proposed methodology is applied and tested for the Malmobybike BSS in Malmo, Sweden. This was done by employing spatial analyses and data about the BSS usage trends as well as taking into account transport, land use, and socioeconomic context of the case study. The results of the application demonstrate consistency with the literature and highlight meaningful associations between the station relative efficiency and the urban context. More specifically, the paper provides in-depth knowledge about the preprocessing data, selection of input and output variables, and the underlying analytical approach to be potentially applied to other cases and urban contexts. Overall, the DEA-based methodology presented in this study could assist decision-makers and planners with developing operational strategies for planning and management of BSS stations and networks.

    Analys av transport i en klimatdeklaration: En fallstudie av prefabricerade småhus2021Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The Swedish Parliament have decided on a climate target of zero emissions by 2045. In recent years, the construction and real estate sector have accounted for about one-fifth of the total emissions and the transport sector accounts for a third of the total emissions in Sweden. Climate declarations must be initiated to achieve the climate goals set by the Swedish Parliament. The climate declaration is divided into the product phase and the construction-production phase. Part of the construction-production phase is the transport of resources to the construction site. 

    The problem encountered is the difficulties to obtain exact data for calculating specific transports during a construction project. The purpose of the thesis is to investigate how small house companies with prefabricated elements can design calculations for transport in a climate declaration. In this study, an interview part and a calculation part were carried out to gain an understanding of the challenges. The interviews were conducted on nine respondents with different positions within the transport and environment sector. A climate calculation was calculated on a house model from “VårgårdaHus” who works with prefabricated wall elements. The calculation consisted of three cases. The first case with only generic values during the construction phase. The calculations of the two other cases were conducted with specific values for the transport distances for two fictitious workplaces. 

    The calculations indicate that the climate impact regarding the use of generic data for transport showed an emission of 1296.7 kg CO2e. The specific transport distances resulted in an emission of 693.0 and 495.9 kg CO2e, respectively, during the construction production phase. The results of the interviews show that facilitating climate calculations for transport is possible by improving planning, data collection, collaboration between actors and higher requirements from the organization.

    Significant Route Identification using Daily 24-hour Traffic Flows2020In: 2020 IEEE 23rd International Conference on Intelligent Transportation Systems (ITSC), IEEE, 2020Conference paper (Refereed)
    Abstract [en]

    Traffic flow estimates play a key role in traffic network management and planning of transportation networks. Commonly it is the average daily traffic (ADT) flow for different road segments that constitute the data. This paper shows how an advanced and detailed analysis based on hourly flow measurements over the day can contribute to a deeper understanding of how hourly flows together reflect the vehicles’ routes. The proposed method identifies the shortest travel time paths between all possible origins and destinations in a transportation network, and thereafter it identifies the most significant routes in the network by performing statistical tests. For this purpose, the paper presents a mathematical model, a vehicle simulator based on this model, and a statistical framework that is able to find the most probable underlying routes. The paper contains a real test scenario based on 24-hour traffic flows (hour by hour) to demonstrate the applicability of the method.

    Modelling and Simulating Demand-Responsive Transport2023Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    Public transport is an efficient way to transport large volumes of travellers. However, there are systemic issues that make it hard for conventional public transport to provide efficient service on finer levels, like first- and last-mile problems or low-demand areas. One of the potential solutions that has been getting a lot of attention recently in research and real practice is Demand-Responsive Transport(DRT). The main difference between demand-responsive services and conventional public transport is the need for explicit requests for a trip from the travellers. The service then adapts the routes of the vehicles to satisfy the requests as efficiently as possible. One of the aims of such transport services is to combine the flexibility and accessibility of travel modes like taxis and private cars with the efficiency of buses achieved through ride-sharing.DRT has the potential to improve public transport in, for example, low population density areas or for people with mobility limitations who could request a trip directly to a home door. Historically DRT has been extensively used for special transportation while the recent trend in research and practice explores the possibility of using this service type for the general population.The history of DRT shows a large degree of discontinued trials and services together with low utilisation of vehicles and limited efficiency levels. In practice, this leads to measures restricting the trip destination, times when service is available, or eligibility to use the service at all in case of special transport DRT. Due to the limited use of DRT services, there is little data collected on the efficiency of the service and transport agencies exploring the possibility of introducing this new service type face difficulties in estimating its potential.The main goal of this thesis is to contribute towards developing a decisionsupport method for transport analysts, planners, or decision-makers who want to evaluate the systemic effect of a DRT service such as costs, emissions and effecton society. Decision-makers should be able to evaluate and compare a large variety of DRT design choices like booking time restrictions, vehicle fleet type, target trip quality level, or stop allocation pattern. Using a design science, we develop a simulation approach which is evaluated with two simulation experiments. The simulation experiments themselves provide valuable insight into the potential of DRT services, explore the niche where DRT could provide the most benefits and advocate taking into account the sustainability perspective for a comprehensive comparison of transport modes.

    The findings from the simulation experiments indicate that DRT, even in its extreme forms like fully autonomous shared taxis, does not show the level of efficiency that could result in a revolution in transportation — it is hard to compete inefficiency with conventional public transport in urban zones. However, in scenarios with lower demand levels, it could be more efficient to replace conventional buses with a DRT service when considering costs and emissions. We also show that, when integrated with conventional public transport, DRT could help alleviate the last-mile problem by improving accessibility to long-distance lines. Additionally, if car users are attracted to public transport with the help of DRT, there is a potential to significantly reduce the total level of emissions.

