城郊高速公路出口匝道落地点的选位方法

提出了一种基于接入管理技术的城郊高速公路出口匝道落地点的选位方法以提高高速公路主线和地面道路交通流的畅通与安全性. 对从出口匝道接入周围的土地利用类型、地面道路和上下游交叉口的功能与等级进行了分析,确定了落地点的宏观选位方法;以此为基础,从落地点与上下游交叉口的接入窗口、接入间距和接入顺序3个方面进行了探讨,对落地点的选位进行了微观界定. 研究表明本文提出的出口匝道落地点的选位方法简单,可操作性强.

Research on Locating of Suburban Freeway off Ramp-Street Terminal

To improve traffic efficiency and safety of freeway main segment and the connected roads, a method on locating of suburban freeway off ramp-street terminal was proposed. Based on analysis of land use within off ramp area, connected roads, function and category of access streets and the intersections, a macroscopic terminal locating method was studied. The recommended microscopic terminal locating approach was established considering access window, access spacing, access connections between terminal and intersections based on investigations and reasonable calculation methods. The method proposed in the paper is simple and practical, which could be a reference for traffic safety improvement of the current off ramp-street terminal.
