Re: [carfree_cities] One-way streets
Indeed, one-way streets (and streets with medians*) are anti-people.
Unfortunately in e.g. Manhattan, new, separated-bicycle paths are being
implemented on many of the wide north-south one-way Avenues. This has
done wonders for increasing bicycle modal share, but now many cyclists
are being "bike salmon
(phrase comes from Bike Snob <http://bikesnobnyc.blogspot.com/>), i.e.
riding against traffic, also illegally. It is of course the natural and
direct thing to do. /Who would ever suggest that pedestrians could only
walk one-way on any street anywhere?/ So these paths push the Avenues -
which were also two-way up until sometime in 1930's or so - further away
from where they should be and still NYCDOT/Janette Sadik-Khan/Michael
Bloomberg get lots of praise. Not sure if all of it is warranted.
Unfortunately the official - and vocal - cycling lobby there will not
bring this issue up, at least in public. To be fair, there are some
useful two-way bike lanes on certain sections of roads in NYC.
In many cities in Europe, in particular in Belgium, "contraflow cycling"
is allowed on small one-way 30km/h or slower streets (where all vehicles
mix). Some of these European streets ARE quite narrow and with no
parking on either side, so wide vehicles can truly only go one way on
them (of course there is a further option of not giving access to wide
vehicles at all, and by the way in Belgium wider cargo bikes cannot ride
legally against traffic) but most outside of the oldest parts of
historical town centres are actually three-vehicle widths, with two of
these for parking on either side. Most used to be two-way when used for
horses, omnibuses and before there was any need for parking. So legal
contraflow here is nice, but a compromise and sort of a historical
deceit. Many of these streets are 50km/h streets, in particular in
Central and Eastern Europe, and thus have no chance for legal contraflow
and little chance for a lot of cycling, or care-free
perpendicular-to-vehicular movement in the space between buildings (now
bastardized into "crossing the street" -- probably every mobility or
infrastructure definition needs a complementary semantic one!)
* In car cities, people like traffic islands as a safety solution but of
course the real one is bringing the shores closer together and/or
lengthening the green for pedestrians.

- One-way streets not only increase traffic speeds and convenience for
drivers, they are inherently unsafe for pedestrians.
All sidewalks have two-way foot traffic, but motorists only are thinking
'one-way' and don't look for pedestrians coming from the other direction.
Signs also often face only toward the one way, with blank faces on the other
Speed limits in all urban areas on streets that have all modes of traffic
should be no greater than the speed of cyclists, about 20-25 km (15 mph).
