Abstract (en)

The present invention relates to a method for anticipating a pathway (3) of a light rail vehicle (1) ahead of a turnout (2) by excluding pathways (3) of possible pathways (3) by inspecting flangeways (6) of the possible pathways with detection means (8) and determining the possible pathway if the flangeways (6) continue throughout the turnout (2), and/or determining the anticipated pathway (3) if the speed of the vehicle (1) is higher than an allowed speed of a possible pathway (3).
