桂丹路交通工程设计 摘 要 随着城市道路的交通构成变化的发展，人们对交通工程设计的要求也越来越 高，道路设计中安全合理、舒适、人性化理念越来越重要。 本文针对桂丹路，从交通设计的视角分析研究道路设计的若干问题，包括： 路段交通工程设计，协调道路横断面形式、车道宽度、设计车速、公交停靠站以 及交叉口的标线与渠化问题。然后以桂丹路和联星大道交叉口为例，基于交叉口 机动车流量的数据分析详细阐述了交叉口信号配时的计算。并以此为基础，在综 合分析该路段交通特点的基础上较为系统、详尽的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、原则及步骤作了进一步的阐述，并结合桂丹路 和联星大道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，能有效地减少延误，增加交叉口的通行能力。 本文研究成果能够均衡路段饱和度，提高交通安全与顺畅性，对于提高道路 的利用效率和服务水平，改善城市的整体风貌，促进城市发展，修编城市道路设 计规范皆具有重要的实用意义和参考价值。 关键词：交通工程； 设计； 交叉口； 信号配时； 交通标志标线 I Communication Engineering Design of Guidan Road Abstract Along with the development of city traffic form produced tremendous changing， the requirements of communication engineering design for people are also increasing, such as: road safety in the design reasonable, comfortable, humanistic philosophy is each designers pursuit of the goal. Based on the traffic design, analysis is made of problems in road design, including the from of cross section ,the width of lanes, design vehicle speed, 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 traffic improvement of intersection is introduced. And combined with the crossings of Guidan road and Lianxing road, principle and steps are elaborated Author points out that the improvement design can effectively decrease delay, increase the traffic capacity for intersection. It research result can balanced network saturation degree, exaltation traffic safety with sm th, the study is of great practical importance and reference value in improvement on road efficiency and service level, improvement city of who
