为了改进评估交通基础设施投资收益的方法，本文试图开发一种方法来捕捉出行时间支出变化的变化，并展示了来自德国机动性小组数据的经验结果，这是一项多天、多时期的小组调查。所提出的方法可以同时和明确地处理变化和变化。实证分析表明，随着时间的推移，旅行时间支出更多地依赖于情景属性，而不是个人或家庭属性；这种依赖意味着旅行时间支出朝着多样化的方向变化，更长的行为观察期来描述人们的旅行时间支出变得更加重要。这些结果还表明，理解行为的动态方面仍然很重要，仍然是一个需要重新探讨的具有挑战性的问题，不仅是为了改进预测模型，也是为了重新考虑交通基础设施投资的好处。
To improve methods of evaluating the benefits from investments in the transport infrastructure, this paper attempts to develop a method for capturing changes in variations in travel time expenditure and shows empirical results from data from the German Mobility Panel, a multiday and multiperiod panel survey. The proposed methodology can simultaneously and explicitly deal with changes and variations. The empirical analysis indicates that over time, travel time expenditures become more dependent on situational attributes than on individual or household attributes; such dependence implies that travel time expenditures change toward diversification and that longer periods of behavioral observation to describe people's travel time expenditures become more important. The results also imply that understanding of the dynamic aspects of behavior is still important and remains a challenging issue to be revisited, not only for improving forecasting models but also for reconsidering the benefits from investment in transportation infrastructure.
