Research on Simulation Testing Technology for Urban Rail Transit CBTC Systems

The design and implementation of an automatic operation system for urban rail transit is a crucial topic in the construction of smart cities. This project developed an advanced automatic operation system, covering core modules such as interlocking systems, onboard ATP, ground ATO, and simulation running diagrams. Using a distributed architecture, the system supports efficient simulation and control of large-scale line networks. After multiple rounds of testing and optimization, the system's performance was significantly improved, with a processing capacity of 48,000 requests per second and a response time of 18ms. Field tests on actual lines showed that the system's reliability reached 99.99%, significantly improving operational efficiency and safety. This achievement provides important support for the intelligent development of urban rail transit.
