Mapping Slow Mobility Users' Unhealthy Exposure to Air Pollution in London

Area of Science:

• Environmental Science
• Urban Planning
• Public Health

Background:

• Slow mobility (walking, cycling) offers health and environmental benefits but increases exposure to urban air pollution.
• Understanding this exposure is crucial for developing healthier urban environments.

Purpose of the Study:

• To quantify and spatially analyze air pollution exposure for slow mobility users in London.
• To inform sustainable urban planning and promote healthier city living.

Main Methods:

• A data-driven framework was developed to assess air pollution exposure related to slow mobility.
• London's air quality data (PM2.5, PM10, NOx) was overlaid with accessibility mapping (15-min city concept) and OpenStreetMap data.

Main Results:

• Central London shows high accessibility coupled with high air pollution exposure.
• Nitrogen oxides (NOx) exposure is consistently higher than PM10 and PM2.5 for slow mobility users.
• Air quality in London is projected to improve significantly by 2030.

Conclusions:

• Empirical evidence supports people-centered urban development and stakeholder collaboration.
• Achieving strategic urban goals for London by 2030 requires joint efforts.
