Association between Composition of Main Transportation Modes and Average Walking Time in Japanese Cities

A Descriptive Epidemiological Study Using Nationwide Data

Abstract

Despite regional differences in residents' physical activity, large-scale data that account for urban characteristics are limited. This study described the association between the composition of main transportation modes used in each city and residents' average walking time. An online survey was conducted in December 2021 among residents of 70 cities where the 2015 National Person Trip Survey was conducted, and 28,449 people were included in the analysis (50.5% male, 49.6±15.6 years old). The percentage of rail use correlated most strongly positively with average total walking time, while that of car use (self-driving) correlated strongly negatively with average walking time for walking, commuting, and shopping.
