specific Embodiment approach 1

[0031] Specific implementation mode one: see figure 1 Describe this embodiment, a method for identifying whether a right-turning motor vehicle is courteous to pedestrians described in this embodiment, the method is realized based on a traffic monitoring system, and the deceleration identification is delineated behind the stop line (2) of each right-turning lane line(1);

[0032] When the motor vehicle is turning right, it enters the area between the stop line (2) and the deceleration identification line (1) and two conflict areas in sequence, and the two conflict areas are respectively defined as the first conflict area and the second conflict area; The first conflict area is the rectangular area formed by the intersection of the extension of the right-turn lane and the crosswalk before the vehicle turns right, and the second conflict area is the rectangle formed by the intersection of the extension of the right-turn lane and the crosswalk after the vehicle turns right area; ...

specific Embodiment approach 2

[0038] Specific implementation mode two: see figure 1 Describe this embodiment. The difference between this embodiment and the method for identifying whether a right-turning motor vehicle yields to pedestrians described in Embodiment 1 is that the area between the stop line (2) and the deceleration identification line (1) is The specific process of vehicle speed detection to determine whether the motor vehicle yields to pedestrians is as follows:

[0039] The vehicle speed in the area between the stop line (2) and the deceleration identification line (1) is monitored through the video display platform in the traffic monitoring system. Capture and record the impolite behavior of right-turning motor vehicles, so as to determine whether the motor vehicles are courteous to pedestrians.

[0040] In this embodiment, the deceleration identification line (1) is set in such a way that the vehicle speed can be reasonably decelerated before entering the two conflict areas. Once pedestri...

specific Embodiment approach 3

[0041] Specific implementation mode three: see figure 1 Describe this embodiment. The difference between this embodiment and the method for identifying whether a right-turning motor vehicle is courteous to pedestrians described in Embodiment 1 is that the vehicle speed detection is performed on the first conflict area to determine whether the motor vehicle is courteous to pedestrians. The specific process is:

[0042] Step 11: The main controller in the traffic monitoring system judges whether the pedestrians in the first conflict zone arrive before the motor vehicle, if the judgment result is yes, execute steps 1 and 2, if the judgment result is no, execute steps 1 and 3;

[0043]Step one and two: judge whether the vehicle speed is 0, if the judgment result is yes, it is determined that the motor vehicle is courteous to the pedestrian, if the judgment result is no, it is determined that the motor vehicle does not give courtesy to the pedestrian, and video recording is perform...

Abstract

A method for identifying whether right-turning motor vehicles yield to pedestrians or not belongs to the field of traffic engineering and solves a problem that whether right-turning motor vehicles yield to pedestrians or not cannot be judged accurately in the prior art. The method is implemented based on a traffic monitoring system. A speed cut identification line is set behind a parking line of each right-turn lane. When motor vehicles turn right, the motor vehicles enter an area between the parking line and the speed cut identification line and two conflict areas in sequence. The method includes steps that traffic conditions of a right-turn lane and crosswalks are recorded in real time through a traffic monitoring system; when pedestrians in the crosswalk of the first conflict area has way right, the traffic monitoring system performs vehicle speed detection on the area between the parking line and the speed cut identification line and the first conflict area; when pedestrians on thecrosswalk of the second conflict area has way right, the traffic monitoring system performs vehicle speed detection on the second conflict area, so that whether the motor vehicles yield to the pedestrians or not can be determined. The method is mainly used for effective judgment on yield-to-the pedestrian behaviors.

Description

technical field [0001] The invention belongs to the field of traffic engineering. 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. The third paragraph of Article 38 of the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China" stipulates: "When the red light is on, vehicles turning right can pass without hindering the passage of the released vehicles and pedestrians." In addition, Article 47 of the "Road Traffic Safety Law of the People's Republic of China" stipulates: "When a motor vehicle passes a crosswalk, it shall slow down; when a pedestrian is passing a crosswalk, it shall stop and give way." However, due to the lack of effective technical identification methods and regulatory measures, the current implementation of this regulation is very dif...
