Problems solved by technology

[0006] For this reason, the technical problem to be solved by the present invention lies in the problem that in the prior art, when a traffic jam is about to occur at an intersection controlled by signal lights, the motor vehicle cannot be prompted in time not to enter the intersection and at the same time record the illegal behaviors of following a green light and running a red light, thus proposing a System and method capable of prompting and preventing motor vehicles from following green lights to block intersections and running red lights

Embodiment 1

[0039] In this embodiment, a system that can prompt and prevent motor vehicles from following up with green lights to block intersections and run red lights, 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 shown.

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

[0042] Prompt unit: when the intersection is about to be congested, it reminds motor vehicles not to enter the intersection;

[0043] Control unit: judge whether the current signal light is a green light, if it is, calculate the transit time T required by the motor vehicle to pass through the intersection, and monitor the remaining time t of the green light in the current direction in real time, if the required transit time T is greater than the remaining time t of the green light, Then it shows that the crossing is about to ...

Embodiment 2

[0053] This embodiment provides a system and method that can prompt and prevent motor vehicles from following up with green lights to block intersections and run red lights, such as image 3 shown, including the following steps:

[0054] S1: Real-time continuous tracking of each motor vehicle entering the intersection.

[0055] S2: Detect the speed of each motor vehicle crossing the stop line.

[0056] S3: Determine whether the signal light in the current direction is a green light, if so, calculate the transit time T required for the motor vehicle to pass through the intersection, and monitor the remaining time t of the green light in the current direction in real time, if the required transit time T is greater than the remaining time t of the green light, Then it shows that the crossing is about to be congested, and the motor vehicle is prompted not to enter the crossing through the prompt unit.

[0057] The concrete implementation mode of this step is: calculate T=L / V, wh...

Abstract

The invention provides a system and method for preventing a motor vehicle from rushing for a green light to block a road junction and running a red light in a reminding mode. The method includes the steps that the speed of the motor vehicle getting over a parking line is detected; the passing duration needed for the motor vehicle to pass through the road junction is calculated with the speed of the motor vehicle, and the residual time of the current green light in the green light direction is monitored in real time, if the needed passing duration is larger than the residual time of the green light, the motor vehicle is reminded not to enter the road junction through a prompting unit. By means of the mode, when congestion is about to happen at the road junction, the motor vehicle can be reminded not to enter the road junction so that the phenomenon that the motor vehicle rushes for the green light when a driver see the green light when road junction is about to be congested can be effectively prevented, and smoothness in the non-congested direction of the road junction is ensured. On the basis, monitoring of the illegal act of running the red light is provided, the motor vehicle entering the road junction at the non-green-light time is photographed, and the act of running the red light is effectively supervised.

Description

technical field [0001] The invention relates to the field of traffic law enforcement, in particular to a system and method capable of prompting and preventing motor vehicles from blocking intersections with green lights and running red lights. 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 through the intersection. At this time, the driver should stop the motor vehicle outside the intersection, otherwise, he will not be able to leave...
