Pedestrian traffic light and motor vehicle control method

Abstract

The invention relates to a pedestrian traffic light and motor vehicle control method, including the following steps: (1) a control button is manually pressed; (2) a control system acquires traffic state data of the crossing from traffic light control systems of crossings at the two ends of the road, the data is analyzed, and a time period with minimal traffic flow of the road in a preset time range is judged; (3) in the time period with minimal traffic flow, the green light in pedestrian direction is turned on while the red light in motor vehicle direction is turned on; (4) at or before the moment that the green light in pedestrian direction is turned on, a vehicle barrier cross bar arranged on the ground is lifted up to stop the motor vehicles from entering the pedestrian crossing. By adopting the method, pedestrian can be allowed to pass while the motor vehicle flow on the road is small, thus reducing the influence on motor vehicles and the whole road traffic condition while ensuring the passing of the pedestrian.

Description

technical field [0001] The invention relates to a method for controlling pedestrian crossing traffic lights and motor vehicles, and belongs to the technical field of traffic 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 traffic, the crosswalk should be provided with traffic lights for pedestrians and vehicles. Control so that the two cannot cross 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 ...

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, motor vehicles will be released all the time, which is conducive to improving the traffic capacity. However, the green light time in 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

[0004] In addition, because only red lights are used to control motor vehicles not to enter crosswalks, in some places without cameras, some drivers may not stop at red lights and drive across crosswalks in order to save time, especially at night when there are few pedestrians. Under the circumstances, it will pose a threat to the safety of pedestrians
