摘要
提出了考虑前方多辆车速度差的多重向前看跟驰模型,利用线性稳定性分析给出交通流演化过程的稳定条件;数值模拟对比几种跟驰模型的稳定特性,考虑前方多辆车相对运动速度可避免出现负速度即车辆倒退的现象,并对车流有很好的致稳作用,得出车流越稳定、附加能耗越低的结论。
An extended optimal velocity model by considering multiple velocity differences ahead is proposed. The condition of the stability has been investigated by linearity stability analytical. Compared the stability of some car following models by means of numerical methods ,the result shows that the collision between successive cars can be removed via introducing multiple velocity difference. Then the additional energy consumption in stable region and the consumption energy in unstable region are discussed respectively.
