Embodiment Construction

[0067] Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The same reference numerals denote the same or similar structures in the drawings, and thus their repeated descriptions will be omitted.

[0068] Such as figure 1 As shown, the present invention provides a traffic light phase control method, comprising the following steps:

[0069] S100: Collect current intersection status data, the intersection status data including vehicle status data of each lane at the intersection;

[0070] S200: Input the intersection state data at the current moment into the trained traffic light phase model;

[0071] S300: Control the ...

Abstract

The invention provides a traffic light phase control method, system and device and a medium, and the method comprises the steps: collecting intersection state data at a current moment, wherein the intersection state data comprises the vehicle state data of all lanes of an intersection; inputting the intersection state data at the current moment into a trained traffic light phase model; and controlling the phase of the traffic light according to the traffic light phase state output by the traffic light phase model. According to the invention, the intersection state data and the traffic signal lamp phase data are collected, and the phase change mode of the traffic signal lamp can be better selected by adopting the machine learning model, thereby realizing adaptive adjustment of the traffic signal lamp, and effectively reducing the traffic jam condition.

Description

technical field [0001] The present invention relates to the technical field of signal light control, in particular to a traffic light phase control method, system, equipment and medium. Background technique [0002] With the continuous development of economy and urban infrastructure, the problem of road traffic congestion has become more and more obvious. It is very important to reasonably plan the phase transformation of traffic lights in the road network, which can effectively reduce road congestion. At present, the commonly used traffic light phase model training methods can be mainly divided into two types: manual control and computer program control. [0003] Since manual subjective judgment is relatively accurate, combined with the real-time video stream of surveillance cameras, manual control of the phase transformation of traffic lights can effectively solve the problem of intersection congestion. However, for the phase model training of city-level traffic lights, ...
