了解人口的时空分布特征是城市减灾规划领域中最重要的问题之一。人口的时空分布随一天的时间和一周的某一天(工作日或周末)而变化。然而，现有的基于平日的人员出行调查数据不适合估计周末人口的时空分布。在本研究中，我们提出了一种将现有的人员旅行调查数据从平日基础转换为周末基础的方法，并检验了人口时空分布的差异。使用这些数据库，我们试图比较东京大都市区不同地区平日和周末因建筑物倒塌而死亡的估计人数。
Understanding the characteristics of the spatiotemporal distribution of a population, which varies according to the time of the day and the day of the week (weekday or weekend), is one of the most important issues in the field of urban disaster mitigation planning. However, the existing Person Trip Survey data based on weekdays is not appropriate for estimating the spatiotemporal distribution of population on weekends. In the present study, we proposed a method for converting existing Person Trip Survey data from a weekday base to a weekend base and examined the differences in the spatiotemporal distribution of the population. Using these databases, we attempted to compare the number of deaths due to building collapse estimated for weekdays and weekends for various districts in the Tokyo Metropolitan area.
