Les informations routières (16) concernent des points d'orientation (11, 12) situés sur le trajet. Chaque point d'orientation est défini comme étant un endroit où le véhicule peut continuer sa route dans plusieurs directions. Les informations transmises sur chaque point d'orientation (11) comprennent: des données de localisation (25) qui déterminent la localisation (I11, b11) du point d'orientation (11); des données (26, w1, w2, w3) concernant la géométrie du croisement situé au point d'orientation; des données de transition (22, 23) qui définissent le trajet à travers le point d'orientation (11).
