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

Abstract

The present application relates to a signal light control method, device, computer equipment and storage medium. The method includes: if any of the vehicles entering the dilemma area continues to drive, obtaining the protection direction and the protection phase in the current signal cycle according to the preset two-way coordination direction; obtaining the conflict phase of the protection phase; according to the protection direction, Adjust the signal light of the protection phase; adjust the signal light of the conflicting phase according to the conflict direction; according to the adjusted signal light of the conflicting phase, judge whether the signal light of the linkage phase needs to be adjusted, if the signal light of the linkage phase needs to be adjusted, adjust the signal light of the linkage phase; , the signal cycle includes multiple phases, the linkage phase is all phases between the end time of the conflicting phase and the end time of the current signal cycle, and the protection direction is one of the two-way coordination directions. The application can realize the management and control of vehicles in the dilemma area, and can also take into account the two-way coordinated driving efficiency of the trunk line.

Description

technical field [0001] The present application relates to the field of traffic, 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 of the current phase, at the moment when the yellow light of the traffic signal light of the current phase turns on, because the current speed is too fast, even if the vehicle slows down, it cannot safely stop at the stop line of the current road before the red light turns on. At the same time, even if the vehicle is speeding and grabbing the light, the vehicle cannot pass the opposite intersection when the green light in the next conflicting traffic flow direction is on, which will lead to an emergency stop and rear-end collision near the intersection or a collision accident with the released vehicle in the conflicting direction. . This state of the vehicle is often referred to as the Dilemma Zone (DZ) or the dilemma state. Th...

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
