Public transportation require access trips to the stops, which are significantly affected by external environmental factors. This study examined the changes in public transportation usage based on these characteristics in relation to external environments. The analysis focuses on the 25 administrative districts of Seoul, using data on public transportation usage, weather, and air quality from 2023. The analysis used a Panel-SUR model, showing that deteriorating weather and air quality reduce public transportation usage. The impact of the variables was greater on weekends than on weekdays, likely because non-essential trips, which mainly occur on weekends, can be influenced by external environmental conditions when choosing whether to travel. The air quality-related variables have a smaller impact on subways than buses, likely because bus stops are more exposed to external environments.
