摘要:
为了更加真实地刻画实际交通现象,基于全速度差(FVD)模型,考虑车辆机械惯性对驾驶行为的影响,提出一种新的跟驰模型.运用系统稳定性理论,得到了交通流保持稳定的条件.数值仿真结果表明:与FVD模型比较,发现提出的模型能克服静止车队启动时头车加速度瞬间跳跃的缺陷,同时,也能更加真实地模拟诸如时走时停等实际交通现象.因此,提出的模型较FVD模型更好地揭示了交通流的演化机理,为车辆智能控制策略的制定提供了一定的理论指导.
Abstract:
In order to describe the traffic phenomena more actually，based on the full velocity difference(FVD)model，a new car-following model，which considers the influence of the vehicle’s mechanical inertiaeffect，is presented. According to the control theory ， the stability condition of traffic system is obtained. Thesimulation results are compared with that of the FVD model. It ’s observed that the proposed model can over-come the deficiency that the acceleration of leading vehicle of motorcade instantly jump，and can simulatemore practical traffic phenomena，such as stop-and-go，etc.. Therefore， the proposed model can describe theactual traffic phenomenon more precisely than FVD model，and support theoretical direction for formulation ofvehicle intelligent control strategies.
