摘要以交通流理论为基础，用车速和车流密度来描述车流的运行状态。 - Simulation is used to analysis the tendency of congestion equilibrium and the tendency of congestion level with density change
用数值仿真的方法分析拥挤度随车流密度的变化趋势，及拥挤平衡的变化趋势。 - From the viewpoint of macro dynamic characteristics of freeway traffic flow , this paper classifies the freeway , gives a nonlinear macro dynamic traffic flow model of freeway using density and speed as state variables and then identifies the parameters by using searching approach step by step , finally gives an identification instance
摘要从高速公路交通流的宏观特性和动态特性出发，对高速公路进行了两级分段，以车流密度和车流速度作为状态变量，给出了高速公路非线性的宏观动态交通流模型，进而采用直接搜索法对模型中的参数进行了分段辨识，并给出了辨识实例。
