* Trajectories of a particular GTU are not explicitly tied together. Not only would this involve quite some
* work, it is also impossible to distinguish a lane change near the start or end of a lane, from moving
* longitudinally on to the next lane. The basic idea to minimize overlap is to remove all positions on the
* previous lane beyond the lane length, and all negative positions on the next lane, i.e. all between ( ). This
* would however create a gap at the lane boundary '|'. Allowing one event beyond the lane length may still
* result in a gap, l->o in this case. Allowing one event before the lane would work in this case, but 'e' could
* also fall between an 'o' and '|'. At one trajectory it is thus not known whether the other trajectory
* continues from, or is continued from, the extra point. Hence we require an extra point before the lane and
* one beyond the lane to assure there is no gap. The resulting overlap can be as large as a move, but this is
* better than occasional gaps.
