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

Embodiment Construction

[0011] A traffic light control method for a crosswalk, comprising the following steps:

[0012] (1) Press the control button manually;

[0013] (2) The control system obtains the traffic status data of the intersection from the traffic light control system at the intersection of both ends of the road, and analyzes the data to determine the time period of the minimum motor vehicle flow in the road section within the set time range;

[0014] (3) Control the green light in the direction of pedestrians and the red light in the direction of vehicles to be on during the time period when the traffic flow is the smallest within the set time range.

[0015] In step (1), control buttons are set at the crossroads at both ends of the crosswalk according to the usual way, and the signal is sent to the control system, and the control system only responds to the first button signal within one release period.

[0016] In step (2), the traffic status data at the intersections at both ends inc...

Abstract

The invention relates to a crosswalk traffic-light control method, which comprises the following steps that: (1) a control button is manually pressed; (2) a control system acquires traffic-state data of intersections from a traffic-light control system for the road intersections at two ends, analyzes the data, and determines a time segment with minimum vehicle flow of a road section within a set time range; and (3) in the time segment with the minimum vehicle flow within the set time range, a pedestrian-direction green light is controlled to be on, while a vehicle-direction red light is controlled to be on. The method 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 method for a crosswalk, belonging 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 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 flow of the road. W...
