| 摘 要： | 由于缺乏城市道路交叉口合理角间距的标准,经常存在因角间距过小造成交通秩序混乱,导致交叉口通行能力严重降低。引用接入管理理论,在分析交叉口功能区长度的基础上,分别对不同类型的角间距进行计算,得到了不同条件下城市道路交叉口合理角间距的推荐值,为科学合理设置交叉口附近的接入道路提供了定量依据,有利于交叉口的畅通与安全。

| Abstract: | The traffic capacity of intersections is usually seriously reduced by the lack of standards on reasonable angle spacing of urban road intersection and traffic chaos caused by too small pitch angle.The theory of Access Management is based on analysis of the length of functional areas in intersection.By calculating different types of angle spacing distance under different conditions,it provides a quantitative basis for the smooth flow and security in intersections. |
