Title: METHOD OF DESCRIBING AND GENERATING ROAD NETWORKS AND CORRESPONDING ROAD NETWORK
Abstract:
The invention relates to a method for describing and generating road networks for determining traffic information or road traffic data and/or for determining the travelling times on routes or stretches of routes by at least one mobile detector (1). Said mobile detector (1) comprises a position determining device (2) and a device (6) for data communication with a control center (3). The invention also relates to a road network for determining traffic information and/or for determining the travelling time by at least one mobile detector (1), especially a vehicle. According to the inventive method, the road network and/or parts of the road network are substantially described by node (Kp) and/or contour points (Kop).
