    摘要:

    为了更加真实地描述在实际交通中的跟驰行为,基于全速度差模型,提出一个考虑车辆机械惯性的跟驰模型。应用线性控制理论给出模型的稳定性条件。与前人提出的模型仿真结果对比,理论结果与数值仿真一致,表明本文提出的模型能够克服前人模型中静止车队启动过程中头车加速度出现瞬间跳跃现象,同时随着车辆机械惯性系数的增加,交通拥堵更加容易发生。

    Abstract:

    In order to describe the carfollowing behavior more actually in real traffic, a new car following model by considering the vehicle’s mechanical inertia effect is proposed on the basis of the full velocity difference car following model. The stability condition is given by applying the control theory. The simulation results are compared with that of the previous models, and show that our model can overcome the deficiency that the acceleration of leading vehicle of motorcade instantly jumps in those models, and the traffic jam can be suppressed as the coefficient of vehicle’s mechanical inertia effect decreases. The simulation results are consistent with theoretical analysis.〖JP2〗
