摘　　要：机动车待行区的设置对交叉口空间资源的有效利用、交叉口通行能力的提高和延误的减少具有重要作用.在讨论机动车待行区设置条件的基础上,首先介绍了左转待转区和直行待行区的设置形式,并对每一种方式从渠化设计和信号控制设计两个方面分别介绍了交通组织方法,并讨论了设置机动车待行区对通行能力的影响.然后以官园桥下平面交叉口为案例展开实证研究,并以VISSIM对改善效果进行了仿真.仿真结果表明,设置待行区域后,交叉口通行能力提升了17.4%,而交叉口的平均延误降低了26.1%.To increase the capacity of a road intersection and the traffic capacity,and reduce the traffic delays at the intersection,the settlement of the waiting-areas for auto-vehicles is very important.The methods of organizing traffic flows in a signalized intersection with waiting-areas,channelized design and signal control are analyzed in this research.The effect of the establishment of the waiting-areas for auto-vehicles turning left or going straight on the traffic capacity has been discussed in consideration of channelized design and signal control.Finally,with the utilization of the VISSM software,the increase of the intersection capacity and the decrease of the average delay at the entrance of a intersection have been studied by the simulation of the traffic condition at the Guanyuanqiao intersection.It turns out that the establishment of the waiting-areas for auto-vehicles is able to improve the traffic capacity at this intersection by 17.4% and decrease the average traffic delay by 26.1%.
