本文考察了货物运输的效率。首先建立了理论最优解，然后分析了实际交通系统偏离这一理想的方式。一个一般的框架效率模型，其次是一个具体的效率模型，区域公路为基础的分配/收集环节的货物在长距离移动。然后，本文介绍了专家对目前的低效率水平，其可变性和潜在的改进意见。研究结果表明，货物运输的整体物理效率模型的理论出发点，可以找到一个完整的部分效率的基础上。实证结果已经确定了几个方面的区域小于卡车装载分配/收集具有低的平均效率和/或高的变异系数，结合良好的改善潜力，特别是营业时间，驾驶时间，回程因素，实际行程执行，占地面积利用率，和实际装载执行。
This paper examines the efficiency of freight transportation. It first establishes the theoretical optimum and then analyzes the ways in which actual transportation system deviates from this ideal. A general framework efficiency model is presented, followed by a specific efficiency model for regional road-based distribution/collection link for goods moved over long distances. The paper then presents expert opinion on the current level of inefficiency, its variability, and potential improvement. The results of the study show that a theoretical starting point for an overall physical efficiency model of freight transportation can be found based on a full range of partial efficiencies. The empirical results have identified several aspects of regional less than truckload distribution/collection as having a low average efficiency and/or a high coefficient of variation, combined with a good potential for improvement; in particular business time, driving time, back haul factor, actual trip execution, floor space utilization, and actual loading execution.
