Vehicle dynamic navigation service system based on A-GPS and 3G network

Abstract

The invention relates to a vehicle dynamic navigation service system based on A-GPS and 3G network, which consists of a dynamic navigation service platform and a dynamic navigation terminal. The dynamic navigation service platform, the 3G network, the A-GPS positioning platform and the dynamic navigation terminal are interconnected to eachother, and perform navigation calculation utilizing the real time traffic information from traffic information center; the navigation result can be fed back to the traffic control center for optimizing the traffic control; the navigation service platform itself integrates the capabilities of dynamic navigation calculating, road geographic information processing, multi-source isomeric real time road condition information processing, navigation data statistics analyzing and policy making supporting, user managing and interface information processing; the dynamic navigation calculating process comprises track jam judgment, traffic flow prediction, dynamic path program and traffic Induction, travel time estimation and map-matching; and the dynamic navigation terminal supports 3G honeycomb communication, A-GPS positioning, memory, dynamic navigation client software and man-machine interface.

Description

Technical field: [0001] The present invention relates to the field of physics, in particular to communication technology, in particular to 3G network-based auxiliary A-GPS positioning, dynamic navigation technology of urban road geographic information, and specifically to a vehicle dynamic navigation service system based on A-GPS and 3G network . Background technique: [0002] Urban development has brought about a rapid increase in population and the number of motor vehicles, which in turn has led to the deterioration of traffic conditions. Traffic congestion can lead to time loss, energy consumption, traffic accidents and environmental problems. Vehicle navigation is an effective method to solve driving efficiency and reduce traffic congestion. At present, vehicle navigation is realized in a static way, that is, through the autonomous GPS positioning of the vehicle navigation terminal, and then combined with the electronic map stored in the terminal, static navigation is ...
