A new architecture for advanced telematics services

摘要

Advances in Information and Communication Technologies have helped spread the use of telematics, together with a fall in price and a rise in reliability of the systems. The application of such technologies to the mobility area can support the growing requirements for efficiency and safety of transportation systems by means of the development of new services and the strengthening of the existing ones, improving the effectiveness of transportation systems.rnTherefore, for a meaningful diffusion of telematics in transportation, a new approach to the Intelligent Transportation Systems (ITS) design and implementation is required, moving away from the pioneering era where each project is developed like a prototype, towards a new one characterized by a wide use of international standards able to guarantee interoperability and expandability amongst the existing systems.rnMuch work has been done and a lot remains in progress for the definition of a shared standard for the ITS architecture.rnThis paper outlines ARTIST, the Italian ITS architecture, and proposes a physical architecture of the next generation for telematics services, investigating its potential application in the info-mobility area.rnThe proposed physical layer for infomobility services is based on a fully decentralized architecture, able to work without a control centre and characterized by high computational power and a very effective communication and multimedia features.rnAll the devices are based on standard technologies, whereas the communication system is based on Wi-Fi standard, exclusively.rnThe proposed architecture has been applied and tested in SITUS-TP, a research project for the public transportation pointed out by the authors at the Campus of the University of Salerno.
