Neighbourhood walkability is a measure of how well a neighbourhood promotes active forms of transportation, such as walking. A highly walkable neighbourhood has a variety of destinations within walking distance, well-connected streets and a mix of land uses. Walkability can increase physical activity levels across a broad population and reduce the risk of many chronic diseases.
We have completed several projects that examined neighbourhood walkability and its relationships with physical activity. In each of these projects, we used the Walk Score® metric (data provided by Redfin Real Estate) to assess walkability. Additional projects are planned that will investigate walkability and chronic disease risk.
OEH Seminar: Building an evidence base for better subway air quality: The Subway Air Quality Initiative
Over the past 20 years, the body of research on subway air quality has grown dramatically. This work revealed high particulate matter (PM) levels sourced from brake and steel dust.
