Within the current daily urban life，the public transportation modes include normal pavement traffic and railway traffic. The rational transformation between different modes could realize the maximum of travel efficiency and velocity，with the rail transit hubs as the key nodes. On the basis of fully investigation of the current situation of Peking urban public traffic and rail transit hubs，the major influence and inherent predispositions are well recognized within the paper. Furthermore，the appropriate adjustment countermeasures are approached includes perfecting the connection net and relative traffic facilities within hubs，improving the surrounding connective bordering urban environment with hubs，setting tide lanes according to the site and actual necessitates of hubs，and adjusting the motion pattern planning and setting within the hubs.
