Stated choice surveys have established themselves as the preferred approach for value of travel time elicitation with the help of choice models. However, major differences exist in the approach used across regions and contexts. In Europe (particularly Northern Europe), value of travel time is often estimated in large national studies, which continue to rely extensively on simple time-money trade-offs. On the other hand, studies in Australia and South America in particular tend to have a more local focus and follow the notion that more complex setups are preferable. The European studies however are also those where the results are actually used in cost–benefit analysis and data from European studies have formed a testbed for many advanced model specifications. The present paper aims to provide a critical appraisal of the use of simple time-money trade-offs, drawing from our experience in recent European studies. We highlight a number of issues, in terms of differences in valuations across formats as well as a lack of clarity on how respondents actually interpret travel time in these simple time-money trade-offs.

使用简单的时间-金钱权衡对旅行时间度量的评估价值进行批判性评估

在选择模型的帮助下，明确的选择调查已成为获取旅行时间价值的首选方法。然而，在不同地区和不同背景下使用的方法存在重大差异。在欧洲（尤其是北欧），旅行时间的价值通常在大型国家研究中进行估计，这些研究继续广泛依赖于简单的时间-金钱权衡。另一方面，特别是在澳大利亚和南美洲的研究往往更关注本地，并遵循更复杂的设置更可取的观点。然而，欧洲研究也是将结果实际用于成本效益分析的研究，并且来自欧洲研究的数据已经形成了许多先进模型规格的试验台。本文旨在根据我们在最近的欧洲研究中的经验，对简单的时间金钱权衡的使用进行批判性评估。我们强调了一些问题，包括不同格式的估值差异以及受访者如何在这些简单的时间金钱权衡中实际解释旅行时间的问题。
