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] Such as 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 i...

Abstract

The invention relates to a method for quantifying the security impact range of a congestion charging policy, comprising the following steps: (1) determining the initial experimental object and the initial control object; (2) data collection; (3) scoring model selection and parameter calibration; (4) Determine the experimental objects participating in the comparison and the matching control objects; (5) Calculation of the safety impact effect; (6) Determination of the safety impact range of the congestion charging policy. The present invention selects units with similar basic characteristics and attributes as the initial control objects to the initial experimental objects within the safety influence range of the congestion charging policy, respectively collects the number of traffic accidents in the same time period of the two, and judges the congestion based on the proposed causal analysis model The actual scope of influence of the charging policy. The method proposed by the invention can analyze the security impact range of the congestion charging policy 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...
