摘　　要：为了提升交叉口服务水平,在常规四相位信号控制的基础上重新调整信号相序,设计一种新型行人二次过街模式,通过VISSIM软件建立对比模型,采集车辆平均通过时间(VATT)、车辆平均延误时间(VAD)、行人平均通过时间(PATT)、行人平均延误时间(PAD)、每小时通过交叉口的车辆(NV)和每小时通过交叉口的行人数(NP)等数据评估过街模型的运行效率。结果表明,各模型在VATT、VAD、NV及NP等方面差距不明显;而采用新型二次过街模式的交叉口在PATT和PAD方面运行效率有显著提升。In order to improve intersection service level,this paper on the basis of conventional four phase signal control,this article readjusts the signal phase sequence and designs a new pedestrian twice crossing mode.Comparative models are established using VISSIM to collect data such as vehicle average travel time(VATT),vehicle average delay(VAD),pedestrian average travel time(PATT),pedestrian average delay(PAD),and the number of vehicles(NV)and the number of pedestrians(NP)passing through the intersection per hour to evaluate the operational efficiency of each crossing model.The results show that there is no significant difference between the models in terms of VATT,VAD,NV,and NP.The intersection using the new secondary crossing mode has significantly improved operational efficiency in terms of PATT and PAD.
