Regional bus signal priority method based on bus demands

Abstract

The invention discloses a regional bus signal priority method based on bus demands. The method includes the following steps of (1) carrying out region-grade bus priority judgment, and comparing conflict priority requests of current intersections to obtain a bus route i with the toppest priority, (2) carrying out a route-grade bus priority judgment, judging whether the bus route i is in a late state or a normal state, executing a route-grade bus priority if the bus route i is in the late state, and otherwise, executing an intersection-grade bus priority, (3) as for the intersection-grade bus priority, judging whether a priority vehicle at a current intersection is in a late state or a normal state, executing a normal intersection priority mode when the vehicle is in the normal state, and executing the late intersection priority mode when the vehicle is in the late state. By means of the method, on one hand, the probability that multiple bus routes trigger a priority processing conflict problem at an intersection at the same time is avoided, on the other hand, the intersection-grade bus priority and an intelligent selection single-intersection priority mode can be achieved, and the priority effect is maintained during a traffic jam.

Description

technical field [0001] The invention belongs to the technical field of bus signal priority control, and in particular relates to a method for regional bus signal priority based on bus demand. Background technique [0002] The so-called "bus signal priority" is a way to realize "bus priority" in urban traffic. It optimizes the signal control scheme of urban road intersections to achieve the goal of bus vehicles passing through intersections prior to social vehicles. Priority control of bus signals can greatly improve the traffic capacity of urban road buses, indirectly encourage residents to choose bus travel, and is conducive to promoting the development of public transportation. Today, with the increasing pressure of urban traffic, this control method is of great significance for quickly evacuating traffic pressure and relieving traffic congestion. [0003] At present, the mature bus signal priority control method is mainly to ensure that the bus priority phase can maintai...

Problems solved by technology

[0008] In order to solve the problem that the current priority method cannot intelligently handle priority conflicts, and can only rely on manual experience to specify the processing priority, and under the condition of large-scale road congestion, the traditional bus signal priority method is not effective, and provides a bus demand-based The regional bus signal priority method, on the one hand, by setting priority weights for different bus lines, implements regional-level bus priority in the region, avoiding multiple bus lines triggering priority processing conflicts at intersections at the same time, forming a bus line in the area precedence rule
