The relationship between walk score® and perceived walkability in ultrahigh density areas

Area of Science:

• Urban Planning
• Environmental Health
• Geographic Information Systems

Background:

• Walk Score® is a web-based tool assessing location walkability.
• Previous studies linked Walk Score® to built environment attributes in North America.
• Its applicability in Asian ultrahigh-density urban settings remained unexplored.

Purpose of the Study:

• To investigate the correlation between Walk Score® and perceived built environment attributes in Japan.
• To examine covariate-adjusted associations in ultrahigh-density Japanese urban areas.
• To assess the validity of Walk Score® in an Asian context.

Main Methods:

• Cross-sectional study design.
• Randomly selected adult residents from two Japanese urban localities.
• Analysis of correlations between Walk Score® and perceived environmental measures.

Main Results:

• Strong correlation between Walk Score® and access to shops (0.58).
• Medium correlations observed with population density, public transport access, sidewalks, and recreational facilities.
• Small correlations found with bike lanes and a small negative correlation with traffic safety.
• Medium correlation with overall perceived walkability (0.48).

Conclusions:

• Walk Score® demonstrates significant correlations with various perceived walkable environment attributes in ultrahigh-density Asian urban areas.
• Findings support the utility of Walk Score® as a measure of walkability in diverse global contexts.
• The study validates Walk Score®'s relevance beyond North American settings.
