【摘要】：针对导流岛冲突区非机动车与行人具有优先通行权的假设与实际运行状况不符的情况,描述了机动车截流效应,并以冲突技术法为基础,提出了针对导流岛信号交叉口的右转车道实际通行能力模型.该模型充分考虑了信号控制、非机动车与行人的混合流率、非机动车与行人过街群的过街时间、非机动车与行人过街群的单群个数及人行横道宽度等因素的影响,并采用福州市的实测数据对模型进行标定与检验.结果表明:提出的模型能较好地反映导流岛冲突区的实际运行状况.
[Abstract]:In view of the fact that the assumption that non-motor vehicles and pedestrians have priority right of passage in conflict zone of diversion island is not in accordance with the actual running condition, the effect of motor vehicle closure is described, and the conflict technique method is used as the basis. The actual capacity model of the right turning lane for the signal intersection of the diversion island is proposed. The effects of signal control, mixed flow rate of non-motor vehicle and pedestrian, crossing time of non-motor vehicle and pedestrian group, single group number of non-motor vehicle and pedestrian crossing group and width of crosswalk are fully considered in the model. The model is calibrated and verified by the measured data of Fuzhou. The results show that the proposed model can better reflect the actual operation of the conflict zone of the diversion island.
