Abstract

The present invention provides a method for analyzing the deterrent range of single-point speed measuring equipment on expressways. Based on the existing single-point equipment and accident big data, the accident density of the upstream and downstream of the single-point speed measuring equipment is calculated and calculated accurately through the accident density distribution curve trend graph. The effective deterrent range range of single-point speed measuring equipment for speeding violations; the basic data for calculation is based on historical data and does not rely on the personal experience of technicians to ensure accurate and objective deterrent range for speed measuring equipment.

Description

technical field

[0001] The invention relates to the technical field of intelligent traffic control, in particular to a method for analyzing the deterrent range of expressway single-point speed measuring equipment. Background technique

[0002] The expressway has the characteristics of being completely closed and the overall speed is high, and vicious traffic accidents occur frequently, and speeding is an important cause of accidents. According to the statistics. Traffic control departments usually rely on motor vehicle speedometers to investigate and deal with violations of speeding. At the same time, because drivers know the existence of speedometers, they will consciously control their speed, thereby reducing the probability of accidents before traffic accidents occur. Therefore, installing speed measuring equipment on expressways with a suitable density is also an effective means to reduce accidents; however, too dense installation of speed measuring equipment will lead ...

Embodiment Construction

[0031] A method for analyzing the deterrent range of expressway single-point speed measuring equipment in the present invention is characterized in that it includes the following steps.

[0032] S1: Based on historical data, select an isolated single-point speed measurement equipment set P(p 1 ,p 2 ,...,p n );

[0033] Among them, the single-point speed measuring device p i is an isolated device, in this embodiment, the isolated device p i It means that there are no other motor vehicle speedometers within 10 kilometers upstream and downstream of the equipment, 1≤i≤n. The specific isolation threshold is set according to the hardware conditions of the speed measuring equipment in the current historical data and the specific conditions of the expressway.

[0034] In this embodiment, the deterrent range of single-point speed measuring equipment is analyzed with the speed measuring equipment and overspeed accident data of 42 national expressways. From 2018 to 2019, there were...
