TRAFFIC TELEMATICS IN EUROPE--WITH A BLANKET COVERAGE BUT WITHOUT A SPECIAL ROADSIDE INFRASTRUCTURE
Reinhold Mertens · Steps Forward. Intelligent Transport Systems World CongressVERTIS · 1995
IntraGSM is a system to provide traffic telematics services using existing GSM (global system for mobile communications) infrastructure. The core of the system is on trial on the A555 between Cologne and Bonn (Germany). It is the only system based on the concept of virtual charging areas using the Pan European GSM digital cellular technology. All aspects of full road tolling are included in the trial, such as vehicle identification/classification, bill generation and enforcement, and a number of value added services. Some functional features are simulated. The IntraGSM system can be established almost anywhere. It consists of a number of modular components that, together with a GSM network and the global positioning system (GPS), can identify road users and their location, provide services, and charges them appropriate fees for the use of the road and the services. All interfaces are open and utilize standard data communication protocols, including the GSM network. The modularity of the system permits the future integration of other traffic management systems, payment methods, and tolling systems. IntraGSM is open to a variety of traffic applications, which would be provided in the future on a blanket coverage basis to motorists. The technical approach taken by IntraGSM provides a complete separation in time and space of all transactions. This feature allows for the utilization of sophisticated security and authentication measures that are common in the banking community.
