Claim Text:
1. A method for estimating road friction conditions using vehicular participative sensing systems, said method comprising: providing data about road friction conditions by a plurality of participative sensing system vehicles; collecting, on a server computer including a processor and memory, the data about the road friction conditions from the participative sensing system vehicles; analyzing the data about the road friction conditions, by the server computer, to determine consensus road friction estimates; issuing road friction advisories from the server computer to advisory-receiving vehicles and other entities, where the road friction advisories include the consensus road friction estimate for a particular road and location, including issuing advisories of low-friction conditions to a road commission which has responsibility for a road on which the low-friction condition exists, and the advisories to the road commission include advisories of low-friction conditions needing immediate attention including snow plowing and road salt, and electronic sign message content, and advisories of chronic low-friction conditions needing long-term attention including road design changes and permanent road sign changes; using the road friction advisories as input to traction-related systems in the advisory-receiving vehicles; and notifying drivers of the advisory-receiving vehicles of any low-friction conditions described in the advisories.
