| 摘 要： | 城市配送出行里程估计对城市货运交通的规划和管理有重要意义。目前已有多位学者对这些因素综合考虑建立了一些定量计算的模型,并且有学者研究指出了配送车辆运行的时间分布对出行里程的重要影响,但目前没有出现将时间因素考虑在内的估计模型。通过引入一个时间和空间分区的二维订单密度,对标准出行里程模型进行重新推导,构建包含时间因素的城市配送出行里程估计模型,使模型更接近现实情况。

| Abstract: | The vehicle kilometers traveled(VKT) is an important factor to be considered in urban freight transport or logistics planning.At present,some quantitative models have been constructed to estimate the VKT.Some study also indicates that the time window of vehicle working hours have great effects on the length of urban distribution trips.But there is no VKT estimate models including the window time factor until now.As a result,we introduced a two dimensional orders density: time dimension and space dimension. ... |
