基于汽车、自行车和行人组成的异质性交通流的特性，本文提出了考虑摩擦效应的三种个体跟随模型，其中个体可统一称为汽车、自行车或行人。利用微观变量和宏观变量之间的关系，建立了考虑摩擦效应的异构交通流动态模型。分析和数值结果表明，自行车摩擦效应会降低汽车流量和速度，行人摩擦效应会降低自行车流量和速度，但这种降低与自行车和行人密度有关。
Based on the properties of the heterogeneous traffic flow consisting of car, bicycle and pedestrian, we in this paper present three individual-following models with the consideration of the friction effects, where the individual can here be referred to as car, bicycle or pedestrian in a unified manner. Using the relationship between the micro and macro variables, we obtain a dynamic model for heterogeneous traffic flow with the consideration of the friction effects. The analytical and numerical results show that the bicycle friction effect will reduce the car flow and speed and that the pedestrian friction effect will reduce the bicycle flow and speed, but the reductions are related to the bicycle and pedestrian density.
