The COVID-19 pandemic accelerated active transportation (AT) policies and urban infrastructure changes, like bike lanes. This demonstrates how urgent health crises can drive policy for physical activity (PA).
Area of Science:
- Public Health
- Urban Planning
- Policy Science
Background:
- Physical activity (PA) policy is crucial for population health, requiring cross-sector collaboration.
- Global health crises, such as the COVID-19 pandemic, can create opportune moments for policy innovation and implementation.
- Active transportation (AT) policies are vital for promoting PA and adapting urban environments.
Purpose of the Study:
- To examine how policy windows during the COVID-19 pandemic influenced the development and implementation of active transportation (AT) policies.
- To assess the resulting infrastructural changes and their impact on population-level physical activity.
- To identify enablers and challenges associated with AT policy implementation during a public health emergency.
Main Methods:
- A systematic review of scientific literature published between 2020 and 2023 was conducted.
- Databases searched included PubMed, Scopus, WHO COVID-19 Research Database, and others.
- Descriptive analyses were performed using Stata, with PROSPERO registration CRD42025644930.
Main Results:
- The review identified 14 studies detailing AT policy changes during the pandemic.
- Significant infrastructural modifications, including new bicycle lanes and pedestrian zones, were observed.
- Policies often facilitated utilitarian PA and offered mobility alternatives during the pandemic, though many were temporary.
Conclusions:
- The pandemic demonstrated that urgency and political will can rapidly advance AT policies and urban infrastructure.
- Swift implementation of AT policies during health emergencies can effectively promote utilitarian physical activity.
- Understanding local contexts is key for the sustainable integration of AT initiatives in urban planning.
