Claim Text:
1. A method comprising: receiving a geographic location of a vehicle; receiving a reaction profile of an operator of the vehicle; determining, using a processor, a roadway condition based on the geographic location of the vehicle; calculating an optimal warning distance from the roadway condition based on a braking distance of the vehicle and the reaction profile of the operator; and alerting the operator or a navigation system of the vehicle to the roadway condition when the vehicle is located at the optimal warning distance; wherein the reaction profile includes a vehicle computed reaction time of the operator of the vehicle, the vehicle computed reaction time selected from a database comprising a plurality of times from historical probe data that an operator adjusted a velocity ahead of a roadway condition, wherein the roadway condition is a scenario for which the vehicle reduces speed for safety.
