| Abstract |
This study investigates the service range of commercial amenities?a concept defined by Christaller as the maximum distance people are
typically willing to travel to purchase goods?as an indicator of proximity. We measured the service range by calculating the
population-weighted 90th percentile of the nearest distance to 129 types of commercial amenities in Seoul, South Korea. The results reveal
substantial variation in service range across different types of amenities, enabling their classification into five hierarchical neighborhood levels.
Compared to existing urban planning guidelines, the result indicates that residents in Seoul tend to access a broader variety of amenities
within shorter distances. The findings also demonstrate that employing amenity-specific service range values provides a more realistic and
precise assessment of accessibility compared to traditional fixed-distance buffers, such as 400 or 800 meters, thereby more accurately
reflecting real-world proximity. This study contributes a methodological approach for assessing commercial amenity accessibility and offers
data-driven insights for future neighborhood-level commercial planning strategies. |
