Problems solved by technology

However, there are some problems with this buffer in the form of time: First, according to the current traffic regulations, "running a yellow light" should be an illegal act, but because "running a yellow light" is sometimes difficult to define, in many cases the driver is not subjective "Running the yellow light", so some local law enforcement departments judged "if the yellow light is on, the motor vehicles that have not crossed the stop line will continue to pass" as a traffic violation, which has caused widespread controversy
It is difficult to fully implement the illegal determination and punishment of running a yellow light, which also leads to the frequent phenomenon of running a yellow light, which poses a great safety hazard
Second, because the yellow light buffer is time-dependent, the driver may not be able to accurately judge the duration of the yellow light. As a result, the phenomenon of "deliberately running a yellow light" to "running a red light" also occurs from time to time, which is easy cause traffic accident
Third, many intersections do not have a countdown timer for the green light, and they will not flash when the green light turns to amber. Drivers cannot be sure when the yellow light will turn on. Sudden braking when the yellow light is on can easily cause rear-end collisions.
[0003] There are some problems in the use of yellow lights, especially the judgment of "running a yellow light" has not been solved well
But if there is no yellow light, then there will be the same problem in the judgment of "running the yellow light", and there will be a greater safety hazard

Embodiment 1

[0064] Embodiment 1: For example, refer to figure 2 As shown, red and green traffic lights and red stop lines should be set up at intersections. Assuming that the speed limit of the road is 60km / h, a smooth flow detection line and corresponding capture system trigger device shall be set 45m behind the stop line set at the intersection, and a congestion detection line and corresponding capture system trigger shall be set 15m behind the stop line set at the intersection device. Assuming that it is currently in the unblocked time period, the indicator light of the unblocked detection line is on at this time, the indicator light of the congestion detection line is off, and the unblocked detection line is an effective detection line. The red light is not yet on, and vehicle A passes the unblocked detection line at a speed of 50km / h. At this time, the capture system will not be triggered to take pictures; when passing the congestion detection line, since the congestion detection l...

Embodiment 2

[0065] Embodiment 2: For example, refer to figure 2As shown, red and green traffic lights and red stop lines should be set up at intersections. Assuming that the speed limit of the road is 40km / h, set up a smooth flow detection line and a corresponding capture system trigger device at 24m behind the stop line set at the intersection, and set a congestion detection line and corresponding capture system trigger at 8m behind the stop line set at the intersection device. Assuming that it is currently in a congestion period, the indicator light of the unblocked detection line is off, the indicator light of the congestion detection line is on, and the congestion detection line is a valid detection line. The red light is not yet on, and vehicle A passes the unblocked detection line at a speed of 20km / h. Since the unblocked detection line is not an effective detection line, it will not trigger the capture system to take pictures; when passing the congestion detection line, because t...

Embodiment 3

[0066] Embodiment 3: such as referring to figure 2 As shown, red and green traffic lights and red stop lines should be set up at intersections. Assuming that the speed limit of the road is 60km / h, a smooth flow detection line and corresponding capture system trigger device shall be set 45m behind the stop line set at the intersection, and a congestion detection line and corresponding capture system trigger shall be set 15m behind the stop line set at the intersection device. Assume that the current period is unblocked and the red light is not on. Vehicle C passes through the unblocked detection line and the congestion detection line at a speed of 70km / h. At this time, the capture system will not be triggered to take pictures, and then the red light is on, and the red light capture system is activated. Afterwards, vehicle C passes the stop line at the same speed, triggering the capture system to take pictures. Since only one image of car C passing the stop line was captured,...

Abstract

The invention discloses a detection method for improving road traffic safety. The method comprises steps of setting red and green signal lamps and a red light stop line at an intersection, and settinga detection line at a preset distance from the stop line in a vehicle driving direction; acquiring a red light signal and judging a red light state; acquiring image information of a vehicle passing through the detection line and the stop line when the red light is turned on; and judging whether the vehicle sequentially passes through a detection line and a stop line when the red light is turned on, and if so, determining that the vehicle runs the red light. The method is advantaged in that the detection line is set by calculating the sum of the reaction distance and the braking distance of the vehicle, whether the vehicle is safely parked in time or not is judged with the detection line as a reference, and powerful evidence is provided for punishment of red light running; the situation that when the yellow light is used, whether subjective intentional yellow light rushing is difficult to define or not is avoided, buffering in the distance form replaces buffering in the time form of the yellow light, and road traffic safety is effectively improved.

Description

technical field [0001] The invention relates to the traffic field, in particular to a detection method for improving road traffic safety. Background technique [0002] Nowadays, red, yellow and green traffic lights are mostly used at intersections. Among them, the yellow light is a kind of transition light for traffic information, which can provide a certain time buffer between the red and green lights, which is very important for drivers. To remind and warn the role. However, there are some problems with this buffer in the form of time: First, according to the current traffic regulations, "running a yellow light" should be an illegal act, but because "running a yellow light" is sometimes difficult to define, in many cases the driver is not subjective "Running a yellow light", so some local law enforcement departments judged "if the yellow light is on, motor vehicles that have not crossed the stop line continue to pass" as a traffic violation, which has caused widespread co...