    The simulation results indicate that the proposed simulation method can be applied for the evaluation of DRT. The implementation of trip planning combining DRT and conventional public transport is a major contribution of this thesis. We show that the integration between services may be important for the efficiency of the service, especially when considering the sustainability aspects.

    Finally, this thesis indicates the direction for further research. The proposed simulation approach is suitable for the estimation of the potential of DRT but lacks the ability to make a prediction of the demand for DRT. Integration of a realistic mode choice model and day-to-day simulations are important for making predictions. We also note the complexity of the DRT routing for large-scale problems which prohibits a realistic estimation with simulation and the efficient operation of the service.

    Integrate, not compete! On Potential Integration of Demand Responsive Transport Into Public Transport Network2023Conference paper (Refereed)
    Abstract [en]

    On-demand transport services are often envisioned as stand-alone modes or as a replacement for conventional public transport modes. This leads to a comparison of service efficiencies, or direct competition for passengers between them. The results of this work point to the positive effects of the inclusion of DRT into the public transport network. We simulate a day of operation of a DRT service in a rural area and demonstrate that a DRT system that focuses on increasing accessibility for travellers with poor public transport access can be quite efficient, especially for reducing environmental impact. We show that DRT, while it produces more vehicle kilometres than private cars would inside the DRT operating zone, can help to reduce the vehicle kilometres travelled for long-distance trips. The results of this study indicate the need for a more systemic evaluation of the impact of the new mobility modes.

    Modelling Commuting Activities for the Simulation of Demand Responsive Transport in Rural Areas2020In: Proceedings of the 6th International Conference on Vehicle Technology and Intelligent Transport Systems / [ed] Karsten Berns, Markus Helfert, Oleg Gusikhin, SciTePress, 2020, Vol. 1, p. 89-97Conference paper (Refereed)
    Abstract [en]

    For the provision of efficient and high-quality public transport services in rural areas with a low population density, the introduction of Demand Responsive Transport (DRT) services is reasonable. The optimal design of such services depends on various socio-demographical and environmental factors, which is why the use of simulation is feasible to support planning and decision-making processes. A key challenge for sound simulation results is the generation of realistic demand, i.e., requests for DRT journeys. In this paper, a method for modelling and simulating commuting activities is presented, which is based on statistical real-world data. It is applied to Sjöbo and Tomelilla, two rural municipalities in southern Sweden.

    An Individual-Based Simulation Approach to Demand Responsive Transport2021In: Intelligent Transport Systems, From Research and Development to the Market Uptake, Springer, 2021, p. 72-89Conference paper (Refereed)
    Abstract [en]

    This article demonstrates an approach to the simulation of Demand Responsive Transport (DRT) – a flexible transport mode that typically operates as a combination of taxi and bus modes. Travellers request individual trips and DRT is capable of adjusting its routes or schedule to the needs of travellers. It has been seen as a part of the public transport network, which has the potential to reduce operational costs of public transport services, to provide better service quality for population groups with limited mobility and to improve transport fairness. However, a DRT service needs to be thoroughly planned to target the intended user groups, attract a sufficient demand level and maintain reasonable operational costs. As the demand for DRT is dynamic and heterogeneous, it is difficult to simulate it with a macro approach. To address this problem, we develop and evaluate an individual-based simulation comprising models of traveller behaviour for both supply and demand sides. Travellers choose a trip alternative with a mode choice model and DRT vehicle routing utilises a model of travellers’ mode choice behaviour to optimise routes. This allows capturing supply-side operational costs and demand-side service quality for every individual, what allows for designing a personalised service that can prioritise needy groups of travellers improving transport fairness. By simulating different setups of DRT services, the simulator can be used as a decision support tool.

    Potential Benefits of Demand Responsive Transport in Rural Areas: A Simulation Study in Lolland, Denmark2022In: Sustainability, E-ISSN 2071-1050, Vol. 14, no 6, article id 3252Article in journal (Refereed)
    Abstract [en]

    In rural areas with low demand, demand responsive transport (DRT) can provide an alternative to the regular public transport bus lines, which are expensive to operate in such conditions. With simulation, we explore the potential effects of introducing a DRT service that replaces existing bus lines in Lolland municipality in Denmark, assuming that the existing demand remains unchanged. We set up the DRT service in such a way that its service quality (in terms of waiting time and in-vehicle time) is comparable to the replaced buses. The results show that a DRT service can be more cost efficient than regular buses and can produce significantly less CO2 emissions when the demand level is low. Additionally, we analyse the demand density at which regular buses become more cost efficient and explore how the target service quality of a DRT service can affect operational characteristics. Overall, we argue that DRT could be a more sustainable mode of public transport in low demand areas.

    Förbättrad intern bygglogistik: effektivisering av informationsflöde med digital kalender2023Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background – Construction logistics involves planning and managing of material, equipment and personnel on a construction site. Waste or non-value-added work on the construction site accounts for 30-35% of the costs and can be reduced through efficient material handling. 

    Purpose – The goal was to investigate which delivery activities on a construction site are critical to the schedule and whether Microsoft Bookings is a valid tool to streamlining information flow. 

    Method – The research questions has been answered using qualitative method in a case study and has been complemented by a literature study of theories and previous research in the field. 

    Theory – The theoretical framework is based on digital calendar, communication, handling of materials and Lean Construction. This framework constitutes a reason to use digital tools or describes the positive effects that accompany an implementation.

