Environmental and Policy Approaches to Increase Physical Activity: Street-Scale Urban Design Land Use Policies
Street-scale urban design and land use policies involve the efforts of urban planners, architects, engineers, developers, and public health professionals to change the physical environment of small geographic areas, generally limited to a few blocks, in ways that support physical activity.
- Policy instruments employed include:
- Building codes
- Roadway design standards
- Environmental changes
- Design components include:
- Improved street lighting
- Infrastructure projects to increase safety of street crossing
- Use of traffic calming approaches (e.g., speed humps, traffic circles)
- Enhancing street landscaping
Summary of Task Force Recommendations and Findings
The Community Preventive Services Task Force recommends urban design and land use policies and practices that support physical activity in small geographic areas (generally a few blocks) based on sufficient evidence of their effectiveness in increasing physical activity.
Results from the Systematic Reviews
Six studies qualified for review and evaluated a variety of effect measures.
- Reviewed studies assessed the relationship between the perceived environment and physical activity practices, or effectiveness in providing a more inviting and safer outdoor environment for activity.
- Overall, the median improvement in some aspect of physical activity (e.g., number of walkers or percent of active individuals) was 35%.
- Additional benefits that may have been brought about by these interventions included:
- Improvements in green space
- Increased sense of community and decreased isolation
- Reductions in crime and stress
- Increased walking and bicycling on urban streets, although beneficial, also pose the risk of increased injury to pedestrian or cyclist, because of increased exposure to motor vehicles.
These results were based on a systematic review of all available studies, conducted on behalf of the Task Force by a team of specialists in systematic review methods, and in research, practice, and policy related to increasing physical activity.
