Abstract: In order to enable passengers to quickly find entrances and exits in urban rail transit stations,reduce ticket purchasing time and avoid errors in travel routes, this article studied an electronic guidance system of urban rail transit. Thearticle analyzed the advantages of electronic guidance system, and designed the architecture based on the functions of passenger information system.Through the implementation of the front-end information display and publishing, guidance network management platform and system security, the feasibility of electronic guidance system architecture was verified.The realization of electronic guidance system solves many problems of traditional guidance function and provides technical support for the convenience of passenger information system.
