摘要:为了优化道路横断面、提高道路通行能力、节约土地资源,在分析现有机动车道宽度设计标准及国内外发展趋势的 基础上,以窄机动车道在杭州市道路综合整治工程中应用为例,通过交通量调查、EMME/2 交通软件模拟和驾驶人问卷调 查分析窄车道的使用效果。结果表明,适当压缩车道宽度可 提高路段、交叉口及整个路网的通行能力,降低交叉口的饱和度及车均延误,同时减少驾驶人的变道行为,提高行车安全性。窄车道的成功应用为编制《城市道路机动车道宽度设计 规程规范(浙江省工程建筑标准)》提供了范例和借鉴。

Abstract:To optimize road cross-section, enhance roadway capacity, and fully utilize land use resources, this paper discusses the application of narrow lane in road upgrading project in Hangzhou City based on an analysis of existing design specification and review of narrow lanes' usages in China and abroad. Through surveying traffic volumes and drivers attitude on narrow lane, the paper evaluates the traffic performance with a planning software called EMME/2. The result of the study indicates that properly reduced lane width can improve the capacity of roadway network (intersections and segment alike), decrease degree of saturation at intersection, reduce traffic delay, and avoid illegal lane change hence improving traffic safety. The successful application of narrow lane in Hangzhou provides the evidence for the preparation of a specification named Lane Width Design for Urban Roads.

Keywords:traffic engineering; the width of narrow lane; roadway capacity; application effect
