摘要
引入超车换道流量,建立了混合交通流的连续性方程;通过对交通流参数的微分变换,建立了混合交通流的运动微分方程.连续性方程和运动微分方程构成了混合交通流的动力学模型.将模型应用于无超车换道交通流,求出了流量和密度之间的关系.结果表明在低密度段模型与实测数据吻合.
Considering the overtaking flow, this paper built the continuum equation of mixed traffic flow, set up the kinematics differential equation by means of differential calculus. The continuum equation and kinematics differential equation composed the dynamic model of mixed traffic flow. When the model is applied to traffic flow without overtaking flow, the flow-density relationship is obtained. The results indicate that the model coincides with the surveyed dates.
