Abstract: This paper introduced a new generation of railway ticketing and reservation system. Based on a largeamount of data accumulated during the construction and operation of the new generation of railway ticketing andreservation system, such as system operation and business operation, a big data platform for railway passengertransport was constructed by combining key technologies of distributed data storage and computing framework, realtime flow computing analysis, big data visualization technology. It was implemented the big data application innovationof intelligent ticket pre-allocation, users portrait of railway passenger and passenger transport operation support. Thepaper put forward the direction of further research on railway passenger transport big data in expanding the scope ofapplication of railway passenger transport business, improving passenger travel experience, and constructing the trafficbig data business ecosystem.
