在本文中，我们报告了将一个新的微观经济框架应用于活动、商品消费和模式选择的时间分配模型的结果(Jara-Diaz and Guevara, 2003；Jara-Diaz和Guerra， 2003)，它确定了这些决策之间的联系，并允许计算文献中定义的时间主观价值的所有组成部分：时间作为资源的价值，为特定活动分配时间的价值，以及在特定受限活动中节省时间的价值。用于建模的样本分别来自德国和瑞士的六周旅行日记Mobidrive （Axhausen et al., 2002）和Thurgau （Axhausen et al., 2005; Lochl et al., 2005）。在本文中，我们提出了模型系统，包括分配给活动和模式选择的时间，对数据集的描述，对建模所需变量的生成工作的总结，校准模型的结果，除了德国样本的节省和分配旅行时间的值之外，还包括两个样本的休闲和工作值，以及它们的分析和解释。如果我们考虑到获得的主观时间值与预期一致，休闲时间的正值和分配旅行时间的负值，那么结果是合适的。
In this paper we report the results of applying a new microeconomic framework to model time assignment to activities, goods consumption and mode choice jointly (Jara-Diaz and Guevara, 2003; Jara-Diaz and Guerra, 2003) that identifies the links between these decisions and permits the calculation of all the components of the subjective value of time defined in the literature: the value of time as a resource, value of assigning time to a specific activity and the value of saving time in a specific constrained activity. The samples used for the modelling come from the six-weeks travel diaries Mobidrive (Axhausen et al., 2002) and Thurgau (Axhausen et al., 2005; Lochl et al., 2005) collected in Germany and Switzerland, respectively. In this paper we present the model system that includes time assigned to activities and mode choice, a description of the data sets, a summary of the generation work of necessary variables for the modeling, the results of the calibrated models, which include the values of leisure and work for both samples, besides the values of saving and assigning travel time for the German sample, and their analysis and interpretation. The results are appropriate if we consider that the subjective values of time obtained are coherent with what was expected, positive values of leisure and negatives values of assigning travel time.
