NEARCTIS - Role of technologies: Positioning and Communication
Positioning, tracking and communication (PTC) systems are the basic components of cooperative systems, and it is their development in recent years that has in turn made possible the idea of cooperative systems. The ongoing developments of GNSS (Global Navigation Satellite System), of new short range communication systems either between vehicles (V2V) or between the vehicles and the roadside (V2I), lead to new possibilities which have to be taken into account in traffic management. These technologies a primary used for the traffic data collection and the broadcast of information. Secondly we can consider the context of cooperative systems with future use in the verification of traffic strategies, the detection of incidents and the enhancement of driving assistance.
