Abstract
A system determines traffic information. The system contains a terminal having a position determination device for determining a position of the vehicle, a storage device for storing reference positions defined by location coordinates, and a processor which works together with the position determining device and the storage device. The processor compares a specific position of the vehicle with stored reference positions to determine whether the vehicle has passed a reference position. A reference position is defined by a safety line extending through the location coordinates thereof. The processor also determines whether the vehicle has traversed a safety line and evaluates the traversing of a determined safety line as the vehicle passes the reference position defined by the safety line. Therefore, the system can determine a position in a simple and reliable manner, including in an inner-city road network.
