1. A system for performing a lane hazard mitigation algorithm comprising:
a sensor for detecting a first hazard in a host road lane and a second hazard in an adjacent road lane;
a processor for determining a host lane mitigation including a host lane speed reduction in response to the first hazard, wherein the host lane speed reduction is proportional to a magnitude of a roughness of the host road lane, and an adjacent lane mitigation including an adjacent lane speed reduction in response to the second hazard, wherein the adjacent lane speed reduction is proportional to a magnitude of a roughness of the adjacent road lane; the processor being further configured to generate a lane change control signal in response to the adjacent lane speed reduction being less than the host lane speed reduction and to generate a vehicle speed reduction control signal in response to the host lane speed reduction being less than the adjacent lane speed reduction; and
a vehicle controller for controlling a lane change maneuver of a host vehicle from the host road lane to the adjacent road lane in response to the lane change control signal and for reducing a host vehicle speed by the host lane speed reduction in response to the vehicle speed reduction control signal.