    Empirical findings – The results of interviews emphasize the importance of planning, involvement, and clarity through visualization for effective delivery management on the construction site. 

    Discussion & Conclusion – A automated booking tool for delivery is in demand and needed as an implementation leads to a reduction of the number of elements that is required for coordinating material deliveries by coordinate relevant information. The final recommendation is to implement Microsoft Bookings as the tool fulfill four out of six identified needs and characteristics. This does not exclude other types of digital calendars to be evaluated, as the goal is to fulfill all the identified needs and characteristics.

    Operational Challenges and Mega Sporting Events Legacy: The Case of BRT Systems in the Global South2020In: Sustainability, E-ISSN 2071-1050, Vol. 12, no 4, article id 1609Article in journal (Refereed)
    Abstract [en]

    This paper examines the bus rapid transit (BRT) legacies of mega sporting events (MSEs) held in the Global South cities of Cape Town and Rio de Janeiro. It discusses the extent to which these transport systems have been operationally sustainable, post-MSE; in other words, their ability to be maintained at a certain rate or level and hence their ability to act as public good as planned and according to specific needs. It argues that in both cities, long-term operational challenges have emerged due to conflictual temporalities between the priorities of the MSE and the mid/long term requirements of a transport system, supplemented by a poor spatial contextualisation of BRT design. These include financial viability, providing a service with appropriate frequency and capacity, integration with other transport systems, and resilience to external shocks such as extreme weather. These findings have key academic and policy implications both by opening further areas of research towards MSEs as a tool to deliver sustainable urban transport, and provides important lessons for future MSE hosts and cities considering BRT.

    Optimal Allocation of Charging Stations for Electric Vehicles Using Probabilistic Route Selection2021In: Computing and informatics, ISSN 1335-9150, Vol. 40, no 2, p. 408-427Article in journal (Refereed)
    Abstract [en]

    Electric vehicles (EVs) are environmentally friendly and are considered to be a promising approach toward a green transportation infrastructure with lower greenhouse gas emissions. However, the limited driving range of EVs demands a strategic allocation of charging facilities, hence providing recharging opportunities that help reduce EV owners' anxiety about their vehicles' range. In this paper, we study a set covering method where self-avoiding walks are utilized to find the most significant locations for charging stations. In the corresponding optimization problem, we derive a lower bound of the number of charging stations in a transportation network to obtain full coverage of the most probable routes. The proposed method is applied to a transportation network of the southern part of Sweden.

    Optimal placement of charging stations for electric vehicles in large-scale transportation networks2019In: Procedia Computer Science, E-ISSN 1877-0509, Vol. 160, p. 77-84Article in journal (Refereed)
    Abstract [en]

    This paper presents a new practical approach to optimally allocate charging stations in large-scale transportation networks for electric vehicles (EVs). The problem is of particular importance to meet the charging demand of the growing fleet of alternative fuel vehicles. Considering the limited driving range of EVs, there is need to supply EV owners with accessible charging stations to reduce their range anxiety. The aim of the Route Node Coverage (RNC) problem, which is considered in the current paper, is to find the minimum number of charging stations, and their locations in order to cover the most probable routes in a transportation network. We propose an iterative approximation technique for RNC, where the associated Integer Problem (IP) is solved by exploiting a probabilistic random walk route selection, and thereby taking advantage of the numerical stability and efficiency of the standard IP software packages. Furthermore, our iterative RNC optimization procedure is both pertinent and straightforward to implement in computer coding and the design technique is therefore highly applicable. The proposed optimization technique is applied on the Sioux-Falls test transportation network, and in a large-scale case study covering the southern part of Sweden, where the focus is on reaching the maximum coverage with a minimum number of charging stations. The results are promising and show that the flexibility, smart route selection, and numerical efficiency of the proposed design technique, can pick out strategic locations for charging stations from thousands of possible locations without numerical difficulties.

    Modeling of road traffic flows in the neighboring regions2022In: Procedia Computer Science, E-ISSN 1877-0509, Vol. 198, p. 43-50Article in journal (Refereed)
    Abstract [en]

    Traffic flows play a very important role in transportation engineering. In particular, link flows are a source of information about the traffic state, which is usually available from the authorities that manage road networks. Link flows are commonly used in both short-term and long-term planning models for operation and maintenance, and to forecast the future needs of transportation infrastructure. In this paper, we propose a model to study how traffic flow in one location can be expected to reflect the traffic flow in a nearby region. The statistical basis of the model is derived from link flows to find estimates of the distribution of traffic flows in junctions. The model is evaluated in a numerical study, which uses real link flow data from a transportation network in southern Sweden. The results indicate that the model may be useful for studying how large departing flows from a node reflect the link flows in a neighboring geographic region.

