Embodiment Construction

[0024] In order to enable those skilled in the art to better understand the solution of the present invention, the specific implementation method of the technical solution will be further described in detail below.

[0025] 1) Road traffic safety evaluation algorithm

[0026] Road traffic safety evaluation, that is, to quantify the road traffic safety status levels in different regions through the analysis of a large amount of historical data. This is a typical fuzzy classification problem. Therefore, the present invention uses a fuzzy clustering algorithm to analyze the obtained data and conduct research on related problems.

[0027] Wherein, the present invention mainly considers the following factors when selecting the feature index:

[0028] (1) Consider the difficulty of data acquisition corresponding to this indicator;

[0029] (2) Considering that this indicator can reflect the influence of people, vehicles, roads and environment on traffic safety in decision-making; ...

Abstract

The invention discloses a road traffic safety evaluation method. Road traffic safety levels are evaluated from multidimensional angles by selecting ten feature indexes on the basis of road traffic accident statistic data. The road traffic safety evaluation method based on the fuzzy C average value clustering is provided for determining the road traffic safety levels, a road traffic safety level division model suitable for an area level is established, the area difference is adjusted by designing an area diversity coefficient, and the provided method can divide the road traffic safety levels in an area, and evaluate the road traffic safety level in the area.

Description

technical field [0001] The invention relates to the field of road traffic, in particular to an evaluation method for road traffic safety. Background technique [0002] The problem of road traffic safety has gradually attracted people's great attention. Strengthening road traffic safety management and improving road traffic safety is an important task of the national road traffic operation management department. The management department needs a method to objectively evaluate the road traffic safety level of each region, determine the road traffic safety level of each region, and allocate limited resources reasonably to support the areas that need to improve road traffic safety conditions, so as to make appropriate decisions resource allocation scheme. [0003] However, it is extremely complicated to evaluate the road traffic safety level in different regions, and based on different indicators, completely different evaluation results may be obtained. Taking the data in the ...
