Intersection bus signal priority control system

Abstract

The invention discloses an intersection bus signal priority control system. The intersection bus signal priority control system comprises a bus priority signal generation device connected with a traffic signal controller at an intersection, an RFID reader arranged at a set distance from an intersection stopping line in the vehicle coming direction, and a vehicle electronic label arranged on a front windshield of a vehicle. The intersection bus signal priority control system is characterized in that the RFID reader accurately reads the vehicle electronic label on a bus approaching the intersection, obtains accurate bus registration information and then sends a bus signal priority request and an expected arrival time to the traffic signal controller so as to enable the traffic signal controller to optimize and adjust signal phase times, so that intersection-level signal control provides time priority to buses, and waiting delays of the buses at the intersection are reduced. The intersection bus signal priority control system is adaptable to signal priority control of an urban bus and also adaptable to signal priority control of a high capacity bus such as a BRT, a trolleybus and a tramcar. In addition, the existing traffic signal controller and traffic signal control system do not need to be reconstructed, and the intersection bus signal priority control system has a wide application prospect.

Description

technical field [0001] The invention relates to an intersection bus signal priority control system based on automobile electronic signs, belongs to the technical field of intelligent transportation, and is suitable for the priority control of bus signals at urban intersections. Background technique [0002] In order to alleviate the increasingly prominent urban traffic congestion in my country, change the mode of traffic development in various cities, improve the quality of life of the people, and improve the level of basic public services of the government, the State Council issued the "Guiding Opinions on Prioritizing the Development of Public Transport in Cities" at the end of 2012, proposing "Increase the priority lanes of public transportation, expand the scope of signal priority, and gradually form a network of priority traffic for public transportation." [0003] As one of the main means to solve problems such as urban traffic congestion, the realization of bus signal ...

AI Technical Summary

Problems solved by technology

These methods all need to transform or upgrade the traffic signal controllers at intersections along the line, so it is difficult to popularize and apply them in various cities, and it is difficult to implement them on a large scale
