Control system for traffic signal lamp

Abstract

The invention discloses a control system for a traffic signal lamp. The system includes an image acquisition module, an image processing module, a time distribution module, and a signal lamp control module. The image acquisition module separately obtains road surface images of road sections intersecting at a same intersection; the image processing module detects vehicle characteristics from the images, and separately counts traffic flow data of vehicles travelling in different directions on each of the road sections; the time distribution module comprehensively analyzes the traffic flow data of the vehicles traveling in different directions each of the road sections, and calculates the light-up time of a pass signal lamp and a forbidding signal lamp corresponding to each of the road sections, so that the vehicles on each of the road sections pass through the intersection in the shortest time; and the signal lamp control module separately controls light-on and light-off of the traffic signal lamps corresponding to each of the road sections, according to a calculated calculation result of the light-up time of the traffic signal lamps corresponding to each of the road sections. The control system for the traffic signal lamp achieves optimized distribution of the lighting time of the traffic signal lamps disposed on traffic intersections corresponding to each of the road sections,thus helping to reduce a situation of vehicle backlog on traffic road sections.

Description

technical field [0001] The invention relates to the technical field of intelligent traffic, in particular to a traffic signal lamp control system. Background technique [0002] Transportation plays a vital role in the development of urban economy and society, and is closely related to people's daily life. However, with the rapid economic and social development and the acceleration of urbanization, the number of motor vehicles has increased rapidly, and urban traffic problems have become increasingly serious. [0003] This phenomenon exists in road traffic. At some intersections crossed by multiple roads, the traffic volume of vehicles traveling along a certain road at the same intersection is relatively large, while the traffic volume of vehicles traveling along other roads is small, but the traffic volume corresponding to each road is relatively small. The lighting time of the traffic signal lights set on the road is the same, so it is easy to cause a backlog of vehicles i...

[0003] This phenomenon exists in road traffic. At some intersections crossed by multiple roads, the traffic volume of vehicles traveling along a certain road at the same intersection is relatively large, while the traffic volume of vehicles traveling along other roads is small, but the traffic volume corresponding to each road is relatively small. The lighting time of the traffic lights set on the road is the same, so it is easy to cause a backlog of vehicles in the lane with a large traffic volume, which reduces the efficiency of urban road operation

Moreover, since the vehicle is still in working condition while waiting for passage, it will produce a large amount of toxic gas and suspended particles, which will affect the natural environment.
