Coordinated control method and system for intersection of multi-line rail vehicles at intersection

Abstract

The invention provides a coordinated control method and a coordinated control system for intersection of multi-line rail vehicles at an intersection. The coordinated control method comprises the stepsof: (1) sending out first priority request information and road entering information of a rail vehicle at a set position at the upstream of each entrance lane when the rail vehicle passes; (2) calculating travel time delay of the rail vehicle; (3) assigning a priority strategy to the rail vehicle, and generating second priority request information of the rail vehicle; (4) classifying the second priority request information generated in a certain period of time according to the entrance lanes to which the second priority request information belongs, comparing the second priority request information of first vehicles of the entrance lanes, and combining all the second priority request information of the entrance lanes having the same priority benefit to obtain a priority request set; (5) and calculating the overall priority benefit of the priority request sets, and executing priority requests of all the first vehicles in the priority request set with the highest overall priority benefit. The coordinated control method and the coordinated control system can greatly improve the passing efficiency of the rail vehicles at the hub intersection.

Description

technical field [0001] The invention belongs to the technical field of traffic signal control, and relates to a coordinated control technology, in particular to a coordinated control technology for the intersection of multi-line rail vehicles at an intersection. Background technique [0002] With the rapid development of urbanization in my country, the scale of cities in my country is constantly expanding, the number of motor vehicles is increasing, and the frequency of people's travel is increasing, which makes the problem of urban traffic congestion more and more serious. Vigorously developing urban public transport is an important measure to alleviate traffic congestion. As a new urban public transportation mode, the modern tram system has the characteristics of moderate traffic volume, high speed, environmental protection, flexibility, comfort and novelty, and low construction cost, and has been adopted by many large cities around the world. At the same time, in order t...

AI Technical Summary

Problems solved by technology

This method only considers the priority conflicts of two tram lines, and lacks the spatio-temporal logic analysis of the tram route arrangement, and cannot adapt to more complex line environments; The comparison of the running status of trams did not reduce traffic delays for late vehicles, and also ignored the stability of the line where early vehicles were located, and did not improve the service level of the tram system.
