| 摘 要： | 为体现不同车辆在交通流中的差异性．在Nagel—Schreckenberg模型的基础上，将减速概率与车辆密度和速度联系起来．提出了一种改进的一维元胞自动机交通流模型．重点研究了平均速度与流量的关系并与实测结果进行了比较．讨论了交通堵塞形成的过程。数值模拟结果表明本文模型在速度-流量关系的描述上耍优于Nagel—Schreckenberg模型。 |

| Abstract: | In order to embody the difference of each vehicle in the traffic, an improved one-dimensional cellular automaton traffic model, whose deceleration probability is depend on the density and the speed, is proposed based on the Nagel- Schreckenberg model. Laid an emphasis on the study of the relation between the average velocity and the flow and compared with the experiment, the process of jam has been discussed. Numerical simulation results show that the present model depicts the speed-flow relationship better than that of the Nagel-Schreckenberg model. |
