干线一级公路交通组织设计研究

现有部分一级公路功能与交通需求不相匹配、平面交叉和出入口布设密集、路段和交叉口的交通组织不甚合理，导致公路通行效率较低、道路安全性较差。以上海市大叶公路为例，对干线一级公路交通组织进行了设计研究，基于公路的功能定位选用相适应的技术指标，通过合理的一般路段与平面交叉口交通组织设计以及指路标志设计，提升了公路的整体运行效率和交通安全，并为后续干线一级公路的建设提供了一定的工程经验和设计参考。

Study on Design of Traffic Organization for Trunk First-class Highway

The functions of some existing first-class highways do not match the traffic demand, the grade crossings and entrances are densely arranged, and the road sections and intersections are lack of scientific and reasonable traffic organization, resulting in the low traffic efficiency and poor road safety. Taking Daye Highway as an example, the traffic organization of the trunk first-class highway is designed and studied. Based on the functional orientation of the highway, the appropriate technical indicators are selected. Through the reasonable traffic organization design of general road sections and intersections and the design of guide signs, the overall operation efficiency and traffic safety of the highway have been improved, and the certain engineering experience and design reference are provided for the subsequent construction of the trunk first-class highway.
