相变

The paper presents a classification of six typical traffic states based on real-detected data and traffic flow model,and then an introduction of the definition and identification method of "state transition" to explain congestion mechanism.A comparison is conducted between "State transition" and B S Kerner's "phase transition",and an analysis is made of its characteristics at different sections and in different hours.

基于实测数据和交通流模型，划分了六种典型交通状态，提出了"状态跳转"的概念及判别方法以解释拥挤机理；对比了状态跳转与B S Kerner的"相变"理论的差异及其随路段、时段的变化规律；最后给出了拥挤阈值的定义、指标、确定方法，分析了影响因素及与交通控制的关系。
