Intersection signal priority system and method for intelligent rail train

Abstract

The invention discloses an intersection signal priority system and method for intelligent rail trains, which solves the problem of priority passing at intersections of intelligent rail trains, and at the same time satisfies various priority requirements after the lines are networked. The technical solution is: the present invention can accurately determine the priority request timing by using the complete operating line database set in the vehicle-mounted host computer, and avoid unnecessary priority requests. When the vehicle is abnormal, the vehicle-ground short-range communication is abnormal, and the signal priority controller at the intersection is abnormal, the smart rail train operation platform can apply for priority to the road traffic signal control platform to ensure the operation efficiency of the smart rail train. Moreover, the smart rail train operation platform can send information such as the smart rail train operation timetable and train passenger capacity to the road traffic signal control platform, and the road traffic signal control platform can realize the priority strategy at the road network level.

Description

technical field [0001] The invention relates to an urban public traffic management and control technology, in particular to an intersection signal priority system and method for smart rail trains. Background technique [0002] As the problem of urban traffic congestion becomes increasingly prominent, a variety of public transportation solutions have been proposed, including subways, BRTs, light rails, smart rails, etc. The intelligent rail train is a brand-new means of transportation developed by CRRC Zhuzhou Electric Locomotive Research Institute Co., Ltd., with a design maximum speed of 70 kilometers per hour. It adopts high-speed rail flexible marshalling and uses the "virtual track following control" technology to run on the established "virtual trajectory". Light rail, subway and other rail trains have the characteristics of zero emission and no pollution, and support multiple power supply methods. The smart rail express system with smart rail trains as the core vehicl...

AI Technical Summary

Problems solved by technology

[0003] Although the existing technical solutions have proposed a priority solution for public transport vehicles at intersections, vehicles only passively give priority requests, and the level of intelligence is not high, especially for congested intersections. Road traffic signal control The system still needs to make judgments on priority requests, resulting in unnecessary waste of resources

At the same time, the operation platform of public transportation is not the same platform as the road traffic signal control platform, and the related solutions do not involve platform-level interconnection. When public transportation lines are networked, they do not have good scalability
