In view of these outstanding problems, according to the mainstream ticket system mode and technical system of railway and urban rail transit, this paper mainly analyzed the advantages and disadvantages of different ticket systems and the key points of operation organization, provided an integrated integration technology scheme in combination with the current implemented cases, and discussed and put forward the integration technology ideas, key problems and solutions of different ticket systems of railway and urban rail transit.
