1. A method for partitioning a widened area of a traffic lane bounded by two edges through which a vehicle can be driven by a driver in an automated manner along a reference path traveling in said traffic lane, said vehicle comprising an aid for laterally positioning said vehicle relative to the reference path, said method comprising the steps of:
detecting a next splitting of said traffic lane into at least two new lanes;
determining a widened area of said traffic lane;
determining, in said widened area, at least two reference paths each of which is capable of reaching one of the new lanes;
calculating a longitudinal distance relative to the beginning of said widened area, said longitudinal distance being a function of the reference paths and the edges of said traffic lane;
determining a first sub-area of said widened area extending along said widened area from a beginning of said widened area for said longitudinal distance; a second sub-area of said widened area being determined as a complement of said first sub-area relative to the widened area, said second sub-area extending from an end of said first sub-area to an end of said widened area.
