Abstract
A method for generating a road map for vehicle navigation comprises: receiving an original road map having a crossroad junction, an inward lane entering the crossroad junction, and an outward lane leaving the crossroad junction; generating a reference path capable of guiding a vehicle driving from the inward lane to the outward lane through the crossroad junction; generating a polygonal hub that encompasses the crossroad junction, wherein the reference path enters and leaves the hub by crossing a first binder and a second binder, respectively; and generating automatically a type of the reference path based on the geometrical relationship between the first binder and the second binder.
