Embodiment Construction

[0024] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0025] The invention provides a method for quantifying the safety influence range of the congestion charging policy, which can discuss the actual influence range of the congestion charging policy traffic safety on the basis of quantifying the influence of other covariates.

[0026] like figure 1 As shown, a method to quantify the safety impact of congestion charging policy includes the following steps:

[0027] (1) Determine the initial experimental object and initial control object

[0028] Taking the geographical boundaries of the congestion charging policy as the baseline, first select the cells within the congestion charging policy as the initial experimental objects, and the cells outside the charging policy as the initial control objects. The causal analysis model used in this paper recommended by the literature has a sample ratio of 1:1.5 to 1:30 for the init...

Abstract

The invention relates to a method for quantifying a congestion charging policy safety influence range. The method comprises the following steps: (1) determining an initial experiment object and an initial control object; (2) carrying out data acquisition; (3) carrying out score model selection and parameter calibration; (4) determining an experimental object participating in comparison and a matched control object; (5) calculating a safety influence effect; and (6) determining a congestion charging policy safety influence range. According to the method, a unit with basic characteristic attributes similar to those of an initial experiment object in a congestion charging policy safety influence range is selected as an initial control object, the traffic accident numbers in the same time period of the two objects are collected respectively, and the actual influence range of the congestion charging policy is judged based on a proposed cause and effect analysis model. According to the method provided by the invention, the safety influence range of the congestion charging policy can be analyzed by selecting the control object most similar to the experimental object on the basis of quantifying the influence of all attributes.

Description

technical field [0001] The invention relates to the field of road traffic accident safety, in particular to a method for quantifying the safety influence range of a congestion charging policy. Background technique [0002] With the continuous development of traffic patterns, the number of private cars is increasing year by year, resulting in traffic congestion in many cities. In order to reduce road traffic congestion and improve road use efficiency, many countries and cities have begun to implement traffic congestion charging policies in a certain area. The traffic congestion policy has achieved remarkable results in solving road congestion, but with the reduction of vehicles, the speed of roads has increased significantly, and the number of bicycles has also increased significantly, resulting in a significant increase in traffic safety accidents within a certain range. In this context, it is particularly important to reasonably evaluate the safety impact of congestion cha...
