1. A method for determining the location of a road distress, comprising:
- measuring, by a mobile sensor, a distress data for a road section, wherein the distress data comprises a distress time component and a distress action component;
identifying a relevant traffic data for the road section, the relevant traffic data comprising a traffic time component that corresponds to the distress time component;
calculating a probability of a road distress on the road section based on the distress data and relevant traffic data; and
responsive to the calculated probability exceeding a predetermined threshold probability, generating an alert identifying the road section;
wherein;
the road distress comprises at least one of a hole, a swell, a rock, and debris;
the distress data pertains to a first lane in the road section, and the traffic data pertains to a second lane in the road section, the first lane being adjacent to the second lane;
the distress data comprises a rapid deviation in an x-y plane followed by a rapid return to an initial trajectory for a vehicle in the first lane; and
the traffic data comprises a lack of any vehicles in the second lane at the traffic time component that corresponds to the distress time component.

Abstract
In various embodiments, the invention involves methods and systems suitable for roadway monitoring, mapping, and maintenance. The probability of a road distress is calculated by combining various sources of data, and automatic alerts are generated to request mobilization of a road repair resource. Various methods are included to increase the accuracy of the probability calculations.

11. A computer system for determining the location of a road distress, comprising:
-
a processor; a memory coupled to the processor, the memory configured to store program instructions executable by the processor to cause the computer system to; receive, from a mobile sensor, a distress data for a road section, wherein the distress data comprises a distress time component and a distress action component; identify a relevant traffic data for the road section, the relevant traffic data comprising a traffic time component that corresponds to the distress time component; calculate a probability of a road distress on the road section based on the distress data and relevant traffic data; and responsive to the calculated probability exceeding a predetermined threshold probability, generate an alert identifying the road section; wherein; the road distress comprises at least one of a hole, a swell, a rock, and debris; the distress data pertains to a first lane in the road section, and the traffic data pertains to a second lane in the road section, the first lane being adjacent to the second lane; the distress data comprises a rapid deviation in an x-y plane followed by a rapid return to an initial trajectory for a vehicle in the first lane; and the traffic data comprises a lack of any vehicles in the second lane at the traffic time component that corresponds to the distress time component. - View Dependent Claims (12, 13, 14, 15, 16)
