Research on RITS universal technology platform is to realize the effective management, share spatial
data and non-spatial data, and change the situation of “information lonely island” in the existing railway
information system. Universal technology platform is composed of the train positioning system, the
communication system, railway information sharing platform and railway basic geography database. The key
technologies involved in RITS universal technology platform include train position technology, communication
technology, data sharing and comprehensive technology, and railway geographic information system etc. Finally
the comprehensive safety monitoring system of the Chinese Qinghai-Tibet Railway is introduced as an example.
