Specific role of telecommunications in intelligent transport systems

Abstract

Intelligent Transport Systems solutions typically require selectable level of telecommunications services quality with usually widely spread area coverage. ITS Telecommunications service parameters were re-defined as performance indicators which are tightly linked with the ITS service performance quantification. Wireless data services with reasonable coverage are offered by public wireless mobile services providers, however, mostly no relevant service performance indicators are guaranteed. ITS requirements can be, however, cost-effectively resolved in case the different public and private services are effectively combined. Such solution requires implementation of the flexible system architecture supported by the efficient decision processes. Additionally "Car to Infrastructure" and "Car to Car" communication interconnected with the vehicle on board data network based on the CAN (Controlled Area Network) bus significantly increase potential of the intruders attacks so that the integration of the relevant telecommunications security treatment has been understood as one of critical topics of the ITS telecommunications solution, as well.
