1. A method for generating an approximation of vehicle position for use by a driver assistance application, comprising:

  • performing a map matching analysis to determine a closest point to a vehicle position on a polyline representation of a road;

    identifying a Bezier curve in a geographic database corresponding to the closest point to the vehicle on the polyline;

    projecting the closest point onto the identified Bezier curve to obtain an approximation of the vehicle position; and

    providing the approximation of the vehicle position to at least one driver assistance application.
