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.
