position defines where an event has taken place in relation to the road: e.g. driving lane 1, hard shoulder, central reservation, etc.

NOTE The driving lanes are numbered according to the usual local practice, i.e. driving Lane 1 is the lane nearest to the hard shoulder. In countries which drive on the left, driving lanes are hence numbered from left-to-right, and in countries driving on the right, from right-to-left.

NOTE Position is an event element and NOT a location reference element.
