Abstract: With the steady growth of motor vehicles in the cities， mature urban road network structure and in the context of public transport share rate， there appears the growing problem of urban traffic congestion. On the basis of summarizing the characteristics of traffic congestion in Chongqing， this paper analyzes the reasons for its formation， and proposes that the “multicenter， multigroup” development of Chongqing should be based on “public transportation + walking”. As far as possible， the problems of daily life， work and residence of residents in the group should be solved， the traffic pressure of tunnels and bridges be eased， and a harmonious relationship between people， vehicles， roads and environment in time and space be established.

Key words: traffic engineering, traffic congestion, public traffic
