Intelligent crosswalk traffic-light control device

Abstract

The invention relates to an intelligent crosswalk traffic-light control device, which comprises a microprocessor, a traffic-light control module and a pedestrian data acquisition unit, wherein the pedestrian data acquisition unit acquires the quantity of pedestrians at two ends of a crosswalk in real time; the microprocessor is provided with a communication module in order to obtain traffic-state data of intersections at two ends, which is related to a road; according to the related traffic-state data and pedestrian-quantity data of the intersections at two ends, with the support of preset programs, the microprocessor determines the starting time and time span of a green light allowing the 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 an intelligent pedestrian crossing traffic light control device, which belongs to the technical field of electronic control. Background technique [0002] In the middle of long roads, it is usually necessary to set up settings for pedestrians to cross the road, such as overpasses or underpasses. However, the construction cost is the lowest. Crosswalks. In sections with slightly more traffic, crosswalks should be set with traffic lights to prevent pedestrians and vehicles. Control so that both cannot pass at the same time to avoid traffic accidents. At present, there are two ways to control traffic lights at cross-street crossings. One is to switch the traffic lights periodically, and the other is to have a delay button. After a certain period of time, the green light in the direction of pedestrians will turn on, and pedestrians can cross the road. [0003] The control method of using the pedestrian direction green light delay ...

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

[0004] In addition, when there are too many pedestrians and congestion on both sides of the road, the delay control method cannot adjust the starting time and length of time for releasing pedestrians at any time, causing inconvenience to pedestrians
