DESCRIZIONE
The invention relates to a system for determining traffic information. Said system comprises a terminal (1) which is carried along in a vehicle (V), said terminal having a position determination device for determining the position (P) of the vehicle (V) in a road network, a storage device for storing reference positions (R) defined by the location coordinates, and a processing device which works together with the position determining device and the storage device. Said processing device is designed to compare a specific position of the vehicle (P) with stored reference positions (R) in order to determine whether the vehicle (V) has passed a reference position (R). According to the invention, a reference position (R) is defined by a safety line (L) extending through the location coordinates thereof, said processing device is designed to determine whether the vehicle (V) has traversed a safety line (L) and to evaluate the traversing of a determined safety line as the vehicle passes the reference position (R) defined by the safety line (L). As a result, a system which can determine a position in a simple and reliable manner, also in an inner-city road network, is provided.
