Evaluation Method of Transport Capacity and Load in Urban Rail Transit System

Abstract

The invention relates to a method for assessing capacity and load of an urban rail transit system, which includes three levels of stations, lines, and line networks, and the evaluation objects cover key facilities such as lines, trains, station platforms, escalators, transfer channels, security checks, and gates equipment and area; select the load degree and full load rate indicators that reflect the supply and demand conditions, and build a capacity load evaluation index system hierarchically; propose a capacity load evaluation method system, including station capacity load, transfer capacity load, line capacity load and The capacity load level evaluation method of the line network capacity load; thus, the present invention aims at the lack of technical means for evaluating the current urban rail transit operation load, and constructs the transport capacity load at three levels of stations, lines, and line networks under different time granularity conditions Evaluation indicators and evaluation methods provide a unified, quantitative, objective and scientific capacity load evaluation technical solution for urban rail transit.

Description

technical field [0001] The invention relates to the technical field of urban rail transit, in particular to a method for assessing capacity and load of an urban rail transit system. Background technique [0002] In recent years, the operation situation of urban rail transit in my country has been generally stable. However, with the continuous increase of newly opened and operated lines, the rapid growth of operation scale, and the continuous increase of passenger traffic, the pressure on the safe operation of urban rail transit is increasing day by day, and the safety guarantee of urban rail transit is becoming more and more difficult. As the industry grows bigger, the service needs and expectations of passengers are getting higher and higher, which puts forward higher requirements for improving the management level of the industry. As more and more cities enter the stage of network operation, accurate assessment of the capacity load of urban rail transit systems is an import...

AI Technical Summary

Problems solved by technology

[0003] At present, the existing methods applied to the operation evaluation of urban rail transit mainly focus on the description of the operation state, which reveals the evolution of the operation situation to a certain extent, but it is difficult for such methods to reflect the interactive relationship between traffic demand and supply, and there is a lack of analysis of the transport capacity. Characterization of load

In addition, some methods use a single indicator to characterize the passenger flow demand, which is difficult to objectively and comprehensively reflect the capacity status of each level of the rail transit system
