Research on Model of Computing Acceleration Lane Length and Analysis of Its Influence Factors

摘要: 在分析合流过程中匝道车辆运行特点以及合流影响因素的基础上,提出用相对车头时距的概念刻画主线车流与合流车辆运行速度以及主线流量对合流的影响,得到了新的加速车道长度计算模型。并对模型及其影响因素进行了分析.

Abstract: Based on the process of merging on expressways and characteristics of running vehicles involved in the merging,this paper defines relative time headway to describe the velocity of vehicles involved in merging process and the volume of the main lane.A new model for computing acceleration lane is put forward and the influence factors are analyzed.
