Control system and method for dynamically adjusting traffic light time

Abstract

The invention discloses a control system and method for dynamically adjusting traffic light time. The system comprises a traffic light display module, a sensing device, a vehicle event recognition device and a master controller. The traffic light display module is used for displaying red, green and yellow signal lights and numbers, and the sensing device is used for sensing the traffic flow on a road; the vehicle event recognition device is used for recognizing vehicle events on a road; the traffic light display module, the sensing device and the vehicle event recognition device are respectively connected with the main controller. By arranging the sensing device and the vehicle event recognition device, the traffic flow and the vehicle events on the road can be effectively obtained, so that the traffic light time can be dynamically adjusted according to the traffic flow and the vehicle events on the road, the road resources are saved, and the energy consumption and waste pollution are reduced; in addition, the sensing device and the vehicle event recognition device are arranged, so that the accuracy of recognizing the road vehicle congestion condition can be improved, and the traffic light time can be accurately adjusted.

Description

technical field [0001] The invention relates to the technical field of time control of traffic lights, in particular to a control system and method for dynamically adjusting the time of traffic lights. Background technique [0002] For orderly and smooth traffic on the road, traffic lights at crossroads are essential. The current traffic lights are basically fixed according to the current traffic flow in different time periods such as morning peak, evening peak, flat peak, and low valley. The traffic lights in each direction take a long time. In this way, there are often red lights in the direction with cars, and green lights in the direction without cars for a long time. The actual road vehicle conditions and traffic control signals are not synchronized, which wastes existing road resources. In addition, the traffic lights are fixed. Although most of the time the intersection is smooth, the duration of the traffic lights does not match the actual traffic flow when sudden ch...
