It is widely used in urban traffic planning, traffic operation and macro regulation. The traditional car following model of traffic flow considering the main parameters of a vehicle, the driver factors not enough attention, this paper introduces the driver from the perspective of Full Velocity Difference (FVD) model of extended model based on FVD model, combined with the driver’s visual effect, the stability of traffic flow characteristics of extended model of linear stability analysis. The influence of vehicle shape parameters on the stability of traffic flow is analyzed by quantizing the driver’s angle of view with the body parameters of the driving vehicle. The simulation results show that the extended model in the case of smaller car traffic flow stability is better than the FVD model; the coefficient of sensitivity to the changes of view driver is high, the traffic flow is more stable; the higher the probability of driver’s visual, traffic flow is more stable; for large vehicles, traffic during the peak period for its development lane can improve the phase stability of traffic flow. %K 交通工程 %K 交通流稳定性 %K 线性分析 %K 视觉角度 %K 后视效应< %K br> %K traffic engineering %K stability of traffic flow %K linear analysis %K visual angle %K backward looking %U http://jdxb.bjtu.edu.cn/CN/abstract/abstract3403.shtml
