doi:10.3969 /j.issn.1674-0696.2013.02.16

Abstract

Abstract: Aiming at current status of the road safety situation，the common design problems of mountainous urban arterial road and the running condition corresponding of representative roads are studied from the plan and vertical design standards，cross-section and lane width，intersection control，and ancillary detail design. Finally，the main control principle of urban arterial road design in mountainous city is put forward; meanwhile，the design technical gist is also set out.

Key words: horizontal and vertical alignment, road width distribution, intersection, median strip

摘要： 针对当前道路交通安全状况现状，从山城主干道设计的平纵设计标准、横断面与车道宽度、交叉口控制、附属细节设计等方面入手，对山地城市主干道常见设计问题与代表性道路的运行状况进行对应研究，提出了山城主干道设计的主要控制原则，阐述了安全设计技术要点。

关键词: 平纵线形, 路幅分配, 交叉口, 中央分隔带
