1. A computer implemented method for assessing road quality using data collected form a mobile device, the method comprising: obtaining, by one or more processors, travel data collected by the mobile device during a mobile device traversal, the travel data including acceleration data associated with the mobile device during the mobile device traversal; analyzing, by the one or more processors, the travel data according to one or more heuristics, each heuristic providing a heuristic metric indicative of whether the mobile device traversal is a human-carried mobile device traversal; determining, by the one or more processors, a confidence score for the travel data based on the heuristic metric provided by each of the one or more heuristics; processing, by the one or more processors, the travel data to assess road quality for a section of a road based at least in part on the confidence score, including discarding the travel data when the confidence score does not exceed a confidence threshold; and providing, by the one or more processors, an indication of road quality for the section of the road to a user approaching the road segment.
