if you want to map the traffic sign, traffic_sign=low_emission_zone

if you want to map a kind of "barrier" for high emission vehicle,
I'm not sure if it's useful to create a key on all shared nodes between
the zone and the road.
but if the zone is not in osm or if the sign (sometimes placed at the
previous intersection) is not at the same place as the beginning of the
zone, it could make sense.
there should probably be an access restriction, because this also exists
for parking spaces
