System for determining traffic information
First Claim
1. A system for determining traffic information, the system comprising:
- a terminal carried along in a vehicle, said terminal having;
a position determination facility for determining a vehicle position and a driving direction of the vehicle in a road network;
a memory for storing reference positions defined by location coordinates; and
a processing facility which works together with said position determination facility and said memory, said processing facility comparing a specific position of the vehicle with stored reference positions for determining whether the vehicle has passed one of the reference positions, a reference position is defined by a safety line running through the location coordinates thereof, wherein the safety line is defined by a reference driving direction for vehicles assigned to the reference position of a carriageway and runs at right angles to this, wherein said processing facility being embodied to determine whether the vehicle has traversed the safety line, to compare a driving direction of the vehicle determined with a traversing of a determined safety line with stored reference driving directions and to evaluate the traversing of the determined safety line as the vehicle passes the reference position defined by the safety line, wherein a passing of the reference position is excluded if the safety line was traversed by the vehicle in a driving direction which deviates from the reference driving direction.

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.
