为了对信号交叉口上游车辆换道行为进行分析,以元胞自动机交通流理论为基础,结合自由换道模型及强制换道模型提出了进口道附近路段的综合换道模型,并对原有强制换道模型进行改进.通过对综合换道模型进行模拟,得出进口道附近交通流的时空关系及密度关系图.模拟结果表明,车流密度在[0,0.2]及[0.4,0.6]范围时,进口道换道率变化率较高;同时在中低密度下,随着换道率的增加,平均车速逐渐降低,但在高密度下,车速随换道率变化并不显著.
In order to analyze the lane changing behavior of the vehicles upstream of the signalized intersection, a comprehensive lane changing model of the road near the inlet is proposed based on the cellular automata traffic flow theory, combined with the free lane changing model and the forced lane changing model, Forced lane change model is improved.Considering the comprehensive lane change model, the spatio-temporal relationship and density diagram of the traffic flow near the entrance are obtained.The simulation results show that the traffic density is in the range of [0,0.2] and [0.4,0.6] , The rate of change of lane change rate is higher. At the same time, with the increase of lane change rate, the average speed decreases gradually with medium and low density. However, the change of speed with lane change is not significant at high density.
