Abstract
In this paper, the performance of short-range vehicle-roadside (beacon) communication systems, which support multiple RTTT (Road Traffic & Transport Telematics) services and applications, is analysed. After introducing general communication requirements of RTTT applications, a short overview about the current status of the Dedicated Short-Range Communications DSRC prENV draft standards developed within CEN TC 278 WG9 is given. Then, the concept of the performance analysis of vehicle-roadside systems based on integrated models of mobility, channel characteristics and communication protocols will be introduced. Simulation results based on an implementation of a high priority interactive service (Automatic Fee Collection) combined with an additional broadcast-oriented service (Dynamic Route Guidance) are analysed in detail (transaction failure rate, used length of the communication zone, interference between different applications, etc.) and optimal choices of system parameters such as antenna configurations are presented. The results show, that DSRC systems are able to provide multiple RTTT services using the same DSRC link to make best use of the available system capacity and to enhance the benefits for potential users.
