Embodiment Construction

[0017] The traffic flow direction distribution diagram of the intersection traffic signal light real-time control system is as follows figure 1 As shown, the traffic flow distribution diagram at the intersection only shows one of various types of traffic flow distribution and its traffic flow control, and the real-time control system of traffic signal lights at intersections for other types of vehicle flow distribution and traffic flow control can be easily obtained by analogy. figure 1 In the middle, when the red light is on in the east-west direction, in the north-south direction, A is the time when the green light is on for the straight-through and right turn, and B is the time for the green light for the left turn to be on

[0018] The schematic diagram of embedding the laser diode is as follows figure 2 shown. Its structure includes: steel pipe (1), cover plate (2), round glass sheet (3), laser diode kit (4), fixing plate (5), screw kit (6), bracket (7), junction box ( ...

Abstract

The invention relates to a real-time control system for traffic signal lamps at a crossroad. A road section near a lane exit is set as a red light waiting road section, each of lane exits at the crossroad and waiting entrances at the waiting road section is provided with a pair of infrared radiation devices, the infrared radiation devices at the waiting entrances are matched with the infrared radiation devices at the lane exits for counting the vehicle number in the waiting sections of lanes, and the vehicle number is the basis of the green light time for the lane vehicles.

Description

(1) Technical field: [0001] The invention relates to a real-time control system for traffic signal lights at crossroads. The road section near the outflow exit of the lane is set as a red light waiting section, and a pair of infrared contrasting devices are installed at the outflow of each lane at the intersection and at the waiting entrance of the waiting section. , the infrared contrast device at the waiting entrance cooperates with the infrared contrast device at the exit of the lane to count the number of vehicles entering the waiting section of the lane, which is the basis for the vehicle release time of the lane. (two) background technology: [0002] With the rapid development of my country's economy, the number of urban motor vehicles and the total traffic volume continue to increase, and the corresponding road infrastructure construction is difficult to keep up with in time. capacity bottleneck. Therefore, it is an urgent problem to improve the control ability of tra...
