摘　　要：解决城市交通拥堵的关键是深入理解城市交通拥堵的形成机理与演变规律,从而制定科学的管理控制策略.本文首先介绍了城市交通拥堵基本概念,以及城市交通拥堵传播规律与消散策略的最新研究进展,在此基础上重点介绍了本课题组在城市交通拥堵传播规律与消散控制策略方面的研究成果.包括采用微观与宏观相结合的方法建立拥堵传播模型,分析突发事件所导致交通拥堵传播规律,交通需求增长所导致拥堵瓶颈识别,提出动态拥堵消散控制策略.The key issue to solve urban traffic congestion is that deeply understanding the mechanism for traffic congestion formation and evolution,then make scientific manage and control strategy.In this paper,some basic concepts for urban traffic congestion,and the progress on studies for urban traffic congestion propagation and dissipation control strategies are firstly given,then the works by our group in urban traffic congestion propagation and dissipation control strategies are mainly introduced.It includes establishing the congestion propagation model by combine the micro and macro methods,analyzing the formation and evolution law of urban traffic congestion induced by accident,identifying the congestion bottleneck with high traffic demand,proposing dynamic congestion dissipation control strategies
