Division of Risky Sections of Railway External Environment Based on TOPSIS

Abstract

With the rapid development of economy and society, the external environmental problems of railways have become more and more prominent, and external environmental accidents have occurred from time to time. The external environmental problems along the railway have become more and more prominent, which has become one of the important risks that endanger railway safety and affect the order of trains. By analyzing the external environmental risk profile, quantifying the impact of different types of hidden danger points along the line, dividing the hidden danger section of the line, dividing the risk section, and carrying out special rectification of the sections with different risk levels, it will be conducive to efficient and centralized rectification of the external environment and improve environmental governance Efficiency and risk control level.
