摘　　要：城市地面道路的交叉路口,是最容易发生交通拥堵的地方。该文探讨一种新型两相位(掉头)信号控制模式,既保持了两相位的高效率,又有效地组织了左转弯车流,充分发挥路网系统的整体优势,大力提升平面交叉路口的通行效率,有利于缓解大城市交通拥堵状况。The intersection of urban ground road is the place where the traffic jam is the most easy to happen. The article discusses a new two-phase (turn-aroud) single control mode,which not only keeps the high efficiency of two phases,but also organizes the turn-left vehicle flow. It fully play the integral superiority of the road network system,greatly upgrades the traffic efficiency of the plain intersection,and is propitious to relax the traffic jam status in the large cities.
