PAGE 毕业设计说明书 邯郸市陵园路（光明大街滏河大街段）交通设计 摘 要 本文从城市道路交通设计的视角分析研究道路设计的若干问题，包括：道路横断面形式、车道功能划分、车道宽度、通行能力、公交停靠站以及交叉口的标线与渠化问题。以中小城市交通特点为基础，就城市平面交叉口在渠化设计和信号灯配时等方面所存在的问题进行了分析。介绍了交叉口交通改善设计的主要内容，对其改善设计的方法、原则及步骤作了阐述，并结合邯郸某交叉口交通工程改善实例，指出在道路交叉口处采取一定的交通工程改造措施，有效地增加交叉口的通行能力,充分发挥现状道路系统的交通功能，提高道路交通效率，其研究成果达到均衡路网饱和度,提高交通安全与顺畅性,寻求交通与环境的和谐,提高交通便捷性,充分利用道路的空间资源与交通的时间资源的目的。 关键词 交通设计 交通量 饱和度 延误 通行能力 Abstract Based on the traffic design of the city ,analysis is made of problems in road design ,including the from of cross section , the function dividing of lanes ,the width of lanes , passing capacity ,bus stops, and markings and channelizeion at intersections. The condition of traffic is a significant element to the development of medium or small urban .The major design content for the traffic improvement of intersection is introduced .And combined with practical work in HanDan concrete design method, principle and steps are elaborated .Author points out that the improvement design can effectively increase the traffic efficiency and the traffic capacity for intersection, and make the fully use of the traffic function of present system. It is expected that there will be a harmony between the traffic safety and environment and improvement on road efficiency and service level, balanced network saturation degree, and the fully use of space and time resources of the traffic.
