The present invention provides a control method of an intelligent traffic control system based on YOLO visual perception, and belongs to the technical field of traffic control. An intelligent traffic control system based on YOLO visual perception includes a video acquisition and processing module and a control module; the present invention connects a camera at an intersection through the video acquisition and processing module, captures the captured video image, analyzes and extracts the image feature information and converts it into control information, and at the same time, the video acquisition and processing module is connected to the control module for communication, and the control module is connected to the traffic light at the intersection, so that the control module can receive the control information and adjust the duration of the traffic light at the intersection in real time according to the control information, that is, according to the traffic volume of different lane types in different directions of the intersection, the duration of the traffic light at the corresponding intersection is controlled in real time, and the duration of the traffic light at the intersection is intelligently and dynamically adjusted, which effectively avoids the problem of traffic congestion in one direction and empty traffic in the other direction in actual road conditions, and improves the traffic efficiency of the road.

The application discloses a method, device and equipment for generating a U-turn trajectory based on automatic driving and a medium. The method comprises the following steps: when a vehicle drives to a preset U-turn section, a U-turn space is discretely sampled to obtain a sampling point, wherein the U-turn space is a space between a current lane of the vehicle and an opposite lane in which the vehicle can make a U-turn, and the sampling point is a position on a center line of the U-turn space that is passed by the vehicle when making a U-turn; a vehicle adjustment space is constructed according to a total width of the current lane of the vehicle and the opposite lane and a length of the U-turn space; and a vehicle U-turn trajectory is generated by a preset path planning method according to a current position of the vehicle, the sampling point, the vehicle adjustment space and a road condition of a lane to be driven into. The method can solve the problem that a U-turn trajectory cannot be flexibly generated in the prior art.
