System and method for achieving multi-priority special vehicle semaphore control based on RFID

Abstract

The invention relates to a system and a method for achieving multi-priority special vehicle semaphore control based on RFID. The system comprises a plurality of RFID receiving ends, information conversion equipment and traffic semaphore controller, wherein the RFID receiving ends are arranged in positions in distance preset by the system from parking lines in the inlet direction at intersections in corresponding distance; the information conversion equipment is used for converting vehicle information received by an RFID receiving end into main node signals which are transmitted to the traffic semaphore controller; the traffic semaphore controller is used for controlling traffic signals according to the main node signals. By adoption of the system and the method for achieving multi-priority special vehicle semaphore control based on RFID, an RFID technique can be combined with a traffic signal control technique, public traffic vehicles and other special vehicles can be controlled and released according to different priorities, the traffic control effect is remarkable, the times that carrier vehicles stop at the intersections are reduced, remarkable benefits can be made, and the system and the method are applicable to large-scale popularization and application.

Description

technical field [0001] The invention relates to the field of intelligent transportation, in particular to the field of traffic signal control, and specifically refers to a system and method for realizing multi-priority special vehicle signal control based on RFID. Background technique [0002] At present, many cities in China are preparing to launch BRT facilities, and the investment is quite huge. Generally, bus lanes and special BRT phases are used to achieve priority release of buses. It is mainly aimed at public transportation systems. However, many special vehicles fail to obtain a good right of priority, which may lead to greater threats to the public safety and lives of many people (such as ambulances, fire engines, etc.). At the same time, for some cities that have completed road construction but hope to realize the priority direction of public transport vehicles, it is necessary to propose a multi-priority special vehicle priority signal control system based on RFID...

AI Technical Summary

Problems solved by technology

[0003] In the Baosteel factory area, there are mixed intersections of trains and vehicles at some intersections, and the train is made into a high-level special vehicle. If it is detected that there is a need for trains to pass, the system will switch to the train phase through a full red transition; if there is no train signal , but there is a problem that special vehicles such as frame vehicles are not given priority, it is necessary to use a preset period of time and adopt different strategies to release general special vehicles according to the intersection traffic
