Abstract (en)
[origin: EP0880120A2] The method involves using spot check vehicles and predefining one or more position determination resolution criteria. Automatic position measurement is performed by each spot check vehicle when a trigger criterion is fulfilled, whereupon related traffic situation data are detected and signalled. A traffic situation signalling process is performed when a measured travel time and/or an actual position deviate from an anticipated travel time and/or position by more than a defined amount.
