Problems solved by technology

However, it should be noted that the participation of a large number of mixed control objects (that is, the road safety difference with the experimental objects in the same external environment) will greatly reduce the effectiveness of the evaluation model, thereby affecting the analysis results

Embodiment Construction

[0029] Embodiments of the invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0030] Such as figure 1 As shown, it is a method for eliminating the influence of mixed control objects proposed by the present invention, which includes the following steps:

[0031] Step 1. Screening of experimental objects and initial control objects. Road sections that implement road safety measures (such as road speed limits) are experimental objects, and road sections that do not implement road safety measures are initial control objects. In order to ensure that each experimental object can be matched to the optimal To control the subject optimally, the sample ratio of the experimental subject to the initial control subject is recommended to be 1:10;

Abstract

The invention discloses a method for eliminating influence of hybrid control objects, which comprises the steps of: firstly, selecting experimental objects with safety measures and control objects without safety measures, and respectively investigating the road accident quantity and safety influence factors of the experimental objects and the control objects; secondly, determining final control objects based on the safety influence factors and a matching method; and finally, establishing a safety analysis model based on the initial control objects and the final control objects to check the effectiveness and accuracy of the method. According to the method, the control objects comparable to the experimental objects are found through a score calculation model to construct a safety accident analysis model, so that the influence of human subjective consciousness is greatly reduced, and a relatively accurate and reliable safety evaluation result is obtained.

Description

technical field [0001] The invention relates to a method for eliminating the influence of mixed control objects, which belongs to the technical field of traffic safety. Background technique [0002] With the development of society and economy, the number of cars in the society continues to increase. At the same time, the incidence of road safety accidents also continues to increase. Therefore, how to reduce the occurrence of road accidents has become the focus of research in the field of transportation in recent years. In order to reduce the occurrence of road traffic accidents, many traffic safety management measures have been implemented in various cities, such as road speed limit signs, road fixed-point speedometers, etc. The road system is a complex system consisting of four subsystems of "people-vehicle-road-environment", and each subsystem contains many influencing factors. Generally speaking, the change of each factor may lead to the occurrence of traffic accidents, ...
