Embodiment 1

[0036] In this embodiment, a system for preventing motor vehicle green lights from following up to block intersections is provided, such as figure 1 As shown, it is set at the intersection, and the schematic diagram of the setting is as follows figure 2 shown, including:

[0037] Video tracking unit: real-time and continuous tracking of each motor vehicle entering the intersection;

[0038] a speed detection unit, which detects the speed of the motor vehicle crossing the stop line;

[0039] Control unit: Calculate the passing time required for the motor vehicle to maintain the speed through the intersection, and compare it with the remaining time of the green light in the direction of release, if the required passing time is greater than the remaining time of the green light, control the green light in this direction to turn into a light , the process of changing the light is to first turn the green light into a yellow light, and then turn the yellow light into a red light....

Embodiment 2

[0047] In this embodiment, a method for preventing motor vehicle green lights from following up to block intersections is provided, such as image 3 shown, including the following steps:

[0048] S1: Real-time continuous tracking of each motor vehicle entering the intersection.

[0049] S2: Detect the speed of the motor vehicle crossing the stop line.

[0050] S3: Calculate the passing time required to pass through the intersection at the speed of the motor vehicle, and compare it with the remaining time of the green light in the direction of release. If the required passing time is greater than the remaining time of the green light, control the green light in this direction to change. Describe the process of changing the light, including first changing the green light into a yellow light, and then changing the yellow light into a red light.

[0051] The concrete implementation mode of this step is: calculate T=L / V, wherein, T=the time that current speed passes through the i...

Abstract

The invention provides a system for preventing motor vehicle green-light following intersection blocking. The speed of a motor vehicle over a stop line is detected, the passing time required when the motor vehicle passes through an intersection at the speed is calculated and compared with the remaining time of the green light in the releasing direction, and if the required passing time is longer than the remaining time of the green light, the green light in the direction is controlled to be switched into the red light. By means of the mode, the vehicle can be prevented from entering the intersection in a light switching mode when the intersection is blocked, as red light running belongs to illegal acts, green-light following generated when blocking occurs can be effectively avoided, and the passing efficiency of the intersection is guaranteed. According to the scheme, the signal light is controlled to be switched into the red light instead of a reminding board, as law enforcement can not be carried out when driving does not conform to the reminding board, the reminding board only has the reminding effect, law enforcement can be facilitated in the light switching mode, and the good passing order can be easily established.

Description

technical field [0001] The invention relates to the field of traffic law enforcement, in particular to a system and method for preventing motor vehicles from following green lights to block intersections. Background technique [0002] In order to ensure orderly, safe and smooth traffic at intersections, the traffic management department has set up intersection control signal lights at intersections where the hourly traffic flow of motor vehicles reaches the prescribed standard. Under normal circumstances, signal lights control intersections can replace the role of police command. When there is an accident at the intersection or rain and snow cause congestion ahead, the speed of motor vehicles entering the intersection during green light time will be much lower than the normal speed of passing the intersection. At this time, the driver should stop the motor vehicle outside the intersection, otherwise, he will not be able to leave the intersection when the red light is on, cau...
