摘　　要：为了减少右转机动车与直行自行车之间的干扰,提高交叉口的运行效率,本文分析了两相位信号控制交叉口右转机动车与自行车之间的冲突规律以及自行车交通流的行驶特性,确定设置右转机动车信号的直行自行车流量临界值.以减少冲突和提高交叉口运行效率为目标,确定右转机动车相位绿灯起亮时刻和绿灯时长,并建立了相应的参数标定模型.以实际调查数据为基础,应用VISSIM模拟软件进行模拟验证,结果表明,设置右转机动车信号后,右转机动车延误和机非冲突明显减少.In order to reduce the conflict between right - turn vehicles and through bicycles, o enhance the operational efficiency, we analyze the conflict mechanism between fight -turn vehicles and through bicycles and running characteristics of bicycles on two - phase intersection, and determine the critical value of through bicycle flow for setting fight - turn vehicle signal. For the sake of reducing the conflict and enhancing the intersectional operational efficiency, we determine the start - up of green time and its length, and then establish a relevant model of parameters demarcated. Based on collected data in field, the simulated verification is com- pleted by VISSIM. The results indicate that the delay of right - turn vehicles and the conflict are reduced obvi- ously. ： ＇
