Claim 17:
18. A method for determining road surface traction capacity for roadways located in a common spatio-temporal zone utilizing a plurality of vehicles that each include a plurality of sensors and system, the method comprising:
receiving, by one or more central computers that are part of a back-end office, a plurality of parameters from the plurality of vehicles, wherein the plurality of parameters related to road surface conditions in the common spatio-temporal zone and the plurality of parameters include a traction level for a selected vehicle of the plurality of vehicles that represents an ego vehicle, and wherein the plurality of sensors and systems produce a response indicating a condition indicative of the road surface traction capacity for the common spatio-temporal zone and the response is a high excitation context, a low excitation context, or both;
determining, by the one or more central computers, at least one of a perfect match value and a partial match value between two contextual data points between two discrete vehicles that are part of the plurality of vehicles, where the two contextual data points are part of the plurality of parameters; and
combining at least one of the perfect match value and the partial match value with the traction level corresponding to the selected vehicle to determine a road surface traction capacity value for the common spatio-temporal zone.
