To take full advantage of urban rail transit (URT), it needs the cooperation of bus from capacity, station spacing, network, and hub. The compute method to match transport capacity was brought forward. In addition, based on minimal traveling time, the optimum station spacing between bus and URT was determined. And the guiding principles are formulated for the restructuring and optimization of the networking system for public buses and URT. Finally, hubs between URT and bus were classed three sub-grades, and their layout was planned, and the design method of transfer channels method was proposed.
