FIELD: procedure of traffic control of vehicles.
SUBSTANCE: the method consists in forming of the sequence of the junction and chord of the terminal on the basis of data of the route search, selection of the terminal junction and chord separation by comparison of the sequence of the junction and chord with the terminal map, reproduction of the data on route control on a complicated roads crossing with the use of the selected terminal junction and chord separation, coordination with the map and tracing of the route at driving on the basis of the reproduced data and submitting of the information on control of the traced route to the user. The vehicle navigation instrument for route control on a complicated roads crossing includes a means for forming of the sequence of the junction and chord of the terminal by comparison of the sequence and of the junction and chord with the terminal map, the means for reproduction of the data on route control on a complicated roads crossing with the use of the selected junction and chord, the means for coordination with the map and tracing of the route at driving on the basis of the reproduced data and submitting of the information on control of the traced route to the user. The vehicle navigation system includes a server for transmission of the required route data from the remote source of geographic information and information on road traffic, the means for obtaining of the required route data from the server, the means for obtaining of information on the present location of the vehicle from the GPS satellite, means for selection of information on vehicle driving with the use of the obtained information on location of the vehicle, means for memorizing and storage of the geographic information, means of route search for search of the geographic information stored in the memorizing means, and the control means for reproduction of the data on route control on a complicated roads crossing with the use of the route data obtained from the server and means of the route search, for realization and means of the route search, for realization of route control and submitting of information on route.
EFFECT: enhanced precision in route control by reconfiguration of the presentation of the complicated roads crossing that cannot be represented by one junction on a digital navigation map.
