| 摘 要： | 在全速度差(Full Velocity Difference, FVD)模型的基础上，提出了一个扩展模型——多速度差(Multiple Velocity Difference, MVD)模型. 在MVD模型中，尝试利用多辆前车信息以提高交通流的稳定性，除了考虑前车与本车的速度差外，进一步利用了多辆前车间的速度差信息. 通过线性稳定性分析，对两个模型进行比较，发现在MVD模型中，自由流稳定的敏感系数临界值变小，稳定区域有明显增加. 数值仿真结果表明，MVD模型能有效地抑制交通流堵塞.

| Abstract: | Based on the full velocity difference (FVD) model proposed by Jiang and Wu, we present an extended car_following model, called the multiple velocity difference (MVD) model. We attempt to enhance the stability of the traffic flow by using the velocity differences of multiple vehicles. It can be found that the critical value of the sensitivity in the MVD model decreases and the stable region is apparently enlarged, compared with the FVD model. Additionally, the simulated results suggest that the MVD model can suppress the traffic jam effectively. |
