Reference ITS Architectures in Europe

This chapter outlines the reference architectures conceived for intelligent transportation systems (ITS) planning and deployment in Europe, their evolution through the inputs provided by major ITS projects and initiatives and some experiences from the authors when facing the definition of ITS architectures through their involvement in research projects such as Cybercars-2 and MoveUs, by following different approaches. In view of the project's ambitious goals, the definition of an architecture supporting the cloud platform operation and the delivery of mobility services envisaged, with a predominant role of ITS, entailed a huge effort. The main objective was to define a comprehensive architecture for the MoveUs cloud-based platform, the specifications of its core facilities and the high- level interfaces between the different platform components. The methodology adopted to define the specifications of this platform integrated insights and approaches from different engineering fields: traffic engineering, data analytics, software architecting and cloud-based computation deployment.
