【摘要】:在分析車輛經過山區(qū)高速公路彎道、縱坡上坡的交通流特點和山區(qū)高速公路速度限值所受到的各種影響因素的基礎上,應用元胞自動機理論建立山區(qū)高速公路彎道、長坡的某路段的微觀交通流模型,運用仿真實驗分別確定彎道路段最優(yōu)速度限制值和長坡路段最優(yōu)速度限制值,并提出設置路面物理設施和路側電子設施與速度限制措施相結合的速度限制設計內容。
[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.