    A Median-Based Misery Index for Travel Time Reliability2023In: Procedia Computer Science, E-ISSN 1877-0509, Vol. 220, p. 162-169Article in journal (Refereed)
    Abstract [en]

    Travel time reliability is vital for both road agencies and road users. Expected travel time reliability can be used by road agencies to assess the state of a transportation system, and by road users, to schedule their trips. Road network deficiencies, such as insufficient traffic flow capacity of a road segment or poor road design, have a negative impact on the reliability of travel times. Thus, to maintain robust and reliable travel times, the detection of road network deficiencies is vital. By continuously analyzing travel times and using appropriate travel time reliability measurements, it is possible to detect existing deficiencies or deficiencies that may eventually occur unless necessary actions are taken. In many cases, indices and measurements of travel time reliability are related to the distribution of the travel times, specifically the skewness and width of the distribution. The current paper introduces a median-based misery index for travel time reliability. The index is robust and handles travel times that follow a skewed distribution well. The index measures the relative difference between the slow travel speeds and the free-flow travel speed. The index is inspired by the median absolute deviation, and its primary application is to detect routes or road segments with potential road network deficiencies. To demonstrate the applicability of the index, we conducted an empirical case study using real travel speed data from the European route E4 in Sweden. The results from the empirical case study indicate that the index is capable of detecting road segments with slow travel speeds regardless of the travel speed distribution.

    Analys av faktorer som påverkar valav transportör för ett mindre företag2020Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Små och medelstora företag, utgör 90 % av de svenska företagen där transporter är den största kostnadsposten inom deras logistiska verksamhet. Detta gör hantering av transporter för små och medelstora företag till en viktig process. Av den orsaken väljer många företag att outsourca sina transporter för att undvika kostsamma misstag. I den delen, har tredjepartslogistiker (TPL) ett stort nätverk av resurser som i allmänhet leder till att de kan utnyttja resurser eller planera transporter på ett smartare sätt gentemot enskilda partner. Denna studie har sin fokus på att analysera hur Nice Skandinavien AB fattar sina beslut gällande outsourcing av transporter. För att undersöka det, har vi fokuserat på följande faktorer: vilka kriterier och faktorer som är viktiga för Nice Skandinavien AB i samband med outsourcing, transportavvikelser och kvalitetsproblem, single/ double sourcing, kontinuerliga relationer samt hållbarhet. Studien är baserad på observationer, dokumentanalyser och tre semistrukturerade intervjuer med individer som har olika positioner på Nice Skandinavien AB. Företaget är ett säljande småföretag med ett stort utbud av integrerade lösningar för automatisering av grindar, garageportar, solskydd, parkering, trådlöst larm samt hem säkerhetssystem. Det som ligger till grund för vår analys är vår teoretiska referensram och empiri. Genom att utföra observationer och intervjuer samt granska avtalen kom vi fram till att en hög leveransprecision och goda samarbetsrelationer är två viktiga faktorer när det gäller outsourcing av transporter. Det kan resultera i att företaget uppnår effektivitet, produktivitet och minskade transportkostnader samtidigt som de väljer sina leverantörer efter en balans mellan pris, service och kvalitet.

    Decomposing cycling potentials employing the motility framework2021In: Journal of Transport Geography, ISSN 0966-6923, E-ISSN 1873-1236, Vol. 91, article id 102984Article in journal (Refereed)
    Abstract [en]

    The concept of motility, mobility capital, has been put forward to understand mobility from a more holistic perspective through incorporating subjective and objective as well as material and non-material aspects in the examination of individuals? mobility potentials. In this paper, building on a survey study in the two munici-palities of Malmo? and Gothenburg in Sweden, I developed a quantitative operationalization of motility in relation to cycling and employed GIS-based and statistical analyses to identify a set of appropriate indicators to measure the three dimensions of cycling motility namely access, competence, and appropriation. The analyses reveal three operational dimensions underlying the process of appropriating cycling to carry out daily trips. More specifically, individuals? perceptions of the functional and social suitability of cycling and its compatibility with their principles and values seem to be significant for the appropriation of a bike as a daily travel mode. Alto-gether, the findings support that the quantitative operationalization of cycling motility can deepen our under-standing of the factors shaping individuals? cycling potentials and practices, hence offering valuable insights into the development of successful cycling interventions that create material and nonmaterial infrastructure, com-petences, and positive representations necessary for the appropriation of cycling.

    Thinking about Uneven Cycling Motility in a Social Justice Frame2023Manuscript (preprint) (Other academic)
    Abstract [en]

    The positive benefits of cycling cannot be realized in the absence of inclusive policies that improve cycling possibilities for all in society and effectively increase cycling. A more comprehensive understanding of the factors shaping individuals’ potential to cycle and the way the vary across social groups could provide valuable insights to support crafting such policies that could make cycling accessible for more diverse groups in society. Employing the motility framework this study examines the inequalities in cycling potential among individuals living in the municipalities of Gothenburg and Malmö in Sweden. Moreover, it adopts Nancy Fraser’s three-dimensional justice lens to explore the links between social groups’ differences in terms of cycling motility and sources of injustice in cycling practices and policies. The findings indicate that age and income are associated with significant variations in all three dimensions of cycling motility (i.e., access portfolio, competence, and appropriation). Additionally, the significant inequalities observed among the social groups in terms of cycling motility indicators could be traced to broader injustices in society – namely maldistribution, misrecognition, and misrepresentation. The paper argues that justice in cycling motility requires recognizing the diversity of needs and preferences, redistributing cycling-related resources, and including more voices in planning and decisionmaking.

    Inequalities in access to bike-and-ride opportunities: Findings for the city of Malmö2019In: Transportation Research Part A: Policy and Practice, ISSN 0965-8564, E-ISSN 1879-2375, Vol. 130, p. 673-688Article in journal (Refereed)
    Abstract [en]

    Intermodality or combining more than one transport mode during a single trip has been put forward to facilitate a modal shift from private car to more environmentally friendly modes such as public transport, cycling or walking. Bike-and-ride – that is, integrating cycling and public transport in one trip – is an attractive combination, as cycling as an active and clean mode is faster than walking and more affordable and flexible than other alternative modes of transport. Using cycling as a feeder mode to public transport could potentially allow people to reach more opportunities and improve their mobility, and ultimately, their well-being. Therefore, it is relevant to investigate the inequalities in access to bike-and-ride options across population groups.

