specific Embodiment approach 1

[0014] Specific implementation mode one: a method for judging the traffic violation of a motor vehicle driver at a stop and give way intersection includes the following steps:

[0015] The object of the present invention is achieved in that the vehicle detector (the road is hereinafter referred to as "the main road") is respectively arranged on the entrance road with the right of way at the intersection to detect whether there is a vehicle arriving and the time and speed of arrival; Install a video detector above the stop and give way entrance to judge whether the arriving vehicle actively slows down and stops. If it does not slow down and stop, it will start electronic capture to obtain evidence of its illegal behavior; at the same time, install a traffic signal opposite the stop and give way entrance , when no vehicle arrives at the entrance road with the right of way or there is a vehicle arriving but there is a large enough traversable gap, the signal light will display a g...

specific Embodiment approach 2

[0022] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is: the distance between the starting position of the parking and yielding detection area and the parking line is L r The calculation formula is:

[0023]

[0024] where v max is the speed limit value of the stop and give way road, a is the vehicle deceleration, and the value is 3.0~3.5m / s 2 .

[0025] Other steps and parameters are the same as those in Embodiment 1.

specific Embodiment approach 3

[0026] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is: the specific process of determining the time required for the vehicle on the entrance road to stop and give way to cross the main road in the step two is:

[0027] Let L be the distance between the parking line at the entrance to give way and the edge of the conflict zone farthest from the parking line 0 , the length of the car is L v , the target speed is the road speed limit v max , then the time t required to accelerate to the target speed 1 And the traveling distance S is:

[0028]

[0029]

[0030] Where a is the vehicle acceleration, the value is 3.0~3.5m / s 2 ;

[0031] When L 0 +L v When 0 for:

[0032]

[0033] where t 0 is the reaction time of the driver;

[0034] When L 0 +L v When ≥S, it means that the vehicle accelerates to the target speed and then goes through a period of constant speed running before completely passing the conflict ...

Abstract

The invention provides a method for judging traffic violation of stopping to yield by motor vehicle driver at intersection. The method aims to solve the problem that the traffic accident risk of the intersection is high due to the fact that vehicles do not stop to give way to pedestrians at a parking way-giving intersection. The method comprises the following steps of 1) arranging a parking way-giving detection area on a parking way-giving inlet channel; 2) determining the time required by the vehicle to pass through the main road on the parking way-giving entrance lane; 3) arranging a vehicledetector on the road with the priority passing weight; 4) calculating the passing neutral gear of the two inlet channels with the priority passing right roads; 5) starting electronic snapshot evidence collection to catch an illegal behavior, when the vehicle enters the parking way-giving detection area, the speed is not reduced to zero and passes through the parking line, or during a red light, avehicle on the stop-giving entrance channel is forcibly driven away from the parking line. The invention is applied to the field of traffic engineering.

Description

technical field [0001] The invention relates to the field of traffic engineering, in particular to a method for judging traffic violations of a motor vehicle driver at a stop and give way intersection. Background technique [0002] With the continuous increase of the number of motor vehicles in our country, the number of vehicles on the road is increasing day by day, and the conflict between people and vehicles has intensified. Article 52 of the "Regulations for the Implementation of the Road Traffic Safety Law" stipulates: Motor vehicles passing through intersections that are not controlled by traffic lights or commanded by traffic police shall comply with Article 51 (2) and (3). In addition to the regulations, the following regulations should also be observed: (1) If there are traffic signs and line control, let the party with priority pass first; (2) If there is no traffic sign and line control, stop and look around before entering the intersection, let the right (3) Tur...
