Signal lamp control method and device, computer equipment and storage medium

Abstract

The invention relates to a signal lamp control method and device, computer equipment and a storage medium. The method comprises the following steps: if any one of vehicles entering a dilemma area continues to run, acquiring a protection direction and a protection phase in a current signal period according to a preset two-way coordination direction; acquiring a conflict phase of the protection phase; adjusting the signal lamp of the protection phase according to the protection direction; according to the conflict direction, adjusting the signal lamp of the conflict phase; according to the adjusted signal lamp of the conflict phase, whether the signal lamp of the linkage phase needs to be adjusted is judged, and if the signal lamp of the linkage phase needs to be adjusted, the signal lamp of the linkage phase is adjusted; wherein the signal period comprises a plurality of phases, the linkage phases are all phases between the ending moment of the conflict phases and the ending moment of the current signal period, and the protection direction is one of the bidirectional coordination directions. According to the invention, management and control of vehicles in the dilemma area can be realized, and trunk line bidirectional coordination driving efficiency can be considered.

Description

technical field [0001] The present application relates to the traffic field, and in particular to a signal light control method, device, computer equipment and storage medium. Background technique [0002] When the vehicle is driving on the road in the current phase, at the moment when the yellow light of the traffic signal light in the current phase is on, because the current speed is too fast, even if you slow down, you cannot stop safely in front of the stop line of the current road before the red light is on. At the same time, even if the speeding light is seized, the vehicle cannot pass through the intersection at the opposite end when the green light in the next conflicting traffic direction is on, which will lead to a sudden stop and rear-end collision accident or a collision with a passing vehicle in the conflicting direction. . This state of the vehicle is usually called a Dilemma Zone (DZ for short) or a dilemma state. The dilemma is related to the speed of the s...

AI Technical Summary

Problems solved by technology

At present, the more commonly used control method of traffic lights based on the dilemma zone is to extend the duration of the green / yellow light in the direction of the vehicle entering the dilemma zone, so that the vehicle can stop within the stop line or safely pass through the intersection before the red light turns on. , but because it is difficult to judge whether the vehicle will slow down and stop, it may also induce other vehicles that have not entered the dilemma to enter the dilemma during the extended period of the green / yellow light, so it is difficult to extend the duration of the yellow / green light in the direction of the vehicle. reduce the chance of accidents

In addition, if the intersection is an intersection within the coordinated arterial line, this method will also reduce the traffic efficiency of the coordinated arterial line because the yellow / green light in a certain direction lasts too long

[0004] It can be seen that in the existing technology, the signal light control method based on the dilemma state / dilemma area is difficult to meet the needs of coordinating the efficiency and safety of the trunk line at the same time
