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

  • performing, by a processor, a map matching analysis to determine a closest point to a vehicle position on a polyline representation of a road derived from one or more Bezier curves stored in a geographic database;

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

    projecting, by the processor, the closest point to the vehicle position on the polyline onto the identified Bezier curve to obtain an approximation of the vehicle position; and

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