Embodiment 1

[0039] In this embodiment, a system is provided to prevent motor vehicles from running through red lights and green lights to follow up and cause blocking intersections, such as figure 1 shown, including:

[0040] Video tracking unit: real-time continuous tracking of each motor vehicle entering the intersection, set at the intersection, such as figure 2 as shown,

[0041] A speed detection unit, which detects the speed of each motor vehicle crossing the stop line;

[0042] Control unit: judge whether the signal light in this direction is a green light, if so, calculate the passing time T required for the motor vehicle to pass through the intersection at this speed, and constantly compare T with the remaining time t of the green light in the direction of release, if required When the passing time T is greater than the remaining time of the green light t, the green light in this direction is controlled to change to a light; if the direction has changed to a red light, the motor...

Embodiment 2

[0051] In this embodiment, a method for preventing motor vehicles from running red lights and green lights to follow up and block intersections is provided, such as image 3 shown, including the following steps:

[0052] S1: Real-time continuous tracking of each motor vehicle entering the intersection;

[0053] S2: Detect the speed of the motor vehicle crossing the stop line;

[0054] S3: If the signal light in this direction is green, calculate the passing time T required for each motor vehicle to pass through the intersection, and constantly compare it with the remaining time t of the green light in this direction, if the required passing time T is greater than the green light For the remaining time t, control the green light in this direction to change to light;

[0055] The concrete realization mode of this step is: calculate T=L / V, wherein, T=every motor vehicle passes the time that crossing needs, the length of the stop line of L=release direction to the other side's s...

Embodiment 3

[0062] In this embodiment, a method is provided to prevent motor vehicles from running red lights and following green lights to cause blocking intersections, such as Figure 4 Shown:

[0063] S1: Continuously track each motor vehicle;

[0064] S2: Determine whether the signal light in this direction is green, if yes, go to S3, otherwise, go to S5:

[0065] S3: Real-time detection of the speed V of each motor vehicle arriving at the stop line, and real-time calculation of the time T=L / V required for the motor vehicle arriving at the stop line to pass through the intersection at the current speed, where L is the width of the intersection;

[0066] S4: Real-time detection of the remaining time t of the current green light, as shown in the figure T>t, then the signal light of the control direction turns yellow and then red, and the number plate recognition is performed while taking pictures of each vehicle that crosses the stop line, and the The recognized license plate number i...

Abstract

The invention provides a system for preventing intersection congestion caused by red light violation and green light follow-up of motor vehicles. The speed of each motor vehicle is detected in real time when the motor vehicles get over a stop line; the needed passing time for each motor vehicle to pass through an intersection is worked out, the needed time T for the nearest motor vehicle to get over the stop line is compared with green light remaining time t of the release direction, and if the needed passing time T is longer than the green light remaining time t, the green light is controlled to become the red light in the release direction. In the mode, when the intersection is congested, the vehicles are prevented from continuing to get into the intersection in a light changing mode; when the red light is switched on, if the motor vehicles continue to get over the stop line and get into the intersection, red light violation behaviors of the motor vehicles can be recorded by the system, intersection congestion aggravation is prevented, and equipment investment is also saved. The red light violation behaviors are also recorded, traffic law enforcing power is enhanced, illegal behaviors are cracked down, a good passing order is built easily, and traffic safety performance is improved.

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 running red lights and 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 t...
