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 car-man law enforcement camera in an untrusted-controlled street crossing passage. For the untrusted-controlled street crossing passage, the experimental group with the car-man law enforcement camera installed and the control group without the car-man law enforcement camera are respectively selected. , collect the data sets of the experimental group and the control group respectively, input the data sets into the binary logistic regression model and the ordinal logistic regression model, and obtain the regression vector coefficients output by the above models, when the first regression vector coefficient β m When greater than 0 / less than 0, it is determined that the installation of law enforcement cameras will increase / decrease the probability of vehicles giving way; when the second regression vector coefficient β m1 When it is greater than 0 / less than 0, it is determined that the installation of a law enforcement camera will increase / decrease the probability of vehicles legally giving way; when the third regression vector coefficient β m2 When it is greater than 0 / less than 0, it is determined that the installation of law enforcement cameras will increase / reduce the severity of pedestrian-vehicle conflicts; it can more accurately evaluate the impact of law enforcement cameras on pedestrian safety in related passageways.
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...
