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 bu

Embodiment 1

[0102] Embodiment 1: A work flow of a timing control method for ensuring bus priority

[0103] Such as image 3 As shown, the workflow includes the following steps:

[0104] Step S301, detect that there is a bus arriving, execute step S302;

[0105] In this step, the UHF RFID reader can be installed on the road or beside the road, and the corresponding vehicle-mounted electronic tag can be installed on the bus, so as to realize the real-time detection of the arrival of the bus, and enter the bus immediately after the bus is detected. Priority control process, the phase at which the bus arrives is the bus priority phase;

[0106] Step S302, judging whether the current bus phase is a green light, if so, execute step S303, otherwise execute step S310;

[0107] This step is to judge the state of the current signal light of the phase of the bus when the bus passes through the UHF RFID reader at the crossing;

[0108] Step S303, judging whether the remaining time of the green li...

Embodiment 2

[0129] Example 2: A workflow in which multiple phases detect the arrival of a bus

[0130] Such as Figure 4 As shown, its workflow includes the following steps:

[0131] Step S401, judging whether there is an extension request for the current green light phase, if yes, execute step S402, otherwise execute step S403;

[0132] In this step, regardless of whether there are buses arriving in other phases, it is necessary to first determine whether there are buses in the current green light phase and need to extend the green light to pass through the intersection. This is to give priority to ensuring the passage of buses in the current green light phase;

[0133] Step S402, enter the step of extending the green light, and then execute step S403;

[0134] Step S403, count the number of buses detected in each red light phase, and then execute step S404;

[0135] In this step, the object of quantity statistics is the bus detected by this phase during the period from the last green...

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 ...
