2014年初，英国交通部（DfT）委托进行了自20世纪90年代中期以来的第一次全国旅行时间价值（VTT）研究。本文件介绍了为这项研究开展的方法学工作，在调查设计和建模方法两个方面都有沿着若干方面的重要创新。我们的研究结果显示了丰富的模式的异质性，在整个旅游公众，在VTT的影响方面的人和行程的特点，以及一个主要的角色，涉及到的具体选择所面临的一个假设的选择设置，包括参考依赖性和非线性的敏感性。我们还讨论了如何将这些行为价值转化为用于评估的价值，以及在使用先进模型获得的结果的基础上进行评估时所面临的挑战。(C)2016爱思唯尔有限公司版权所有
In early 2014, the UK Department for Transport (DfT) commissioned the first national value of travel time (VTT) study since the mid-1990s. This paper presents the methodological work undertaken for this study, with important innovations along a number of dimensions, both in terms of survey design and modelling methodology. Our findings show a rich pattern of heterogeneity across the travelling public, in terms of an impact on the VTT by both person and trip characteristics, as well as a major role for a number of characteristics that relate to the specific choices faced in a hypothetical stated choice setting, including reference dependence and non-linearities in sensitivities. We also discuss how these behavioural values were translated into values for use in appraisal, and the challenges faced when doing this on the basis of results obtained with advanced models.
