Embodiment Construction

[0023] In order to make the above objects, features and advantages of the present invention more obvious and comprehensible, the present invention will be further described in detail below in combination with relevant theories and specific implementation methods used.

[0024] In the 1970s, Saaty, an American operations researcher, proposed the famous Analytic Hierarchy Process (AHP) for many evaluation objects with diverse attributes and complex results, making it difficult to fully adopt quantitative methods. When using the AHP method for evaluation and decision-making, it can be roughly divided into the following steps.

[0025] 1) Analyze the relationship between the basic elements in the evaluation system, and establish the hierarchical structure of the system.

[0026] 2) Make a pairwise comparison of the importance of each element of the same level with respect to a certain criterion in the previous level, and construct a pairwise comparison judgment matrix.

Abstract

A method of evaluating safety status of a railway level crossing includes: for the railway level crossing, analyzing probable factors of accidents occurring at the railway level crossing, and organically combining the extension principle, set pair analysis and hierarchical analysis to evaluate the safety status of the railway level crossing; dividing the factors into two levels by hierarchical analysis, and performing calculating to determine weights of two levels of indexes; scoring the railway level crossing through experts, and determining safety levels of the factors on the basis of the extension principle; according to the weights of the factors and their safety levels, and analyzing the safety status of the railway level crossing under the action of the factors, according to the principle of set pair analysis.

Description

technical field [0001] The present invention relates to The field of railway traffic safety, especially involving the use of safety evaluation methods to evaluate the safety status of railway and urban road level crossings. Background technique [0002] A railway level crossing is a place where railways and roads cross each other on the same level. In the process of collecting and analyzing the attribution of responsibility for railway accidents that have occurred over the years, it is found that more than 90% of the accidents cannot be directly attributed to the railway authorities (travel accidents without responsibility), that is, they are obviously caused by the negligence of non-railway employees The driving accidents that cause account for the vast majority. In 2008, a total of 149 railway traffic accidents occurred in Liaoning Province, resulting in 126 deaths. Among them, 142 accidents were caused by pedestrians or vehicles rushing over the railway line, acco...