    In this context, we suggest assessing the inequalities in bicycle access to the main transport hubs of a city by developing a composite indicator based on accessibility measures and the Theil index of inequality. This indicator captures the role of both private and public bikes – part of a Bike Sharing System (BSS) – in accessing the existing public transport system. The novelty of our approach lies in bringing the distributional justice perspective in the accessibility evaluation of transport and analysing the inequalities within and between any arbitrarily defined population groups. Moreover, in addition to travel time by bike, this accessibility measure incorporates a series of bike-related features, such as the typology of bike lanes (separated from or shared with roads), the presence of a BSS in the network, and bike facilities (e.g., parking racks) in transport hubs.

    The proposed methodology is applied to a real case study of the city of Malmö, Sweden, to prove its efficacy and usefulness. In particular, we examine how the level of bicycle access to the major public transport destination (including train stations and regional bus hubs) varies across the population. While considering the contextual properties of the city of Malmö, the inequalities are analysed in relation to spatial dimension and social background of the population, it is possible to extend the proposed analysis by including further features of the population, such as income or gender, and apply the same approach to different contexts.

    Shaping sustainable travel behaviour: Attitude, skills, and access all matter2020In: Transportation Research Part D: Transport and Environment, ISSN 1361-9209, E-ISSN 1879-2340, Vol. 88, article id 102566Article in journal (Refereed)
    Abstract [en]

    Drawing on the conceptualisation of motility as the capacity to be mobile, this paper employs statistical and GIS-based analyses to explore the associations between travel mode choice and mobility-related attitudes, skills and opportunities to access transport modes. The study builds on survey data and spatial data from three urban contexts of Beijing, Gothenburg and Malmo to analyse both individual-level and contextual factors influencing sustainable travel behaviour. The results indicate that despite varying contexts, the three dimensions of attitude, skills and access significantly explain individuals' travel behaviour and their choice to travel by public transport, bicycle or car. Among the studied travel modes, cycling appears to be a competitive mode when the travel distances are within 5 km. In all three urban contexts, individuals who have greater environmental awareness are more likely to travel by public transport or cycling if the physical conditions facilitate using these modes. Good access to public transport is likely to increase the usage of both cycling and public transport and reduce car use. Favourable conditions for cycling within 2 km and 5 km radius can positively encourage people to use a bicycle as a feeder mode for public transport. Overall, our findings demonstrate that for mobility policies to increase individuals' motility in relation to sustainable travel modes and encourage a travel behaviour shift towards using alternatives to cars, planners need to take more holistic approaches and design policies that deal with the three motility dimensions in an integrated manner and avoid focusing on a single dimension in isolation.

    Information flows in Demand Responsive Public Transport: Interactivity, information, and flexibility in a modern ridesharing service2021Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The focus of this thesis is to study what and how information flows can be used to improve Demand responsive transport (DRT) systems by understanding potential users and how they could be willing to participate in DRT to a higher degree. The viewpoint of this thesis tends to lean towards a DRT service of a public transport type. This thesis studies users in relation to what interaction and information they perceive to be needed in dealing with a DRT service and the different pros and cons with various approaches. The study gathers information by performing adapted qualitative interviews with a select number of users between the ages of 20-35. The participants give their views on three DRT scenarios and reflect on DRT in general as a concept presented to them through a tangible mocked-up interactive prototype. 

    The thesis makes several distinct findings. The importance of pricing a DRT service correctly is vital to the users, as several participants in the study relied on pricing for decision-making. It also finds that the usage of zones as nomenclature is confusing to many users. The services must be dependable and punctual to both attract users, keep users, and build trust among the general populace.

    This study shows that DRT services could be a difficult concept to introduce to users. DRT could be introduced as a complement or as an alternative to conventional public transport. An important factor is a well-designed flow of information in the application to keep the user engaged and involved. It is shown that the usability of the application is a cornerstone for a theoretical DRT service to excel. Context is important where DRT and ridesharing would have a higher success rate. Nighttime in urban areas could be a niche market, due to the irregularity, delay, or interruption of regular public transport services at these hours.

    The transport sector is currently undergoing rapid development, which is to a large extent driven by innovation and technological changes initiated by various market actors. At the same time, public transport operations are largely framed by extensive procurement processes and a mature market where a few large companies compete for market share. In Europe, there is tension between rapid innovative development in the sector, on one hand, and stability given by regulation practices shaping procurement processes, on the other. This paper presents results from a study in which opportunities for innovation in procurement processes were examined. The findings are based on public transport authorities' and transport companies’ experiences from tendering bus transport in the three largest cities in Sweden. By using a theoretical perspective of innovation and institutional logics, the paper explains the restrictive role innovation has in procurement processes and discusses the conflicting views transport authorities and transport companies put forward. The paper is of general value since it raises questions related to the complexity of existing tendering regimes and the possibilities of facilitating innovation.

