【摘要】：在分析车辆经过山区高速公路弯道、纵坡上坡的交通流特点和山区高速公路速度限值所受到的各种影响因素的基础上,应用元胞自动机理论建立山区高速公路弯道、长坡的某路段的微观交通流模型,运用仿真实验分别确定弯道路段最优速度限制值和长坡路段最优速度限制值,并提出设置路面物理设施和路侧电子设施与速度限制措施相结合的速度限制设计内容。
[Abstract]:On the basis of analyzing the characteristics of traffic flow and the factors affecting the speed limit of highway in mountainous area, the paper establishes the curve of expressway in mountainous area by using cellular automata theory. The microscopic traffic flow model of a section of a long slope is used to determine the optimal speed limit value of the bend section and the optimal speed limit value of the long slope section by simulation experiments. The paper also puts forward the design content of speed limit by setting pavement physical facilities and road side electronic facilities combined with speed limiting measures.
