在对城市道路上车流运行的机理进行微观分析的基础上，提出了自由流随机度的概念，并用以衡量车流中车辆相互影响的大小；同时，通过实测数据和理论分析，建立了城市道路上车队离散过程中随机度随路段变化的数学模型；最后得到了适用于城市道路车队离散过程中的交通流模型．
On the basis of the microscopic analysis of the mechanism of traffic flow on urban roads, the concept of free flow randomness is proposed and used to measure the mutual influence of vehicles in traffic flow. At the same time, based on the measured data and theoretical analysis, The randomness of the team during the discrete process changes with the road section of the mathematical model; finally obtained suitable for urban road fleet in the process of discrete traffic flow model.
