Research on Standardization Scheme of Operation Capacity Calculation for Urban Rail Transit Lines

Abstract

Due to the lack of unified standards, the existing software for calculating the operation capacity of various urban rail lines introduces many problems to the design and implementation of urban rail engineering. Based on the full grasp of the structure characteristics of urban rail line, train traction and braking characteristics, signal system performance and operation management law, and according to the requirements of urban rail transit system engineering design, this paper puts forward standardization scheme of urban rail transit line operation capacity calculation, involving standard principles, operation capacity indicators and accuracy requirements, normalized computing framework, standardized model interface, application and scalability. This paper proposes a standardized process and modeling scheme of line operation capacity calculation, which is convenient for the project owner and all participants to evaluate the train operation capacity achieved by the urban rail transit system design scheme (such as line design scheme and signal design scheme), so that the deviation between the calculation results and the actual effect after the implementation of the scheme is within the allowable error range, all parties can reach a consensus on the driving capacity status and optimization direction of the project scheme, so as to optimize the scheme as soon as possible in the early stage of project design and improve benefits.
