1. A method comprising:
- receiving a geographic location of a vehicle or associated device;
receiving a roadway traffic condition based on the geographic location, the roadway traffic condition associated with a traffic build-up downstream of the geographic location based on traffic data;
identifying a braking distance for the vehicle;
identifying a personalized braking distance for a user associated with the vehicle;
calculating an optimal warning distance based on the roadway traffic condition downstream of the geographic location, the braking distance of the vehicle, and the personalized braking distance of the user; and
providing a message for autonomous or assisted driving to the vehicle for operation of the vehicle in response to the optimal warning distance.

Abstract
Systems, methods, and apparatuses are provided for determining an optimal warning distance for a vehicle. For example, the geographic location of the vehicle is received along with a reaction profile of the operator of the vehicle. Based on the geographic location, a roadway condition is determined. An optimal warning distance is then determined based on a braking distance of the vehicle and the reaction profile of the operator of the vehicle. The operator of the vehicle, or a navigation system of the vehicle itself, is alerted to the roadway condition when the vehicle is located at the optimal warning distance.
