Embodiment Construction

[0033] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0034] In the embodiment of the present invention, the application scenarios are as follows figure 1 It means that traffic flow monitoring equipment and violation monitoring equipment are installed on the roads in both directions of uplink and downlink. The monitoring range of the camera is 100 meters long, and it can monitor the pedestrian waiting area on both sides of the zebra crossing. The invention uses video image recognition technology, the server analyzes the real-time video images collected by the intersection monitoring equipment, recognizes and determines the number of pedestrians and ve...

Abstract

The invention discloses a traffic light time control method for a two-way multi-lane zebra crossing intersection. A video monitoring device arranged at a zebra crossing intersection identifies and collects the number of vehicles waiting at the intersection and the number of pedestrians waiting at the two sides of the zebra crossing and identifies and determines a traffic flow situation; accordingto the vehicle number and pedestrian number as well as the traffic flow situation, processing is carried out based on different conditions; and a traffic light control system calculates green light lasting time and red light lasting time respectively based on the waiting vehicle number and waiting pedestrian number according to a lane traffic light lasting time calculation formula. Therefore, a problem of traffic resource wasting caused by fixed setting of the traffic light lasting time of the two-way multi-lane zebra crossing intersection is solved.

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 at a two-way multi-lane zebra crossing. Background technique [0002] 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 zebra crossing scene, if there are no pedestrians or fewer pedestrians passing and more vehicles waiting in the red light state (carriageway red light state), or there are many pedestrians waiting in the green light state when there are no vehicles passing , will lead to a decrease in traffic efficiency and a waste of traffic resources. In addition, most intersections are currently equipped with video surveillance equipment to monitor and record the traffic conditions at the intersection. Therefore, the video surveillance equipment can be combined with the traffic signal light control sys...
