Efficient and safe pedestrian crossing traffic light control system

Abstract

The invention relates to an efficient and safe pedestrian crossing traffic light control system, comprising a central processing unit, a pedestrian data acquisition unit, a traffic light control unit, a vehicle barrier cross bar control unit and a vehicle barrier cross bar mechanism; wherein the pedestrian data acquisition unit acquires pedestrian quantity at the two ends of the pedestrian crossing, the central processing unit calculates a time period with minimal traffic flow in a permissive time range, determines the green light starting time and time duration in the pedestrian direction and generates a traffic light control instruction and a vehicle barrier cross bar control instruction, the traffic light control unit is connected with the central processing unit by a signal wire, and the vehicle barrier cross bar control unit is connected with the central processing unit by the signal wire. The invention can allow the pedestrian to pass when the motor vehicle flow on the road is small, so as to ensure the passing of the pedestrian while reducing the influence on the motor vehicle and the whole road traffic condition to the utmost extent.

Description

Technical field [0001] The invention relates to an efficient and safe pedestrian crossing traffic light control system, which belongs to the technical field of electronic control. Background technique [0002] In the middle of a long road, it is usually necessary to set up a setting for pedestrians to cross the road, such as a flyover or a crossroad, but the lowest construction cost is the crosswalk. On the road with a little more traffic, the crosswalk should be set 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 crossings. One is periodic traffic light switching, and the other is with a delay button. After a certain period of time, the green light in the pedestrian direction will light up and pedestrians can cross the road. [0003] Using the pedestrian direction green light delay button control method 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

However, when there are too many pedestrians congested on both sides of the road, this delay control technology cannot adjust the starting time and length of time for releasing pedestrians at any time, causing inconvenience to pedestrians.
