Intelligent traffic lights

Abstract

The adaptive intelligent signal light controller of the intelligent traffic light control system generates 3D images based on the real-time traffic data collected by the rotating laser radar and solid-state laser radar erected above the intersection, and cooperates with the millimeter wave radar erected next to each traffic light , stereo cameras and other sensors to generate accurate real-time 3D image data at intersections, which can generate 120 3D images per second, and the operating system of the adaptive intelligent signal light controller will automatically analyze the traffic where it is based on the collected 3D image data The real-time environmental information of vehicles, pedestrians, and road surfaces at the intersection is calculated and analyzed. The adaptive intelligent signal light controller flexibly changes the traffic lights according to the real-time traffic conditions of vehicles and pedestrians at each intersection, which can efficiently guide vehicles and pedestrians at the intersection. Vehicles and pedestrians in the east-west direction will have passed through completely, and the north-south direction cannot be changed to green light in time, and the vehicles and pedestrians in the north-south direction can only wait for the red light to count down. It also improves the unnecessary congestion problem caused by the decrease of the actual traffic capacity of the intersection and the long delay time of vehicles passing the intersection due to the unsatisfactory control strategy of the current urban traffic lights.

Description

Technical field [0001] The invention relates to an intelligent traffic light control system based on a rotary laser radar, a solid laser radar, a millimeter wave radar and a stereo camera, which is used for intelligent and self-adaptive control of traffic lights at intersections. Background technique [0002] With the development of society and economy, the number of urban vehicles has grown rapidly, traffic congestion has become increasingly serious, and the negative effects such as traffic accidents and environmental pollution have become increasingly prominent. Urban traffic problems directly restrict urban construction and economic growth, and are closely related to people's daily lives. Especially during the rush hour, the huge traffic volume makes the road congested, causing unnecessary time waste and economic loss. Therefore, it is necessary to design a reliable, safe and convenient intelligent traffic light adaptive control system. [0003] Usually traffic congestion is m...

Problems solved by technology

[0003] Usually, traffic jams are mostly due to the fact that the traffic lights cannot change the lights according to the real-time road conditions at the intersection, causing vehicles and pedestrians in the east-west direction to pass through completely, failing to change the lights in the north-south direction to green lights in time, and vehicles and pedestrians in the north-south direction. You can only wait for the red light to count down. This traditional traffic light is very unintelligent, which is not conducive to the efficient diversion of traffic at the intersection.
