| 摘 要： | 在只考虑前面车流的交通流格子模型的基础上,充分考虑后面车流以及相关车流的作用,提出一种新的交通流格子模型. 应用线性稳定性理论进行分析,得出车流的稳定条件、亚稳态条件及不稳定条件. 通过加强后面车流和相关车流的作用,交通流的稳定性得到了提高.数值模拟对比了几种格子模型的稳定特性,结果表明考虑后面车流及相关车流的模型能够增强系统稳定性,有效抑制交通阻塞的发生.

| Abstract: | Abstract: The forward looking lattice model of traffic flow is extended to take the backward looking effect and the relative current effect into account. The stability, neutral stability and instability conditions are obtained by the use of the linear stability theory. The stability of the uniform flow is strengthened due to the effects of the backward looking and the relative current. The performances of several traffic flow models are investigated analytically and numerically. The results indicate that by increasing the strengths of the backward looking effect and the relative current effect, the stable region increases and the traffic jam is effectively suppressed. |
