混合车流三大参数关系的计算机仿真

Study on the Relationship of Flow Speed Density of Mixed Traffic Flows

以我国混合车流作为高等级公路交通流的基本构成，分析混合车流的交通特性，采用实地采集数据和计算机模拟仿真相结合的手段，得到了不经换算的混合车流条件下不同交通总量和不同车型比例速度、密度和流量三大参数的偌模图。

The characteristic of mixed traffic flows is analyzed by taking mixed traffic flows as the basic situation of traffic flows of highways in China. Amonograph describing the relationship of flow speed density for different type of vehicles and mixed traffic flows is obtained by computer simulations and the data collected in situ for which conversion is not necessary.
