Crosswalk traffic-light control device

Abstract

The invention relates to a crosswalk traffic-light control device, which comprises a microprocessor and a traffic-light control module, wherein the microprocessor is provided with a communication module; the communication module communicates with a traffic control system of intersections at two ends of a road through a wired or wireless mode so as to acquire traffic-state data of the intersections at two ends, which is related to the road; according to preset road data and the related traffic-state data of the intersections at two ends, the microprocessor works out a time segment with minimum vehicle flow within a set time range, determines the time of a green light for allowing pedestrians to pass, and generates traffic-light control instructions; and the traffic-light control device is connected with the microprocessor through a signal line, and receives control signals output by the microprocessor to switch working states of traffic lights. The device can allow the pedestrians to pass under the circumstance that vehicles on the road is small in flow, thereby reducing the influence on the vehicles and overall road traffic conditions as much as possible while ensuring the passing of the pedestrians.

Description

technical field [0001] The invention relates to a traffic light control device for a pedestrian crossing, which belongs to the technical field of electronic control. Background technique [0002] In the middle of a long road, there are usually settings for pedestrians to cross the road, such as overpasses or tunnels, but the lowest construction cost is the crosswalk. In the section with a little more traffic, the crosswalk should be provided with traffic lights for pedestrians and vehicles. Control so that the two cannot pass at the same time to avoid traffic accidents. At present, there are two ways to control the traffic lights of the crosswalk, one is periodic traffic light switching, and the other is provided with a delay button. After a certain period of time, the green light in the pedestrian direction is on, and pedestrians can cross the road. [0003] The control method of using the green light delay button in the pedestrian direction can better ensure the smooth fl...

AI Technical Summary

Problems solved by technology

[0003] The control method of using the green light delay button in the pedestrian direction can better ensure the smooth flow of the road. When there are no pedestrians crossing the street, it is always in the direction of the motor vehicle, which is conducive to improving the traffic capacity. However, the green light time of the pedestrian direction controlled by this delay button Regardless of the flow of motor vehicles on the road, pedestrians may be released when the flow of motor vehicles is the largest, causing congestion of vehicles on the road
