Claim One:
1. A method for optimizing a display of a route map, the method comprising: fitting a collection of reference points in said route map with a probability distribution function, each said reference point corresponding to a position of an intersection in said route map; deriving (i) a position representative of said collection of reference points, (ii) a first farthest position in which a member of said collection of reference points extends in a first direction away from said representative position, (iii) and a second farthest position to which a member of said collection of reference points extends in a direction that is orthogonal to a vector between said representative position and said first farthest position; computing a bounding box, wherein a size and orientation of said bounding box is determined by said representative position, said first farthest position and said second farthest position; determining a direction of the long axis of said bounding box; and rotating said route map, by an amount that is sufficient to reorient said long axis so that said long axis lies in a predetermined orientation, to form a rotated route map.
