Purpose The primary objective of this paper is to propose a framework for specifying and analyzing Intelligent Transport System (ITS) services. Design/methodology/approach Essential service information are identified and stated in a uniform way. A separation into an abstract description, focused on what the service does, and a concrete description, focused on how to perform the service tasks, is made. Findings The proposed a framework has been used for specifying and distinguishing ITS services and for different types on analyses, e.g. service composition/decomposition analyses and architecture analyses. Original/value The usefulness is illustrated by an architecture choice analysis applied on a specific intelligent goods service. Apart from ITS services, the framework has the potential to also apply to other types of information services.
