Abstract (en)

[origin: EP0644518A2] In a mobile system of the RTI type, that is to say a system of short-range communication, between a vehicle and the roadside, beacons or radio beacons are utilized. Information on traffic, for example vehicle traffic, is exchanged between the said beacons and the mobile units when the latter pass respective beacons. At least some of the beacons of the mobile system (1) are of the virtual type (VB). This means that positions (P) which represent the said virtual beacons (VB) are specified in the system, preferably in centrally placed elements (VB'). An alternative medium (2) cooperates in order to access data between a respective mobile unit (M2) and a respective virtual beacon (VB). <IMAGE>
