A controller of a vehicle obtains lane identifier information indicative of identifiers that define a lane of a road along which the vehicle will travel, determines distances between the lane identifiers at a plurality of different points along the lane based on the lane identifier information to obtain lane width information, determines a depth or distance from the vehicle to each of the plurality of different points along the lane using the lane width information and a known or assumed lane width to obtain an uncorrected lane topology profile, transforms the uncorrected lane topology profile to an inertial frame of reference of the vehicle based on a monitored orientation of the vehicle by a set of sensors to obtain a corrected lane topology profile, and controls an autonomous driving feature of the vehicle based on the corrected lane topology profile to proactively compensate for an upcoming road topology variation.
