【摘要】：針對(duì)導(dǎo)流島沖突區(qū)非機(jī)動(dòng)車(chē)與行人具有優(yōu)先通行權(quán)的假設(shè)與實(shí)際運(yùn)行狀況不符的情況,描述了機(jī)動(dòng)車(chē)截流效應(yīng),并以沖突技術(shù)法為基礎(chǔ),提出了針對(duì)導(dǎo)流島信號(hào)交叉口的右轉(zhuǎn)車(chē)道實(shí)際通行能力模型.該模型充分考慮了信號(hào)控制、非機(jī)動(dòng)車(chē)與行人的混合流率、非機(jī)動(dòng)車(chē)與行人過(guò)街群的過(guò)街時(shí)間、非機(jī)動(dòng)車(chē)與行人過(guò)街群的單群個(gè)數(shù)及人行橫道寬度等因素的影響,并采用福州市的實(shí)測(cè)數(shù)據(jù)對(duì)模型進(jìn)行標(biāo)定與檢驗(yàn).結(jié)果表明:提出的模型能較好地反映導(dǎo)流島沖突區(qū)的實(shí)際運(yùn)行狀況.
[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.
