Verification of metro track signalling layout based on microscopic simulation

Nowadays the trackside equipment layout of the traditional urban rail transit signal system mainly depends on the personal experience of the system designer. The accuracy and efficiency of the work cannot be guaranteed, relying more on the field test in the future. This paper focuses on this problem existing in the design work of signal system, based on the completeness and compatibility of the signal system design, establishes a signal simulation model of Hefei rail transit line 1, and the signal system inspection rule base of design, the line 1 signal system layout verification, find out the potential of the design scheme of design factors to the safety of driving, ensure quality of the design of signal system, improve the operation of the system safety reliability and availability.
