摘要
本文使用概率统计学方法分析高速公路菱形互通式立交的通行能力,使用交通管理、交通流量学以及汽车安全行驶理论研究菱形互通式立交工程的安全设计。为了更好地将菱形互通式立交应用于实际工程中,本文详细研究了高速公路菱形立交式匝道的技术指标要求,确定高速公路菱形互通式立交匝道屏幕交叉处的合理化设计,最后研究了不同情况之下,计算驶入高速公路左转匝道以及驶出高速左转匝道的通行能力,确定高速公路菱形互通式立交左转匝道的整体通行能力,为高速公路互通式立交布局设计提供数据参考,以提升我国高速公路的整体通行能力。
This paper uses probability statistical method to analyze the traffic capacity of expressway interchanges, and uses traffic management, traffic flow and automobile safety driving theory to study the safety design of diamond interchange. In order to better apply the diamond interchange to the actual engineering, this paper studies in detail the technical requirements of the expressway diamond interchange, and determines the rational design of the intersection of the expressway diamond interchange. Finally, under the different conditions, the traffic capacity of the left-turn ramp and the high-speed left-turn ramp are calculated, and the overall traffic capacity of the left-turn ramp of the expressway interchange is determined, which provides data reference for highway interchange layout design to improve the overall capacity of expressways in China
