I have not been following the details of the recent discussions about
Lyndale Avenue etc., but do want to concur in the implications of Mr.
Alberti's comment.  Having driven in a number of urban areas, I find that
the coordination of traffic signals within Mpls (and the metro area
generally) is horrendously done.  As others have commented here recently,
poor signal coordination not only increases congestion, it increases air
pollution (indeed, the last time I checked, signal coordination is one
legally recognized basis to reduce air pollution in EPA non-attainment
areas).

I also would suggest --largely from my own reaction (and I suppose this is
somewhat of a confession) -- that poor signal coordination contributes to
aggressive driving.  I am familiar with many stretches where one must drive
at 15 mph to time the light and then 45 mph to time the following light --
and when missing one light will result in hitting the red lights at each of
the next three, or four, or five lights.  Speaking for myself -- as the rat
in the cage--, this is my major source of stress when driving.  I prefer to
drive slowly and continuously to my destination.  However, the system
creates an incentive to drive erratically and magnifies the inconvenience
that is posed by the vehicle in front that dithers, stops to turn or wanders
into one's lane without signaling.

The point being, light coordination on one-way "boulevards" preferenced for
arterial travel is much simpler than it is for a two-way grid where
preferencing is nearly impossible.  I expect that most drivers would gladly
trade off velocity for more continuous travel, and that traffic engineers
would tell us that more continuous travel yields equivalent capacity at a
lower speed limit.  Thus, it doesn't seem to me that a strategic grid of
one-way streets within the city needs to constitute a set of "concrete
highways," but that a boulevard concept, with 25-mph speed limits, traffic
calming devices, and the like can be quite compatible with both residential
and pedestrian-scale retail while providing ample capacity.

Subject: [Mpls] one and two-way streets

Here's the experience I have every Saturday, when I drive my daughter from
Cooper neighborhood to the Minneapolis Institute of Arts:

I drive west on the one-way 26th street from Hiawatha to 3rd Ave.  If I
drive at 28 MPH I rarely have to stop (usually at Portland).

I return east on the one-way 28th street from Nicollet to Hiawatha.  At 28
MPH I likewise rarely have to stop (usually once at Chicago).

The amount of time I spend crossing the city on the one-way 26th and 28th
streets is EQUAL to the amount of time it takes me to drive the three blocks
south on bidirectional Nicollet Ave. to get from MIA to 28th St.
