Traffic light time regulation and control method applied to two-way multi-lane pedestrian crossing

Abstract

The invention belongs to the technical field of intelligent traffic, and discloses a traffic light time regulation and control method applied to a two-way multi-lane pedestrian crossing. Based on a video image recognition technology, the number of waiting people at the crossing is determined by recognizing real-time video images collected by monitoring equipment of the crossing, and a traffic signal control system determines duration of a green light and the duration of a red light based a roadway traffic light duration calculation formula according to the number of the waiting people. A traffic system of the invention is low in reformation cost, the duration of traffic lights can be dynamically set according to the number of the waiting people at the pedestrian crossing, and the pass capacity and the service level of the pedestrian crossing are improved; when the number of people passing is less, pass priority is given to a vehicle, and the passing capacity of vehicles on a road section is improved; and when there are many people to pass, priority is given to pedestrians, the waiting time of the pedestrians is improved, and potential traffic safety hazards at intersections are reduced.

Description

technical field [0001] The invention belongs to the technical field of intelligent transportation, and in particular relates to a traffic light time control method applied to two-way multi-lane pedestrian crossings. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] The current traffic signal light control system at the intersection usually sets the duration of the traffic light as a fixed value. In the two-way multi-lane pedestrian crossing scene, if there are no pedestrians or fewer pedestrians in the red light state (the roadway red light state), the vehicles will be forced to wait; When many pedestrians are waiting, some pedestrians are forced to wait for more than one red light before they can pass; resulting in a decrease in traffic capacity and a waste of traffic resources. In addition, most intersections are currently equipped with video surveillance equipment to monitor and record the traffic ...

AI Technical Summary

Problems solved by technology

[0005] (1) The fixed duration of traffic lights at two-way multi-lane crossings leads to low traffic capacity and service level

[0006] (2) The control system or equipment for the traffic light time in the prior art cannot be realized based on the existing traffic light equipment, and new equipment needs to be installed, and the transformation cost is high

[0007] (3) The existing control system not only detects pedestrian data but also vehicle data, resulting in a large amount of detection data, slow operation speed, low efficiency, and high error rate; at the same time, some existing control systems control the time of traffic lights at any time, resulting in time changes , the system is unstable

[0009] The main problems of the transformation are the cost, efficiency and system stability of the transformation
