Metro is based on all non-private activities. We have developed a model to detect and identify commutes, which uses the commute tag used by Strava members as a ground truth. In our model, “commuting” refers to all non-leisure trips.
As a result, it is not necessary for a Strava member to mark their activity as a commute in the app in order for it to be included in commuting analyses on the Metro platform. However, it is of course very helpful that many Strava members do mark their activities as commutes, and we hope to make the commuting experience on Strava more rewarding and exciting in the future.
