Tram Signal Priority Method for Offline Coordination at Multiple Intersections

Abstract

The invention discloses a multi-intersection offline coordination tramcar signal priority method, which comprises the steps of: S1, dividing crossings along a route into a plurality of coordination intervals according to road characteristics, social traffic volume and station settings factors, so that the whole course includes a plurality of coordination control schemes; S2, making the coordination control schemes adapt to tramcar operating characteristics offline, wherein each coordination control scheme includes compilation of a tramcar operation diagram according to characteristics such as departure intervals, operating speed and station dwell time of a tramcar, and design of a control diagram of a coordination signal control scheme according to characteristics such as operating speed of social vehicles and intersection intervals; S3, and fitting the tramcar operation diagram with the control diagram of the coordination signal control scheme obtained in the step S2. The multi-intersection offline coordination tramcar signal priority method enables the tramcar to obtain signal priority when passing plane intersections and can pass through multiple intersections continuously without a stop, can balance passing time resource benefits of the tramcar and background social traffic, and increases operation efficiency of regional traffic.

Description

technical field [0001] The invention relates to the technical field of transportation, in particular to a tram signal priority method for off-line coordination of multiple intersections. Background technique [0002] As a medium-capacity public transportation, trams need to obtain signal priority when passing through intersections. The current tram signal priority is mainly based on single-point signal priority. When the tram is about to arrive at the intersection, it sends a request to the road traffic signal system through detection and communication means, and makes adjustments at the current intersection. Cut off the red light, insert the phase and other methods to make the tram pass. [0003] The outstanding shortcomings of the current situation are: [0004] 1) Great interference to social traffic, occupying time resources in conflicting directions, and easily causing congestion in other directions. [0005] 2) It is easy to break the original green wave and line co...

AI Technical Summary

Problems solved by technology

[0004] 1) Great interference to social traffic, occupying time resources in conflicting directions, and easily causing congestion in other directions

[0005] 2) It is easy to break the original green wave and line coordination, resulting in a decline in the efficiency of social traffic along the line and even in the region

[0006] 3) The effect on the whole line of trams may not be the best, because when you arrive at an intersection and request and process it once, regardless of the subsequent intersection, it may lead to smooth passage at the first intersection, but the follow-up will be blocked
