平交路口远引掉头技术应用研究的思考

本文旨在提出符合我国变通特性的平交路口远引掉头技术应用研究思路。首先，作者对国内外研究现状进行了简要的回顾和总结，从中发现国内研究存在的主要问题；然后，从我国道路交通环境出发，有针对性地提出了基于微观仿真的技术研究思路。主要从中央分隔带开口布局、中央分隔带设计和机非分离的交通组织方案等方面，对远引掉头技术研究思路做了系统的规划。

Considering of the Application Research of Indirect Left Turn with U-turn at Intersection

The purpose of this paper is to introduce the technical methods of U-turn at intersections, which is accorded with the traffic characteristics of China. Brief review of current research situation in home and abroad is done firstly. Problems are found from the domestic research status. Then, technical methods based on microscopic simulation are introduced according to the traffic circumstance of China. Considering of the research is put forward for the technology of U-turn on the respects of the median opening layout, median design, the traffic organization of separating motor and non-motor, etc.
