为了优化交叉口的通行效率，开展了信号交叉口不同相位控制方式之间的临界流量研究。以周期流量、平均速度和行驶时间为参数，建立了两种控制方式下交叉口通行效率模型。结合两相位和四相位交叉口的具体特性，解析了各参数之间的函数关系，将交叉口通行效率模型简化为仅含流量的函数，从而求得了两种不同相位控制方式交叉口在不同流量条件下的通行效率具体数值，通过比较最终确定了适合两种相位控制的临界流量值。结果表明，该方法可以通过直行及左转车的小时流量来确定交叉口的控制方式，从而为交叉口通行效率的优化，以及控制与管理方法提供决策支持。

To optimize efficiency of signalized intersections, this paper studies critical volumes for different signal phase. Cycle volume, average velocity, and travel time were selected as three parameters, and the effi-ciency models of intersections were developed. Considering the characteristics of two-phase and four-phase signalized intersections, the functions between parameters were analyzed, thus the efficiency models were simplified to equations only including the parameter of volume. The values of efficiency and critical volume were obtained for two-phase and four-phase signalized intersections. The conclusion indicates that the meth-od can optimize the efficiency and provide theoretical basis for control and management of signalized inter-sections.
