摘　　要：在城市交叉口所有方向车流中,左转车流是对交叉口影响最大的车流。它不但会增加交叉口的平均延误,而且会大大增加交叉口的冲突点个数,对交叉口的安全性有重要的影响。从交通工程设计和安全角度出发,在广泛参照国内外先进设计理论和方法的基础上,提出一种新型的立体下沉式无障碍交叉口左转交通设计。The left-turn traffic flow has the most influence to intersections among all directions traffic flows in urban intersections, which not only increases average delay of intersections, but also increase the numbers of conflict points, having significant impact on intersection safety. In view of traffic engineering design and safety, based on referring the advanced design theory and methods both at home and abroad, this paper presents the barrier-free left-turn traffic design for new type sunken intersections.