    Kommunerna och kollektivtrafiken: en enkätundersökning om Sveriges kommuners arbete för att stödja kollektivtrafiken2018Report (Other academic)
    Abstract [sv]

    Syftet med denna rapport är att ge en bild av hur Sveriges kommuner arbetar med att främja kollektivtrafiken. Trots att kommunerna i de flesta fall inte har direkt rådighet över kollektivtrafiken påverkar kommunal styrning områden såsom bebyggelseplanering och lokalisering, trafikplanering (ex omfördelning av befintlig vägkapacitet), reglering av biltrafik (ex. parkering, bilfria zoner, m.m.) mobility management och gröna resplaner. Rapporten baseras på en enkätstudie som har riktats till landets samtliga kommuner.

    Resultaten visar både på likheter och skillnader mellan kommunerna avseende målsättningar, definitioner av begrepp och vilken typ av åtgärder och arbetssätt som förekommer. Ett generellt och förväntat mönster är att befolkningsmässigt större och täta kommuner jobbar mer med frågor kring kollektivtrafik, medan frågorna har mindre fokus i mindre och glesare kommuner. Samma, förväntade mönster gäller avseende målbilder och åtgärder för minskad biltrafik; det är vanligare att frågorna är i fokus i mer urbana områden.

    Hur man definierar mål om att öka kollektivtrafiken varierar. Kommunerna jobbar med en bred palett av åtgärder för att främja kollektivtrafiken såsom uppgradering av bytespunkter, ny eller förbättrad infrastruktur för buss-och spårtrafik, reservation av mark för framtida behov och byte av bränsle. Analysen tyder på att det finns ett samband mellan att ha ett mål om ökad kollektivtrafik och att genomföra åtgärder, d.v.s. det är vanligare att kommuner som har ett mål om ökad kollektivtrafik genomför åtgärder för att främja kollektivtrafiken än de kommuner som inte har något mål.

    Det finns inget tydligt samband mellan att ha ett mål om minskning av biltrafiken och att genomföra åtgärder för att minska biltrafiken. Det är vanligare att kommuner genomför åtgärder för att sänka hastigheten än åtgärder såsom att minska antalet parkeringsplatser, eller höjda parkeringsavgifter.

    Förekomsten av tydliga definitioner av begrepp såsom kollektivtrafiknära läge och täthet i landets kommuner varierar. Många kommuner har en definition av kollektivtrafiknära läge (vars innebörd dock kan variera betydligt), medan definitioner av begreppet täthet är betydligt ovanligare. Resultaten från enkätstudien indikerar att här finns potential för vidareutveckling av metoder och arbetssätt kopplade till definitionerna av begreppen. Vissa kommuners arbetssätt borde också kunna ligga till grund för kunskapsöverföring mellan kommuner.

    När det gäller attityd-och beteendepåverkan är det relativt vanligt med vissa typer av åtgärder, såsom kommuninterna resepolicies som prioriterar kollektivtrafik före bil, informationskampanjer och ”prova på” kampanjer. Det är mer ovanligt att man jobbar för att andra aktörer ska införa resepolicies. Även här finns det en potential för utveckling och kunskapsöverföring mellan kommuner.

    Omvandling av svensk färjetrafik: “En fallstudie av hinder och påskyndande faktorer till elektrifiering av bilfärjor”2023Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Sweden has set out to achieve certain climate goals by the year of 2045. These climate goals are more grand than many other of the European Union countries. With this in mind it’s easy to infer that the politicians of Sweden intend Sweden to be in the foreground when it comes to battling climate change. The amount of ferries in scheduled traffic is both numerically and percentually small in comparison. Therefore the authors of this study decided that it would be of interest to research this subject further to be able to understand the reasons behind Sweden not being in the foreground of this matter compared to their climate goals. In order to be able to conduct the study the authors have been in contact with several individuals in different domestic shipping companies as well as a company that offers comprehensive solutions in the maritime field so as to gather information on what they assume is the reason behind the low amount of electrified ferries. The study has a hybrid approach whereby after initially familiarizing them within relevant scientific articles, the collection of empirical data could begin after which the authors further searched for valuable scientific articles on the subject to be able to build a theoretical framework to base their study on. The theoretical framework consists of previous research on the matter and consists solely of peer-reviewed articles. The theoretical framework proves that there are some obstacles relating to the matter of electrifying ferries. The empirical data consists of the interviews conducted with individuals within the aforementioned companies. The authors found that it is not as easy to make the transition to electric ferries as one would think. There is a set of obstacles that the industry has to overcome as well as a lack of administration and funds coming from the state and other institutions.

    Questioning mobility ideals - the value of proximity for residents in socially deprived urban areas in Sweden2021In: Mobilities, ISSN 1745-0101, E-ISSN 1745-011X, Vol. 16, no 5, p. 792-808Article in journal (Refereed)
    Abstract [en]

    Despite discourses of contemporary high-mobility, a life characterised by high mobility is in sharp contrast to many people's experiences and personal preferences. Previous research has shown that mobility and transport opportunities are unevenly distributed in society. The paper explores how young unemployed people and low-skilled care workers in two Swedish urban municipalities prefer to travel less and stay local rather than undergoing time-consuming and expensive public transport trips. The results show that various temporal and spatial restrictions are significant regarding the extent to which public transport can cater for mobility needs, and that transport opportunities are part of an individual's opportunity to be socially included. The results indicate that other policy areas, such as the labour market policy and the public health policy, are equally important for social inclusion.

