Intelligent traffic light control system and control method

Abstract

The invention discloses an intelligent traffic light control system and control method. The intelligent traffic light control system comprises a first traffic light which is arranged at a pedestrian crossing on the road, and a second traffic light, a plurality of waiting zones are symmetrically arranged at the two ends of the pedestrian crossing, multiple waiting lots are arranged at every waitingzone, and one power generator is laid in each waiting lot; the control system further comprises a controller, a piezoelectric sensor, a tachometer and a storage battery, the tachometer is installed on the first traffic light, and the tachometer, the piezoelectric sensor, the first traffic light and the second traffic light are all connected with the controller; the power generators device are connected with the storage battery which is used for supplying power to the control system. According to the intelligent traffic light control system and control method, the influence of the environmenton a recognition result of an intelligent traffic light recognition system can be reduced, the light change duration is further delicately controlled, the passage efficiency of pedestrians and vehicles is increased, hence, energy is conserved and emission is reduced.

Description

technical field [0001] The invention belongs to the technical field of intelligent traffic, in particular to an intelligent traffic signal light control system and control method. Background technique [0002] With the continuous increase of urban population and car ownership, as well as the continuous acceleration of the pace of urban life, the situation of "people and vehicles competing for the road" is happening all the time. On the one hand, "people and vehicles competing for the road" will easily make the already very congested urban traffic more congested; on the other hand, it will easily lead to the occurrence of traffic accidents. In order to solve the "people and vehicles competing for the road", traffic lights have been added to many road sections, which has alleviated the contradiction of "people and vehicles competing for the road" to a certain extent. However, most of the old traffic lights are controlled by classic timing. Because the control of the changing ...

AI Technical Summary

Problems solved by technology

[0004] 1) Unable to analyze the urgency of pedestrians when crossing the road

The existing intelligent traffic signal light control system and its control method only control the length of traffic light time control according to the number of pedestrians in the pedestrian waiting area, ignoring the urgent needs of special groups of people to cross the road;

[0005] 2) Lack of entertainment factor

The existing intelligent traffic signal light control system and its control method are only mechanically improving the passing efficiency of pedestrians and vehicles, and have never considered entertainment factors such as fun;

[0006] 3) There are flaws in the energy-saving design

However, the power generation of solar panels is greatly affected by the weather, and it is often impossible to generate electricity normally in dark nights, rainy days, and severe smog in winter

There are flaws in the energy-saving design of intelligent systems;

[0007] 4) Recognition technology is greatly affected by environmental factors

In sunny mornings and nights with backlighting and poor lighting, the image processing system cannot accurately analyze the number of pedestrians or even whether there are pedestrians in the pedestrian waiting area due to the poor image acquisition effect.

[0008] 5) The degree of refinement of control needs to be further improved

Most of the existing intelligent traffic lights and their control systems adjust the duration of red and green lights in the direction of pedestrians based on whether there are pedestrians in the pedestrian waiting area or the number of pedestrians in the pedestrian waiting area. Distinguished consideration from minors, and the design of pedestrian waiting areas has not been incorporated into the intelligent traffic signal light system, and the degree of refinement of signal light time control needs to be further improved
