摘要
本文根据道路平面交叉口视距三角形概念以及对通过交叉口设计车速的分析 ,结合成都市规划道路红线宽度和横断面型式等资料 ,利用 CAD技术 ,对成都市道路十字形平面交叉口 ( 75°≤α≤ 1 1 5°)几何特征参数切角取值进行分析 ,形成图表 。
The paper analyses the value to be obtained for the corner cut in the Geometric Characteristics Parameter in Chengdu crisscross road intersection at grade(75°α115°),forms diagrams and tables for reference in accordance with the sign distance triangular concept of road intersection at grade and the analysis of the design vehicle speed through the intersections,at the same time,in combination with the information of Chengdu planned road property width and sectional type etc.,using CAD technology.
