Embodiment Construction

[0089] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in conjunction with specific embodiments of the present application and corresponding drawings. Apparently, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0090] A regional road network consists of multiple intersections. When there is vehicle congestion at an intersection in the regional road network, if the accumulated vehicles are not dissipated in time, the queuing vehicles will overflow to the adjacent intersection, causing the green light at the adjacent intersection to fail, which will further ca...

Abstract

The invention provides a traffic signal lamp control method and device, and is used for solving the technical problem of low operation efficiency of a regional road network. The traffic signal lamp control method comprises the following steps: acquiring regional road network information, and identifying intersections in the regional road network; classifying the regional road network to generate a first type of intersections and a second type of intersections; obtaining regional road network information of the first type of intersections and the second type of intersections, and generating a first release instruction through a first timing model; and sending the first release instruction to the traffic signal lamp group of the first type of intersection so as to control the traffic signal lamp group of the first type of intersections to release the traffic flow of the first type of intersections. Compared with the prior art, the traffic signal lamp control method improves the overall operation efficiency of the regional road network.

Description

technical field [0001] The present application relates to the field of traffic technology, in particular to a traffic signal light control method and device. Background technique [0002] A regional road network consists of multiple intersections. When there is vehicle congestion at an intersection in the regional road network, if the accumulated vehicles are not dissipated in time, the queuing vehicles will overflow to the adjacent intersection, causing the green light at the adjacent intersection to fail, which will further cause the spread of congestion and traffic deadlock. Therefore, the primary problem to be solved for the signal optimization and control of congested intersections is how to optimize the easily congested intersections. [0003] Many researchers first decompose the large-scale regional road network into multiple small-scale control sub-areas or sub-road networks, and then perform optimal control on each sub-area to simplify the modeling and solving proc...
