Based on these data,it reveals the problems concerned with public transportation transfer,such as weak link of different travel modes,long transferring distance,inconvenience and the other derived problems.

Public traffic transfer inquiry system based on the note platform;

On the basis of the analysis of the common algorithm of public traffic transfer,the priority algorithm in the fewest transfer times is presented,and the inquiry note platform of public traffic transfer based on the technology of GSM short messages is constructed.

Through analyzing many shortest path algorithms in transit network, according to the characteristic of public traffic transfer matrix, a new standard algorithm is proposed to find an optimal path in transit network.

Secondly,based on the shortest path algorithm,a public traffic network-transit matrix and a non-transfer matrix are introduced to design the public traffic transfer algorithm.
