A method for determining the geometry of a route section, using route points representing information about the route section, wherein route section data between at least three adjacent route point s are calculated, for determining a maximum possible speed for a vehicle traveling along the route section, is characterized in that a check is made to ascertain whether two adjacent route points f all below respectively predeterminable distances from one another and in the affirmative route section data through the se route points are calculated as a) straight line if the route points are arranged in a straight strip of predeterminable width, or b) arc of a circle if the route points are arranged in a constantly curved strip of predeterminable width and the tangent to the, in the direction of travel, first one of the route points is essentially located on a direction vector of the vehicle, or c) clothoid if the route points are arranged in a progressively curved strip of predeterminable width, wherein the geometry of the route section in the region of said route points is in each case determined in the form of the calculated route section data.
