Method and system for determining dynamic traffic information
First Claim
1. A process for mobile wireless acquisition, in a service center and in a terminal in a vehicle, of dynamic traffic information in a roadway system, the process comprising the steps of:
- determining, in the terminal provided in the vehicle, the vehicle'"'"'s position;
detecting, in the terminal provided in the vehicle, additional traffic-relevant attributes;
relaying information obtained in at least one of the determining step and the detecting step over a mobile wireless telecommunication system to at least one of a group comprising other mobile wireless subscribers and the service center;
compiling long-term traffic information in the vehicle;
controlling the acquisition of traffic information in the vehicle by reaching virtual data acquisition points in the roadway system; and
compiling a historical traffic database in the service center at least in part from the long-term traffic information compiled in the vehicle.

Abstract
A method and system for 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, for example, 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, for example, braking behavior, can be pre-defined by a traffic-control center and transmitted by radio broadcast or mobile telephone system 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.
