动态路段行程时间函数与BPR函数的比较研究

从交通流参数的处理入手 ,研究和分析了动态路段行程时间函数的确定过程 ,提出了动态路段行程时间函数式 ,并且与计算路段行程时间常用的BPR函数进行了比较 ,指出动态路段行程时间函数不但考虑了路段机动车交通量的动态性 ,更注重了路段出口交通量的变化情况 ,符合实际交通状况 ,具有实时、简单、实用等特点 ,适于在交通管理中运用

Function of journey time on dynamic highway section compare with BPR function

Proceed with treatment of the trafic flow parameter and study and analyse dynamic highway section journey time the definite courses of functions, propose dynamic highway section journey time function types is amidst flowers and in the moonlight with calculating highway section compare by commonly used BPR function of journey time, dynamic highway section consider highway section motor vehicle the dynamic qualitieses of volume of traffic by journey time function, pay attention to highway section export the situations of change of volume of traffic and correspond to reality kind traffic, have real time, simpleness, practical and so on suitable for using during traffic administration.
