Control system for automatically accomplishing bus priority according to traffic stream change

Abstract

The invention relates to a control system for automatically accomplishing bus priority according to traffic stream change, which comprises a vehicle detecting subsystem, a traffic data predicting subsystem, a vehicle signal processing subsystem, a traffic signal control subsystem and a communication subsystem, wherein the vehicle detecting subsystem is used for detecting the traffic conditions on a common traffic lane and a lane special for the buses within a period of time through corresponding detecting equipment, and counting the numbers of vehicles passing by; the traffic data predicting subsystem is used for predicting the traffic flow data in a next period of time by utilizing the flow data of the current period of time; the vehicle signal processing subsystem is used for generating a specific bus signal priority control policy and a signal timing scheme; the traffic signal control subsystem is used for controlling various signal lights of a crossing according to the control policy; and the communication subsystem is used for transmitting detecting signals to the traffic data predicting subsystem. The control system can effectively relieve the conflicts between the bus priority and common social vehicles and pedestrian pass.

Description

technical field [0001] The invention relates to the field of public transportation, in particular to a control system for automatically completing public vehicle priority according to changes in traffic flow. Background technique [0002] In recent years, with the rapid development of my country's economy and society, the rapid advancement of urbanization, and the rapid expansion of urban population, this has led to a sharp increase in traffic demand brought about by the expansion of urban fringes and suburbanization of residences. At the same time, road traffic Insufficient facility supply, management, technology, and space make the contradiction between urban traffic demand and supply increasingly prominent. [0003] Based on the advantages of large transport volume, small road area per capita, high operating efficiency, energy saving, and low environmental pollution, the General Office of the State Council forwarded the document "About Priority Development of Urban Public ...

AI Technical Summary

Problems solved by technology

[0004] Among the many public transportation methods, opening bus lanes or opening BRT (Bus Rapid Transportation) is a large-capacity transportation method that is cheaper than subways and light rails, but it is inevitable that buses and social The contradiction between ordinary vehicles and pedestrians passing through traffic intersections, especially during peak traffic hours, this contradiction is even more obvious
