It is proposed to provide a system for localizing a vehicle in a marked environment, provided with a set of markers, e.g. on a road side, the markers emitting a position signal indicative of a respective marker's known geographical position. The system comprises a distance detection unit and a processing unit provided in the vehicle, the processing unit adapted to receive said position signal of a respective marker. The processing unit is adapted to receive said known geographical position from the position signal of said respective marker; and to estimate a coarse distance measure of the vehicle relative to the respective marker based on a position signal measurement. The processing unit feeds said estimated coarse distance measure to the distance detection unit; the distance detection unit being adapted to detect said marker within the coarse distance measure by a fine distance measure. The distance detection unit is further adapted to provide the processing unit with the fine distance measure of the vehicle relative to the detected marker and with a detection angle of the detected marker; and the localization unit calculating an instantaneous geographical position of said vehicle from the fine distance measure; the detection angle and the marker's known geographical position.
