Association Between User-Generated Commuting Data and Population-Representative Active Commuting Surveillance Data—Four Cities, 2014-2015
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).
