- Multiple lane markers on the same lane as in left;left|right
(ref. https://github.com/Project-OSRM/osrm-backend/pull/2697)
- you probably have to check this in detail as in: are there
situations and/or countries where it makes sense to have
multiple times _the same_ lane marker on a single lane.
What means "left;left|right" ? And what can be wrong with this ?
left;left|right means you have two lanes, the leftmost lane has two
arrows to the left (does this make sense at all? always mis-tagging?),
the rightmost lane has one arrow to the right.
Example for this tagging scheme:
http://wiki.openstreetmap.org/wiki/Lanes#Motorway
- Lane access tag values not matching turn lane tag values.
We do not already make inter lanes tag check yet, but make sense.
- Impossible or strange lane configurations such as the left
most lane turning to the right crossing straight/none lanes
(in right-sided driving countries).
This one, at least, look easy.
I completely rewrite the checks about lanes. Now it does not suppose any
thing and use lanes=[0-9] or other lane tags to extract the number of
lanes. It take me a while to do, especial to adjust the checks on
worldwide data.
- Bad lanes value : lanes=* is not an integer
- Conflict between usage of *:lanes or *:lanes:(forward|backward|both_ways)
- Conflict between lanes number, mismatch of total lanes number and
suffixed values (eg lanes:forward)
- Invalid usage of *:lanes:(backward|both_ways) on oneway highway
- Unknown turn lanes value
- Bad turn lanes order : eg turn right on left side...
- Conflict between lanes number of same suffix ('', forward, backward or
both_ways), eg turn lanes mismatch destinations lanes
- Bad access lanes value, should not be an integer but a restriction :
confusion between tags for restriction and lane number
- Turn lanes merge_to_* need an aside lane on good side : eg
merge_to_right need to be on the left side of the road

Plus and other check about "Bad lanes number or lanes:turn before and
after this node". Check around a way with turn lanes tags if the content
of the tag match the topology and the other turn lanes tags (this one is
the tedious one to setup ;) )
