混合车流基本交通流特性描述是混合车流理论研究的基础。分析了未来我国高等级公路车型结构 ,界定混合车流研究的合理范围 ;提出描述混合车流运动自由度的随机度和相互影响的粘度两个基本概念 ;通过理论计算和实地测定得到混合车流的速度模型和堵塞密度。
Hybrid traffic flow The basic traffic flow characteristics description is the basis of the theory of mixed traffic flow. The paper analyzes the reasonable structure of the study on the structure of high-grade highway in China in the future and defines the research scope of the mixed traffic flow. Two basic concepts of describing the random degree and the mutual influencing viscosity of the mixed traffic flow motion are proposed. The velocity model of the mixed traffic flow is obtained through theoretical calculation and field measurement And plugging density.
