Urban rail transit system transport capacity load assessment method

Abstract

The invention relates to an urban rail transit system transport capacity load assessment method, which comprises three levels of stations, lines and a line network, and assessment objects cover key facilities, equipment and areas such as lines, trains, station platforms, building escalators, transfer channels, security inspection and gates. The method includes selecting load degree and load factor indexes reflecting supply and demand conditions, and constructing a transport capacity load evaluation index system in a layered manner; and providing a transport capacity load evaluation method system, which comprises a station transport capacity load grade evaluation method, a transfer transport capacity load grade evaluation method, a line transport capacity load grade evaluation method and a line network transport capacity load grade evaluation method. Therefore, aiming at the problem of lack of urban rail transit operation load assessment technical means at present, the invention constructs the transport capacity load assessment indexes and assessment methods in three levels of stations, lines and wire networks under different time granularity conditions, and provides a unified, quantitative, objective and scientific transport capacity load assessment technical scheme 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
