时间价值（VOT）的量化对于衡量交通项目在旅行时间节省方面的效益非常重要。在日本，人们认为周末的VOT比工作日高，因为在周末，人们有有限的时间分配给工作日通常不做的自由活动，如家庭护理相关活动。在印度尼西亚，一个多元文化的国家，供应商和用户似乎有不同的看法的VOT。提出了一种分析活动时间价值的方法。本文认为，应该通过考虑自由支配活动的价值来更详细地评估周末节省旅行时间的好处，以便从理论上解释这些现象。在日本东京和印度尼西亚雅加达进行了活动日记调查，以验证心理需求对人们假期活动的影响。最后，一个时间分配模型，使用显示的偏好数据和边际活动选择模型，使用陈述的偏好数据，提出了计算活动时间的价值。这些模型的理论基础是马斯洛的心理需求，经济学中的消费者理论和离散选择模型。实证结果表明，个体的需求优先级影响时间分配。特别是，结果显示，在东京，周末与家人共度的时间比其他类型的活动更有价值，而在印度尼西亚，与家人共度的时间的价值甚至超过了工作时间。
Quantification of the value of time (VOT) is important for measurement of the benefit of transportation projects in terms of travel time savings. In Japan, VOT is considered higher on weekends than on weekdays because on the weekend people have limited time to allocate to discretionary activities that are not normally done on weekdays, such as family care-related activities. In Indonesia, a culturally diverse country, providers and users seem to have different perceptions of VOT. A method of analyzing the value of activity time is presented. It argues that the benefit of travel time saving should be evaluated in more detail on weekends by considering the value of discretionary activities to explain these phenomena theoretically. Activity diary surveys were conducted in Tokyo, Japan, and Jakarta, Indonesia, to verify the influence of psychological needs on people's holiday activities. Finally, a time allocation model that uses the revealed preference data and a marginal activity choice model that uses stated preference data are proposed to calculate the value of activity time. The theories underpinning these models are Maslow's psychological needs, consumer theory in economics, and a discrete choice model. The empirical results show that an individual's priority of needs influences time allocation. In particular, the results show that in Tokyo, spending time with family on weekends is more valuable than other types of activities, while in Indonesia the value of spending time with family exceeds that of work time even on weekdays.
