Abstract
Methods and systems for assessing the effect of road curvature on the travel time and the comfort level of a path determined by a ground based route planning system. The methods and systems identify a path and determine an allowable speed profile of the path, wherein the allowable speed profile satisfies a cross track acceleration constraint. Thereafter, the methods and systems determine an optimal speed profile of the path, wherein the optimal speed profile satisfies both an along track acceleration constraint and a speed constraint. Using the optimal speed profile, the road curvature of a path may be factored into a determination of the traversal time of the path. Additionally, using the optimal speed profile, the road curvature of a path may be used to derive a comfort level of the path. The optimal speed profile may be further used to provide driver assistance.
