Does Environmental Walkability Matter? The Role of Walkable Environment in Active Commuting

Area of Science:

• Urban Planning and Environmental Health
• Transportation Science
• Public Health

Background:

• Walkability is crucial for active commuting, prompting integration into urban planning.
• Cities worldwide are implementing policies to enhance walkability.
• Understanding the relationship between walkability and active commuting is vital for public health and sustainable urban development.

Purpose of the Study:

• To examine the association between walkability and active commuting in Seoul, Korea.
• To quantify the impact of Walkability Score on the probability of active commuting.
• To provide evidence-based policy recommendations for urban planning and transport engineering.

Main Methods:

• Utilized a multilevel logistic regression model with 129,044 individual samples across 424 administrative districts.
• Analyzed three models: individual variables only, individual variables plus Walkability Score, and individual/neighborhood variables plus Walkability Score.
• Controlled for individual demographic and socioeconomic factors, and included neighborhood-level variables like public transportation density.

Main Results:

• A significant positive correlation was found between Walkability Score and the odds of active commuting.
• Each one-point increase in Walkability Score was associated with a 0.3% increase in the odds of active commuting.
• Public transportation density, younger age, female gender, lower income, and lack of car ownership were also positively associated with active commuting.

Conclusions:

• Enhanced urban walkability is a key factor in promoting active commuting.
• Urban planning and transport policies should prioritize walkability improvements to encourage active travel.
• Findings support the integration of walkability assessments into environmental and transport planning to foster healthier and more sustainable cities.
