There is growing interest in increasing physical activity through promoting use of existing (or construction of new) community paths and trails. This study and corresponding collaborative effort aim to develop a core set of reliable trail use measures. Three different studies on trail use collaborated to develop closely related trail use measures that served different research purposes but remained comparable:

USC ROUTES Study (Reynolds, PI)
Studies trail use of users and non-users living within a one-mile buffer of 3 trails in LA, Dallas and Chicago - telephone recruitment.

IUPUI (Lindsey, PI)
Studies trail activity patterns and perceptions of trail users near 5 trails in the Indianapolis area, some data on non-users, telephone recruitment.

Harvard University (Troped, PI)
Studies users of six community trails and paths in Massachusetts by conducting brief trail intercept surveys & measuring on and off-trail activity with portable GPS units & accelerometers.
