Traffic control system based on pedestrian refuge island

Abstract

The invention discloses a traffic control system based on a pedestrian refuge island. comprising a camera device, an image processing device, traffic lights and a traffic light control device provided at the monitoring crossing, the camera device faces the pedestrian refuge island for monitoring the pedestrian situation on the pedestrian refuge island and shoots in a video manner, the image processing device performs real-time image processing on the video captured by the camera device and identifies the pedestrian distribution on the left and right sides of the pedestrian refuge island, the traffic light control device controls the traffic lights according to the pedestrian distribution on the pedestrian refuge island, when the pedestrians waiting at one side of the pedestrian refuge island exceed the set quantity, the traffic light control device performs linkage control of the vehicle traffic light and the pedestrian traffic light, so that the pedestrian traffic light corresponding to the passing direction of the side can emit the pedestrian passing signal for the waiting pedestrians to pass through. The invention discloses a traffic control method based on a pedestrian refuge island.

Description

technical field [0001] The invention belongs to the field of traffic control, and in particular relates to a traffic control system based on a pedestrian safety island, which realizes fair passage of people and vehicles and improves traffic efficiency. Background technique [0002] At present, the running time of traffic lights in each direction at each intersection of urban roads usually adopts a timing switching control mode, and the running time of traffic lights in each direction at each intersection is fixed. This control method using timing switching usually causes vehicles or pedestrians to "wait for nothing" to switch green lights. [0003] Although some intersections set different timing switching times for traffic lights according to the proportion of traffic volume, to a certain extent alleviate the phenomenon of vehicles or pedestrians "waiting" for green light switching, but the traffic volume at each intersection changes in real time. The switching control met...

Problems solved by technology

[0005] When the number of motor vehicle lanes is large, if there is no pedestrian safety island in the middle of the road, many pedestrians cannot walk across the road in the pedestrian green light signal, and can only stop in the middle of the traffic flow in the next pedestrian red light signal, or in the dense traffic. Forcibly passing through traffic can easily lead to traffic accidents
