A public transport pre-broadcasting system based on A-GPS and 3G network is composed of a public transport operation center server, car pre-broadcast terminals and station display boards, wherein, the public transport operation center server is provided with a public transport pre-processing module, an interface information processing module, a multi-source heterogeneous traffic data-processing module, a road and public transport line information module, a statistical analysis and decision support module, a system parameters and historical traffic information database and a terminal management module; the car pre-broadcast terminal is provided with a 3G communication module, an A-GPS positioning module, a public transport pre-broadcast software and a display screen; the station display board is provided with a 3G network communication module, a public transport pre-broadcast program and a display screen. The car pre-broadcast terminals and station display boards are connected to the public transport operation center server through a bidirectional information transmission channel established by the 3G network. The public transport operation center server completes the traffic congestion determination, traffic flow forecasts, estimates of bus travel time, bus speed estimates, and calculation of map-matching.
Description
Technical field: [0001] The present invention relates to the field of physics, in particular to communication technology, in particular to broadcasting of urban public transport information, in particular to a public transport forecast broadcasting system based on A-GPS and 3G networks. Background technique: [0002] Urban development has brought about a rapid increase in the population and the number of motor vehicles, which in turn leads to the deterioration of traffic conditions and environmental pollution. Increasing public transportation can reduce the travel of private cars, improve urban road congestion and reduce environmental pollution. But at present, only a small amount of bus lines provide the pre-time broadcast service at the starting station, and at all the remaining stations, the pre-time broadcast cannot be done; waiting passengers cannot determine the time they need to wait. And the existing pre-time broadcast service only provides the station reporting ser...
