基于全速度差(full velocity difference,FVD)模型,考虑多车信息对跟驰车的影响,提出了一种改进的多期望速度与速度差(multi-anticipative velocity and velocity difference,MAVD)模型。通过线性稳定性分析,获得改进模型的稳定性条件,有效增加了交通流的稳定区域。改进模型的运动延迟时间和启动波速更接近实测值,也不产生过高加速度。数值模拟结果进一步表明,改进模型通过考虑多车信息,可以克服FVD模型中低反应系数时出现的负速度的缺陷。
Based on the full velocity difference (FVD) model and considering the effect of multi-car information on the car, an improved multi-anticipative velocity and velocity difference (MAVD) model is proposed. Through the linear stability analysis, the stability condition of the improved model is obtained, which effectively increases the stable area of the traffic flow. The improved model’s motion delay time and start-up wave speed are closer to the measured value and do not produce too high acceleration. The numerical simulation results further show that the improved model can overcome the shortcoming of negative velocity in low response coefficient in FVD model by considering multi-vehicle information.
