A set quality index is determined based on position readings of set or based on position quality indices. A path length is determined based on mutual distances of consecutive position readings of set. The path length is determined using a digital road map (1') by associating position readings of set with road segments (S-1-S-4) having respective known segment lengths. The path length is determined based on segment length of the road segment. An independent claim is included for an onboard unit carried in vehicle.",