    On the use of active mobile and stationary devices for detailed traffic data collection: A simulation-based evaluation2020In: International Journal of Traffic and Transportation Management, Vol. 02, no 02, p. 35-42Article in journal (Refereed)
    Abstract [en]

    The process of collecting traffic data is a key component to evaluate the current state of a transportation network and to analyze movements of vehicles. In this paper, we argue that both active stationary and mobile measurement devices should be taken into account for high-quality traffic data with sufficient geographic coverage. Stationary devices are able to collect data over time at certain locations in the network and mobile devices are able to gather data over large geographic regions. Hence, the two types of measurement devices have complementary properties and should be used in conjunction with each other in the data collection process. To evaluate the complementary characteristics of stationary and mobile devices for traffic data collection, we present a traffic simulation model, which we use to study the share of successfully identified vehicles when using both types of devices with varying identification rate. The results from our simulation study, using freight transport in southern Sweden, shows that the share of successfully identified vehicles can be significantly improved by using both stationary and mobile measurement devices.

    On the use of clustering analysis for identification of unsafe places in an urban traffic network2020In: Procedia Computer Science, E-ISSN 1877-0509, Vol. 170, p. 187-194Article in journal (Refereed)
    Abstract [en]

    As an alternative to the car, the bicycle is considered important for obtaining more sustainable urban transport. The bicycle has many positive effects; however, bicyclists are more vulnerable than users of other transport modes, and the number of bicycle related injuries and fatalities are too high. We present a clustering analysis aiming to support the identification of the locations of bicyclists' perceived unsafety in an urban traffic network, so-called bicycle impediments. In particular, we used an iterative k-means clustering approach, which is a contribution of the current paper, and DBSCAN. In contrast to standard k-means clustering, our iterative k-means clustering approach enables to remove outliers from the data set. In our study, we used data collected by bicyclists travelling in the city of Lund, Sweden, where each data point defines a location and time of a bicyclist's perceived unsafety. The results of our study show that 1) clustering is a useful approach in order to support the identification of perceived unsafe locations for bicyclists in an urban traffic network and 2) it might be beneficial to combine different types of clustering to support the identification process.

    How to create efficient public transport systems?: A systematic review of critical problems and approaches for addressing the problems2020In: Transport Policy, ISSN 0967-070X, E-ISSN 1879-310X, Vol. 98, p. 186-196Article in journal (Refereed)
    Abstract [en]

    Creating efficient public transport systems that attract users is a challenging task in contexts where the control of public transport is divided between various actors. Recent research on public transport has therefore seen increasing focus on issues like coordination, collaboration and steering in complex governance settings. However, more is known about what needs to be done than how to implement the necessary changes. This paper presents a systematic literature review with a focus on developing the understanding on how to improve the conditions for public transport. The reviewed articles are analysed for increasing the understanding of the critical challenges in the planning and implementation of measures to increase public transport travel; the working practices for dealing with problems described in the literature; and the advantages and disadvantages of different working practices. Based on the analysis an analytical framework is developed that can be used to study and evaluate working practices for managing critical challenges. The framework consists of three interconnected factors (i) actors, (ii) institutions (laws and rules that govern the interaction of the actors), and (iii) work processes (phases in the interaction between the actors). Drawing on the results of the systematic review a number of key issues for establishing working practices for dealing with the challenges are emphasized for each of the factors.

    Kollektivtrafikorienterad bebyggelseplanering (KOB) i mindre tätorter och på landsbygden: Rekommendationer för policy och planering2022Report (Other (popular science, discussion, etc.))
    Abstract [sv]

    För att få fler människor att välja kollektivtrafiken behöver ny bebyggelse lokaliseras till platser med god kollektivtrafik, till exempel, till stationsnära lägen och genom att förtäta och blanda bostäder, service och grönområden för att ge invånarna närhet till olika aktiviteter. En kollektivtrafikorienterad bebyggelseplanering (KOB) – innebär att man skapar en tätare och mer stadsmässig bebyggelse kring kollektivtrafikens noder och stråk. I mindre tätorter och på landsbygden är förutsättningarna för det annorlunda än i större städer, och KOB måste därför anpassas till dessa förutsättningar. Planeringen av KOBpåverkas därtill av flera offentliga och privata organisationer, och deras samverkan är av central betydelse för att KOB ska kunna förverkligas i mindre tätorter och på landsbygden. I denna rapport beskrivs hur man kan främja KOB i mindre tätorter och på landsbygden i Sverige. Följande fem övergripande rekommendationer syftar till att stimulera KOB på platser med lägre täthet men möjligheter till god kollektivtrafikförsörjning:

    a) Utveckla en regional KOB-strategi och en regionalt anpassad KOB-typologi

    b) Ta fram strategier för kollektivtrafikorienterad fastighetsutveckling i samarbetemellan myndigheter och marknadsaktörer

    c) Utveckla kommunala förtätningsstrategier för kollektivtrafikorienteradbebyggelsed) Utveckla kommunala kollektivtrafikstrategier

    e) Utveckla en väl fungerande samverkan kring KOB

    Decreasing the Share of Travel by Car: Strategies for Implementing ’Push’ or ‘Pull’ Measures in a Traditionally Car-Centric Transport and Land Use Planning2023In: International Journal of Sustainable Transportation, ISSN 1556-8318, E-ISSN 1556-8334, Vol. 17, no 5, p. 446-458Article in journal (Refereed)
    Abstract [en]

