1. A computer implemented method for assessing road quality using data collected from a mobile device, the method comprising: obtaining travel data associated with a mobile device traversal, the travel data including acceleration data associated with the mobile device during the mobile device traversal; analyzing 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 a confidence score for the travel data based on the heuristic metric provided by each of the one or more heuristics; and processing the travel data based at least in part on the confidence score, the processed travel data configured to be used to assess road quality.
