A Digital Twin Framework and an Implementation Method for Urban Rail Transit

As an important part of urban transportation, rail transit impacts the travel, work and life of urban residents. In order to improve the intelligence of the whole life cycle of urban rail train, the concept of digital twin is introduced into the application of rail train, which is used to guide the design, optimize the production plan, improve the quality and improve fault prediction ability for the trains. However, the existing digital twin technology is mostly used in aircraft, automobile and other industries, and the applications on the urban rail transit are mostly focus on local systems. In order to solve the above problems, this paper proposes a digital twin framework for the urban rail transit and its implementation method to guide the creation of digital twin of rail transit.
