The Physical Environment and Active Transportation (PEAT) Study will evaluate how the new Silver Line Metrorail of the Washington, DC rapid transit system contributes to adolescent active transportation habits and how these transportation habits can potentially affect adolescents’ physical activity levels and overweight/obesity rates.

Active Transportation

Active transportation, such as walking, biking or using public transportation, as a means of transportation, has increasingly been viewed as a strategic and integral pathway to increasing physical activity levels in youth and thus reducing overweight or obesity levels.  Adolescents that use active transportation have better cardiorespiratory and muscular fitness, increased energy expenditure, more favorable body composition and less weight gain.  Despite these benefits, it is not well understood how environmental and social factors are associated with the adoption of active transportation behavior.

Built and Social Environment

Neighborhood street connectivity, land use, urbanicity, family time constraints, adolescent fear coping, and parental risk perceptions, can influence active transportation patterns. However, the dynamic relationship of these environmental and social factors has not been examined extensively.  Most of the youth active transportation research has emphasized walking and cycling.  A few studies have examined public transportation and adolescent active transportation and nearly all of those studies have occurred outside of the U.S.  The Physical Environment and Active Transportation (PEAT) Study will evaluate how a newly introduced public transportation system extension and the social environment contribute to adolescent active transportation habits and how these transportation habits can potentially affect adolescents’ physical activity levels and obesity rates. 

The PEAT Study

The PEAT Study will explore the impact of a Washington, DC Metropolitan Area Transit Authority (Metro) extension (The Dulles Corridor Metrorail Project (Silver Line)) on adolescent active transportation in Fairfax County, Virginia, where more than one quarter of youth are overweight or obese. The Silver Line recently opened on July 26, 2014 with a total of 28 stations, including five new stations in Fairfax County, Virginia. This Metro system extension now provides a new physical environment and an opportunity for adolescents to engage in active transportation to and from Metro stations on their way to school and other destinations.