    This paper analyzes strategies that can be successfully pursued to implement measures to reduce car traffic in what has traditionally been a very car-centric planning praxis. Analytically, the paper use path dependency theory to provide an understanding of why certain types of measure are not implemented in cities on as widespread a basis as policy objectives may require, and to understand how transport planning path dependence in urban authorities might be changed. Empirically, the analysis builds on a comparative case study of transport and land use planning in Swedish cities. The most effective strategies do not appear to be radical policies leading to fast implementation of goals about sustainable transport, for example by implementing very car restrictive measures, even in the face of resistance from the public and from within the city administration. The results support an approach that from a strategy making perspective can be understood as an institutionalizing process by which internal organizational and external public support for car restrictive and potentially controversial measures are built. Implementation may be achieved by building new institutions within city administrations, where routines and norms gradually change so that car restraint measures gradually become part of the normal way of doing transport planning. This then starts to lock-in certain patterns of travel and make further car restraint measures more feasible and institutionalized as part of a standard menu of measures that cities use, and not something out of the order.

    Context-Aware Travel Support During Unplanned Public Transport Disturbances2023In: Proceedings of the 9th International Conference on Vehicle Technology and Intelligent Transport Systems / [ed] Alexey Vinel, Jeroen Ploeg, Karsten Berns, Oleg Gisikhin, Setúbal, Portugal: SciTePress, 2023, Vol. 1, p. 160-170, article id 19Conference paper (Refereed)
    Abstract [en]

    This paper explores the possibilities and challenges of realizing a context-aware travel planner with bidirectional information exchange between the actor and the traveller during unplanned traffic disturbances. A prototype app is implemented and tested to identify potential benefits. The app uses data from open APIs, and beacons to detect the traveller context (which train or train platform the traveller is currently on). Alternative travel paths are presented to the user, and each alternative is associated with a certainty factor reflecting the reliability of the travel time prognoses. The paper also presents an interview study that investigates PT actors’ views on the potential use for actors and travellers of new information about certainty factors and travellers’ contexts, during unplanned traffic disturbances. The results show that this type of travel planner can be realized and that it enables travellers to find ways to reach their destination, in situations where the public t ravel planner only suggests infeasible travel paths. The value for the traveller of the certainty factors are also illustrated. Additionally, the results show that providing actors with information about traveller context and certainty factors opens up for the possibility of more advanced support for both the PT actor and the traveller.

    Stated opinions and potential travel with DRT – a survey covering three different age groups2024In: Transportation planning and technology (Print), ISSN 0308-1060, E-ISSN 1029-0354, p. 1-28Article in journal (Refereed)
    Abstract [en]

    Previous  research  shows  that  well-grounded  knowledge  of  the intended  travellers  is  essential  for  achieving  successful  DRT services.  However,  there  is  a  lack  of  understanding  of  the potential  travels  in  different  age  groups,  and  the  acceptance  of design  alternatives  that  may  affect  these.  Based  on  surveys conducted  in  Sweden,  this  paper  investigates  these  factors  in  a hypothetical DRT service, in the age groups 6–17, 18–69 and over 70  years.  A  total  of  1241  people  answered  the  questionnaires. The  results  show  that  the  age  groups  have  similar  acceptance regarding  delays  and  departure time  intervals.  Older adults  have lower  acceptance  of  digital  solutions,  and  children  and  older adults  have  stronger  requirements  for  value-added  services. About  85–90%  of  the  respondents  claim  they  would  use  the service,  at  least  occasionally.  The  results  also  show  how  a  DRT system should be configured to allow room for system efficiency gains, while still being accepted by most travellers.

    Artificial intelligence for improving public transport: a mapping study2024In: Public Transport, ISSN 1866-749X, E-ISSN 1613-7159, Vol. 16, no 1, p. 99-158Article in journal (Refereed)
    Abstract [en]

    The objective of this study is to provide a better understanding of the potential of using Artificial Intelligence (AI) to improve Public Transport (PT), by reviewing research literature. The selection process resulted in 87 scientific publications constituting a sample of how AI has been applied to improve PT. The review shows that the primary aims of using AI are to improve the service quality or to better understand traveller behaviour. Train and bus are the dominant modes of transport investigated. Furthermore, AI is mainly used for three tasks; the most frequent one is prediction, followed by an estimation of the current state, and resource allocation, including planning and scheduling. Only two studies concern automation; all the others provide different kinds of decision support for travellers, PT operators, PT planners, or municipalities. Most of the reviewed AI solutions require significant amounts of data related to the travellers and the PT system. Machine learning is the most frequently used AI technology, with some studies applying reasoning or heuristic search techniques. We conclude that there still remains a great potential of using AI to improve PT waiting to be explored, but that there are also some challenges that need to be considered. They are often related to data, e.g., that large datasets of high quality are needed, that substantial resources and time are needed to pre-process the data, or that the data compromise personal privacy. Further research is needed about how to handle these issues efficiently.

    Abstract [en]

    This edited collection brings together feminist research on transport and planning from different epistemologies, with the intention to contribute to a more holistic transport planning practice. With a feminist perspective on transport policy and planning, the volume insists on the political character of transport planning and policy, and challenges gender-blindness in a policy area that impacts the everyday lives of women, men, girls, and boys. The chapters discuss everyday mobility as an embodied and situated activity in both conceptual and theoretical ways and suggest practical tools for change. The contributions of this collection are threefold: integrating gender research and transport planning, combining quantitative and qualitative gender research perspectives and methods, and highlighting the need to acknowledge the politicization of transport planning and transport practice.
