Urban rail line toughness evaluation method considering travel comfort and transportation efficiency

The invention discloses an urban rail line toughness evaluation method considering travel comfort and transportation efficiency, and the method evaluates the toughness of URT lines under large passenger flow and emergencies from the perspective of passenger travel. The passenger travel comfort is considered, an index based on the congestion degree is constructed to evaluate the performance of the line under large passenger flow, the passenger transport efficiency of the line is considered, an index based on the transport efficiency is proposed to evaluate the performance of the line under emergencies, and finally the toughness of the line is evaluated by taking performance loss as an index. Researches taking Chengdu metros as examples show that the operation of lines connecting the center of the Chengdu city and the suburbs of the Chengdu city is seriously influenced by the large passenger flow in the morning peak, and evaluation of the toughness of the lines under the large passenger flow in different runnin
