I would love to know if there's a tagging schema to hint at which direction
the green wave <http://en.wikipedia.org/wiki/Green_wave> rolls on a
street.  Tulsa is somewhat notorious for reintroducing two-way traffic on
streets timed for one-way, effectively creating a "red wave" in the
direction opposite the street's previous one-way direction.  There's quite
a few around work and I dogfood the map on routine trips to find hangups.
Ideally, the "red wave" direction would be penalized severely for cars and
bicycles, and incentivized for pedestrians (since walking the direction as
the motorist's red wave usually produces a pedestrian green wave (or very
near to it) by coincidence in many cities).
