Abstract:
1. A computer-implemented method for representing multiple road dimensions with a single multi-dimensional parametric spline curve, comprising in combination: creating, by a controller, a first spline vector to represent an initial dimension of a road segment; identifying at least one additional dimension of the road segment to add to the first spline vector; identifying a process for creating the at least one additional road dimension so that the at least one additional dimension is compatible with the first spline vector; executing, by the controller, the identified process to modify a second spline vector associated with the at least one additional road dimension; adding the second spline vector associated with the at least one additional road dimension to the first spline vector as a combined spline vector; and storing the combined spline vector including the initial dimension of the road segment and the second spline vector associated with the at least one additional road dimensions in a database.
