面向交通改善的道路典型设计要素研究——以辽宁省大连市交叉口为例

构建美好出行愿景,提高城市生活品质和出行品质已成为大中城市近年来发展的主要方向。出行品质与城市道路品质密切相关,面向交通改善与道路品质提升,需处理好城市平面交叉口通行效率低等问题。本文通过分析国外交叉口的设计要素改善,提出从典型设计要素入手提升我国交通设施供给品质。并以辽宁省大连市软件园路和数码路的交叉口为研究对象,针对现状问题通过改善两种道路典型设计要素来优化平面交叉口,运用VISSIM交通仿真软件对改善前后的交叉口进行模拟实验分析,论证优化道路典型设计要素的可行性。

Building a vision of beautiful travel and improving the quality of urban life and travel quality has become the main direction of the development of large and medium-sized cities in recent years.Travel quality is closely related to the quality of urban roads.For the improvement of traffic and road quality,it is necessary to deal with the problem of low traffic efficiency at urban intersections.By analyzing the optimization of design elements in foreign intersections,this paper proposes to improve the supply quality of transportation facilities in China from the typical design elements.Taking the intersection of Ruanjianyuan Road and Shuma Road in Dalian city,Liaoning Province as research object,two typical design elements of roads are improved to optimize the level intersection to address the current issues.VISSIM traffic simulation software is used to conduct simulation experiments and analyze the intersection before and after the improvement,demonstrating the feasibility of optimizing typical design elements of the road.
