摘要
考虑多辆前导车信息对跟驰车的影响,提出了一种改进的交通流跟驰模型.通过线性稳定性分析,得到了改进模型的稳定性条件,改进模型通过调节多前导车信息,使交通流的稳定区域明显扩大.通过非线性分析获得不稳定区域下的扭结-反扭结密度波.数值模拟表明多前车信息对交通流存在不可忽视的影响.
With the consideration of the information's effect of the multiple leading cars to the following car, an improved car-following model of traffic flow has been deduced. The linear stable judging condition is obtained for the improved model by its stable analyzing, which shows the stable range of the improved model is enlarged obviously by adjusting the information of the multiple leading cars. The kink-antikink density wave is attained in unstable range for the model by nonlinear analysis. Numerical simulation shows that there is unavoidable effect to traffic flow from the multiple leading cars' information.
