| 摘 要： | 从车辆动力学入手,分析含有弯度和坡度的路段对车辆行驶的影响,通过对N-S模型的修正得到了适用于弯路和坡路的元胞自动机模型,并且重新定义了弯路和坡路元胞的大小和更新规则。最后用改进的模型进行了仿真实验,仿真结果表明改进的模型能够更好的反映现实交通量之间的关系,证明了应用改进模型对弯路和坡路的仿真研究是可行的。

| Abstract: | Based on vehicle dynamics, the influence of car running on roads with curves and slopes was analyzed. A new cellular automate model which adapted to the road with curves and slopes was derived from N-S model, and the length of every cellular and new renewal rule were also redefined. Employed in the simulation test, the result reveals that the new model can reflect the relationship between realistic traffic quantities and prove the feasibility of the model. |
