Description

In recent years, increased redeliveries of home delivery parcels have become a societal problem. One reason for this problem is the increased number of households with every member out-of-home (HEMOs). However, few research has shown empirically the temporal rate of HEMOs. In this study, we calculated the HEMO rate as well as the individual-based out-of-home rate using Person Trip (PT) survey data. Specifically, we compare these rates with two time-series datasets from a Kumamoto PT survey and discuss the factors for change. As a result, the HEMO rate rose considerably, though there was no major individual-based rate change over 15 years. We also decomposed the factors of changes in household composition ratios and changes in the HEMO rate for household type.
