One of the primary concerns about data from GPS tracking apps is that the users tend to be more frequent recreators or commuters and therefore do not accurately represent the actual population. This paper shows that there is a strong correlation between the reported share of people in a neighborhood commuting by active transportation between the American Community Survey (a nationally representative survey) and Strava (a GPS tracking app).
The economic impacts and uses of long-distance trails
Although visitor spending per day along the Overmountain Victory National Historic Trail in western Virginia, Tennessee, North Carolina, and South Carolina is relatively low, the large number of visitors generates substantial economic impact. However, much of this spending is likely due to the attraction of specific historic sites and not the trail, because relatively few visitors were aware that the historic sites are connected to a larger regional trail.
A Community-Based Approach to Promoting Walking in Rural Areas
This study found that in southeastern Missouri, public health interventions to increase residents’ trail use, such as newsletters and fun walks, had no statistically-observable effect on residents’ walking habits or physical activity. A third of those who use the trail report increased overall physical activity levels since they began using the trail, suggesting while that trails can increase community physical activity, a primary challenge is getting residents to begin using them.
