Control method and system for intersection signal timing guaranteeing priority of buses

Abstract

The invention relates to a control method and a system for intersection signal timing guaranteeing the priority of buses. The system adopts an ultrahigh frequency RFID (Radio Frequency Identification) technique to achieve the remote recognition, acquisition and control of information of an onboard unit; and adjusting an intersection signal timing scheme through an optimization algorithm by collecting the information of buses in all direction of an intersection, so as to provide control of passing priority for buses. The control method solves the bus priority mode on common urban roads, and realizes the bus passing priority on the basis of maximizing the overall operation efficiency of vehicles at the intersection, so as to improve the operation efficiency of buses. In addition, the control method is low in cost and convenient to implement and becomes effective fast, and achieves the win-win of the bus priority and the overall operation efficiency of the intersection, so as to reduce delays of buses at urban intersections and ensure the punctuality of buses.

Description

technical field [0001] The invention relates to a public transportation priority passing method and equipment, in particular to an intersection signal timing control method and system for ensuring public transportation priority. Background technique [0002] "Public transportation priority" refers to the priority of public transportation, which means that in urban development and planning, the construction and management of public transportation are given priority, and support in terms of policies, funds, and technologies is given to enable them to use smooth roads. , good vehicle conditions, and dense vertical and horizontal online websites provide more, better, and faster services for the public to travel. Giving priority to public transport means giving priority to the common people, and developing public transport means developing people's livelihood. Based on the national conditions of my country's dense population and land shortage, giving priority to the development ...

AI Technical Summary

Problems solved by technology

This kind of bus priority mode belongs to the "space priority" mode. To open up bus lanes, it is not easy to realize on ordinary roads in small and medium-sized cities, and there are certain difficulties. It is not suitable for bus priority on ordinary urban roads.

Many large cities in my country have opened bus lanes, and some bus lines have achieved remarkable results, but the effect on the entire city's bus system is not ideal.

The reason is that apart from the lack of systematic and effective bus lane planning, the main reason is that bus vehicles cannot have priority at intersections

The delay of public transport vehicles at the intersection is much greater than the delay on the road section. Therefore, it is difficult to achieve real bus priority if there is no implementation of bus priority at intersections.
