摘要
运用间隙接受理论分析了匝道车辆在高速公路合流区汇入主路的运行状态。基于主路车流车头时距服从移位负指数分布,建立了高速公路入口匝道合流区的通行能力模型。模型表明它是主路交通量、匝道交通量、匝道车辆临界间隙、随车时距及加速车道长度的函数。
The merging behavior of on-ramp vehicle is analyzed with gap acceptance theory. Based on the hypothesis that the headway distribution of traffic is shifted-negative- exponential distribution, the highway capacity model of freeway on-ramp junction is found by analyzing the gap acceptance process, and the model is a function of flow rate, critical gap, following time and the length of acceleration lane.
