System and method for assessing road quality using data collected from a mobile device
First Claim
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.

Abstract
A computer implemented method for assessing road quality using data collected from a mobile device is disclosed. The method may include obtaining travel data associated with a mobile device traversal. The travel data may include acceleration data associated with the mobile device during the mobile device traversal. The method may also include analyzing the travel data according to one or more heuristics. Each heuristic may provide a heuristic metric indicative of whether the mobile device traversal is a human-carried mobile device traversal. In addition, the method may include 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, wherein the processed travel data is configured to be used to assess road quality.

15. A system for assessing road quality using data collected form a mobile device, the system comprising:
-
a computing device including a processor and memory, the memory storing instructions that, when executed by the processor, configure the computing device to; obtain 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; analyze 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; determine a confidence score for the travel data based on the heuristic metric provided by each of the one or more heuristics; process the travel data to assess road quality based at least in part on the confidence score, including discard the travel data when the confidence score does not exceed a confidence threshold; and using the assessed road quality, generate a driving route with a least amount of road surface anomalies to a user-selected travel destination. - View Dependent Claims (16, 17, 18, 19, 20)
