摘　　要：机非混合交通是我国城市交通流的重要特征,相同相位不同行驶方向的机动车交通流与自行车交通流在平面信号交叉口区域内存在大量的干扰和冲突。文中介绍了交叉口右转机动车流与自行车流之间的冲突类型及相互干扰特性,并以实际观测的交通数据为依据,借鉴并引用了自行车组这一概念,根据临界间隙理论,建立了信号交叉口在直行自行车流影响下的右转机动车饱和流率模型,并对模型进行了验证与修正,使之更符合实际情况。Mixed traffic flow is one of the important traffic characteristics in large cities of China. There are great interference and conflicts between the bicycles and motorized vehicles in the same phase but heading for different directions.This paper introduced the types of conflicts and the mechanism of interference between right-turning vehicles and through bicycles in signalized intersection. The data of crossing behavior of through bicycles and right-turning vehicles in the same direction at typical signalized intersection in Nanjing were collected and analyzed. New concept of bicycle group was introduced in this study. Based on the critical gap theory, it was established the saturation flow rate model of right-turn vehicles under the influence of the bicycle in the signalized intersection. The model was validated and amended in order to be more in line with the situations.
