Abstract: Methods and systems are provided for determining a road surface condition. In one embodiment, a method includes: receiving vehicle data; constructing, by the processor, a driver behavioral model based on the vehicle data; determining, by the processor, a surface condition based on the driver behavioral model; and generating a signal based on the surface condition.

Abstract: A method for acquiring road data onboard a vehicle, the road data associated with a segment of road is provided. The method obtains, via vehicle onboard sensors, sensor data associated with current weather conditions, current road conditions, and a physical road state; determines whether the current weather conditions indicate existence of severe weather, whether the current road conditions indicate potential slip, and whether the physical road state indicates one or more road anomalies; generates a road data result, based on existence of severe weather, potential slip, and one or more road anomalies; and transmits the road data result, via a vehicle onboard telematics unit.
