Verfahren und Einrichtung zur Ermittlung von Dynamischen Verkehrsinformationen

摘要

Described are a method and system for the determination of dynamic traffic information or traffic events. Relevant data from vehicle-mounted terminals are recorded automatically, by remote interrogation or manually and transmitted directly, together with a location identifier, via a wide-coverage mobile-telephone network, e.g. GSM, to other mobile-telephone subscribers and/or a higher level exchange. In the exchange, the incoming data are processed and fed to selected terminals and/or third parties. In addition, the results of interrogation, e.g. braking behaviour, can be pre-defined by a traffic-control centre and transmitted by radio broadcast or mobile telephone to the terminals of road users in a geographically limited area who can then "observe" the flow of traffic directly and immediately report incoming interrogation results by mobile telephone back to the exchange.
