Traffic guidance system for use in vehicle, has data processing unit transmitting processed data to application unit over communication unit, where application unit uses data for computing vehicle travel route
摘要
<p>The system has a data processing unit, which correlates the navigation data of an application unit with the travel data and with the road network map data. The speed and the number of motorists and cyclists on the road are determined from the correlated data. The data processing unit transmits the processed data to an application unit over a communication unit. The application unit uses the data for computing the travel route.</p>
