Embodiment Construction

[0039] A bus signal priority control system based on real-time information interaction, see figure 1 , Which includes the vehicle-mounted terminal 100 installed on the bus, the central signal control subsystem 200 installed in the traffic control command center, and the intersection signal control subsystem 300 installed at the intersection signal, among which,

[0040] The vehicle-mounted terminal 100 includes a vehicle position detection unit 101, a wireless communication unit 102, an information processing unit 103, and a timing information display unit 104. The wireless communication unit 102 is in communication with the network coordination control unit 201 of the central signal control subsystem 200, and the vehicle position is detected The unit 101 locates and determines the latitude and longitude coordinate information of the bus in real time, and the wireless communication unit 102 sends the longitude and latitude coordinate information of the bus to the network coordinati...

Abstract

The invention provides a bus signal priority control system and method based on real-time information interaction which can ensure accurate positioning of vehicles and ensures a bus signal priority control execution effect. A bus signal priority control unit of a center signal control subsystem comprises a GIS information storage module, a positioning information calibration module and a priority control processing module, wherein the GIS information storage module is used for storing GIS maps of city road networks and preset bus passage lines and stores latitude and longitude information of crossing test points with bus priority control applied thereto based on the GIS maps; the positioning information calibration module is used for comparing the received latitude and longitude coordinate information of buses with GIS map data of the city road networks to form calibration latitude and longitude coordinate information of the buses; and the priority control processing module, according to the calibration latitude and longitude coordinate information of the buses, determines whether to execute bus signal priority control on a crossing entrance and generates signal timing dial information for executing the bus signal priority control in real time.

Description

Technical field [0001] The invention relates to the field of intelligent traffic control, in particular to a bus signal priority control system and method based on real-time information interaction. Background technique [0002] With the acceleration of economic and social development and urbanization, problems such as traffic congestion and inconvenience for people in some cities in my country have become increasingly prominent, which have seriously affected urban development and the improvement of people's livelihood. Prioritizing the development of urban public transportation is considered an important and effective way to improve the efficiency of transportation resource utilization and alleviate traffic congestion. The priority control of public traffic signals at intersections improves the efficiency of public traffic by giving priority signals to public traffic vehicles, and is widely recognized and used by traffic practitioners at home and abroad. [0003] The existing Chi...
