1. A method for assessing road curvature of a path, including a plurality of waypoints, said method comprising the steps of:

  • a) determining an allowable speed profile of the path, wherein said allowable speed profile includes an allowable speed for the each of the plurality of waypoints, wherein the allowable speed for the each of the plurality of waypoints satisfies a cross track acceleration constraint; and

    ,b) determining an optimal speed profile of the path, wherein said optimal speed profile includes an optimal speed for the each of the plurality of waypoints, wherein the optimal speed for the each of the plurality of waypoints satisfies both an along track acceleration constraint and a speed constraint, wherein said speed constraint is a minimum of the desired speed and the allowable speed.
