Through calculation of adjacency matrix, it concludes the r e p r transfer method with reducing middle links of transfer. The transfer example o F. transfer between the 1st subway and bus in the city of NanJing verifies the arithmetic E C is validated.

It is effective to o y build comprehensive passenger transportation system characterized as follows: with r t s railway transportation acting skeleton and buses acting main body. Now the method e r o F is adopted in many large cities, and maybe develops as a trend of urban public g n transportation system. People have to transfer between different vehicles because i j n a people cant arrive in destinations by one
