With the process of urbanization and motorization speeding up,many cities build up rail transit to solve the urban transportation problems,such as traffic congestion,pollution,energy crisis,etc.How to improve the transfer efficiency of urban rail transit and transfer service distance becomes one of traffic problems after urban rail transit is set up.Based on the Xi'an rail transit development planning,the methods of the bicycle and rail transit transfer are studied after Xi'an rail transit plan was put into practice.The preliminary planning about transfer sites of Xi'an bicycle and rail transit transfer is also made.The seamless connection between rail transit and bicycle traffic in Xi'an has been realized.Thus,the urban rail transportation convenience and urban rail transit transfer efficiency are improved.
