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.

摘要： 在城市机动车保有量稳步增长、城市路网结构趋于成熟、公共交通出行分担率低的背景下，城市交通拥堵问题日益严重。总结重庆市交通拥堵特点并分析形成原因，结合国内外先进城市的治堵经验，提出在“多中心、多组团”式发展的重庆应以管理手段为主、建设为辅的发展方式；构建以“公共交通+步行”为主导的出行模式，尽可能在组团内解决居民日常生活、工作、居住等问题，缓解隧道、桥梁的交通压力，在时空上建立和谐的人、车、路、环境之间的关系。
