摘要:

为探寻公路货运车辆实载率差异分析的科学方法,以获取提高公路货运车辆 实载率的有效途径,本文分析了方差分析、因素分析和假设检验等方法的应用局限性,结 合目前公路货运统计数据,提出了一种基于Kruskal-Wallis 检验的公路货运车辆实载率 差异分析的新方法,并以陕西省为例进行了验证.结果表明:不同区域、不同吨位、不同轴 数、不同经营模式的公路货运车辆实载率差异显著,多重比较的齐性子集区分明显.

Abstract:

To find a better variance analysis method for loading rates of road freight vehicles and obtain an effective way to improve loading rates, this paper analyses the application limitations on variance analysis, factor analysis and hypothesis testing. Then, using the current road transportation statistics data, the paper proposes a new method of variance analysis for loading rates of road freight vehicles based on Kruskal- Wallis test and validates the method in Shanxi Province, China. The results show that there are significant differences in road freight vehicle loading rates by different regions, tonnage, number of axes, and business models. And there is also a big difference among homogeneous subsets of multiple comparison tests.

Key words: highway transportation, variance analysis, Kruskal-Wallis test, freight vehicles, loading rates
