Problems solved by technology
At crossing passages without signal control on the road section, due to the high speed of vehicles and the lack of signal lights to assign the right of way to pedestrians and motor vehicles, serious conflicts between pedestrians and vehicles are prone to occur, and pedestrian crossings pose a great safety hazard and the severity of accidents is high.
Therefore, there is an urgent need to study and solve the conflicts between pedestrians and vehicles and the problem of motor vehicle yielding in unlicensed crossing passages

The invention discloses a safety evaluation method for a vehicle-yielding law enforcement camera of a non-signal-control street-crossing channel, and the method comprises the steps of: respectively selecting an experiment group provided with a vehicle-yielding law enforcement camera and a control group not provided with a vehicle-yielding law enforcement camera for the non-signal-control street-crossing channel, and respectively collecting the collection data sets of the experiment group and the control group; inputting the data sets into a binary logistic regression model and a sequencing logistic regression model, acquiring each regression vector coefficient output by the models, and when a first regression vector coefficient beta m is greater than 0 / less than 0, determining that the vehicle yielding probability can be increased / reduced when the law enforcement camera is installed; when a second regression vector coefficient beta m1 is larger than 0 / smaller than 0, judging that the legal yielding probability of the vehicle can be increased / reduced when the law enforcement camera is installed; when a third regression vector coefficient betam2 is greater than 0 / less than 0, determining that the installation of the law enforcement camera can increase / reduce the severity of the man-vehicle conflict; according to the method, the influence of the related channel vehicle-yielding law enforcement camera on pedestrian safety can be accurately evaluated.
Description
technical field [0001] The invention relates to the technical field of road traffic, in particular to a safety evaluation method of a camera for law enforcement by a vehicle under untrusted control of a street crossing passage. Background technique [0002] Among the traffic accidents that have occurred in recent years, the number of accidents involving pedestrians and non-motor vehicles accounted for a large proportion. In 2018, a total of 244,937 traffic accidents occurred in a certain area, of which 28,601 were related to pedestrians and non-motor vehicles, accounting for 10% of the total. 11.68%, as a vulnerable group in the traffic system, pedestrians are the main victims of accidents, and the traffic safety issues related to pedestrians cannot be ignored. At crossing passages without signal control on the road section, due to the high speed of vehicles and the lack of signal lights to allocate the right of way for pedestrians and motor vehicles, serious conflicts betwe...
