Seems to me that speed limit signs wouldn't work as well as traffic
calming devices like, say, speed humps. As discussed around here in
years past, they seem to work in a couple residential neighborhoods
around here that used to suffer from fast cut-through traffic. And I saw
quite a few similar things recently in France. They didn't cause me any
grief while cycling.

Anybody here with more experience with them?

My limited experience supports yours.

On speed bumps, a little cut that will allow passage of a bicycle
tire is a nice touch. I don't know if that is the intended
purpose, but I do see them.

Anything where the vehicle has to pass within N inches of some
object seems to have a significant slowing-down effect on motor
vehicles.

Dunno what N is, but I have seen strategically-placed large (as
in containing a small tree) planters that worked well.

The ones I saw were staggered left/right so distance N would be
on the driver's side for one planter and the passenger side for
the next planter.

Thinking there would be pix of this all over the place, I Googled
a bit... but was surprised to come up empty.

I don't think the objective here is to calm traffic. These are
already relatively calm, "Neighborhood Greenways". I think the
objective is to institutionalize and maintain / further this
character. I for one am just pleased to see the city using its
authority specifically for the stated objective of making streets more
hospitable for bicyclists, in specific oppostion to the inclination of
the car culture.

I don't like speed bumps. Trees are nice.

Why swerve for a speed bump? The ones I've seen go completely across
the road; anything else would ludicrous. They do seem more effective
than a sign/fine for reducing the effective speed limit, however, I'm
not wild about them. There were a few on a commute I cycled for a few
years and riding over them was a minor nuisance. I might appreciate
them more if I lived near one.

I hate the car culture until I have to drive a car. Then I hate the
bike culture. Actually, I don't hate the car culture that much,
because on ordinarily designed roads, I don't have that much
interaction with cars while riding a bike. On the east side, however,
there is this "we're Amsterdam" thing going and the notion that there
have to be quasi-separate routes for bikes (still a mix of cars and
bikes}:

http://www.streetfilms.org/portlands-bike-boulevards-become-neighborhood-greenways/

When I ride over there, I make an effort to avoid the bicycle avenues,
except where they offer the shortest route (which is rare). I'd rather
take the direct route, and take my chances with the traffic.

A close family member is an engineer who used to work for the
city of Shanghai a bunch of years ago.

One day he was at a presentation (in English) by a bunch of
Australians on proposed solutions for their transportation
infrastructure.

Their push was for preserving the then-current overwhelming use
of bicycles.

During the presentation, one of the old hands in the traffic end
of things kept muttering something in Mandarin during the
presentation.

When it was all over, one of the Australian guys was asking what
was up with the malcontent.

Nobody wanted to tell him but it eventually came out what the guy
was saying: "You guys are so full of shit!... Have you ever
*had* to go *everywhere* on a bicycle?".

All the ones I've seen, the cut is for rain drainge, and it's smack in
the very center of the street!

When I say, "car culture", I'm talking about the sense that cars are
essential, and the entirety of our surface transportation
infrastructure (save for train tracks) are *for* cars (and obviously
they are!... Damn it!... well, but maybe [just *maybe*] not so much
anymore and going forward in Portland, Eugene, Corvallis... )

Culture Schmulture - let 'em have it. (Have you read my prolific

I am definitely inclined to avoid traffic - even where it exists and I
inevitably have to deal with it, I make myself scarce... separate.

The most progressive societies in the world are in Europe, but there
are elements in the US ahead of even them; just elements, though - and
they're marginalized and eschewed when not outrightly disdained by the
mainstream glorious violent conquest (god and football / support our
troops / 12 guns a minute sold legally / a Hummer in every driveway /
etc.) culture.

I didn't click it, but imagine it will say, "click here to download

and don't doubt you're right that it's messed up. Oh well. I don't
want to direct traffic. Maybe that's what make me so "what the hell I
might as well go for it".

I do that sometimes (when I think I've got better things to do than
ride bike), but now that I'm getting back in shape, and since Ride
Bike is shaping up to be what I've got to live for, and there are *so*
many places to go...

I agree. There's a rail crossing on my regular route, and nearby a
school. The road was wide enough that cars could pass bikes (even two
abreast bikes) without a problem. To give the pedestrians somewhere
else to cross (even though there is a pedestrian crossing with lights
just 100 yards up the road opposite the school), the road designers
added a traffic island. Now there is not enough room for one bike to
share the lane with a car, going passed that island.

When the island was first added to the road in particular, numerous
times a car would start to pass and then see the keep left sign and
island (this is at night) and panic brake next to me before swerving in
behind me to avoid running into the sign.

Oh yeah, I felt soooo much safer with that island being there.

They put speed bumps at an angle in the road? Someone should be fired
for that. There is one in a parking lot around here---I don't
believe it was intentional but the result of a weird layout.
The rolling effect is extremely unpleasant even when barely moving.

I go around them if I can, otherwise bunny hop them, but then I
sometimes drop the shoulder strap on my messenger bag if it bounces on
my back, and have to restore it.

I hit one the other day caught me by surprise - a short one with no
paint and dark asphalt - didn't even see it. Not a big deal (hit
worse bumps occasionally), but disconcerting. I do appreciate that
they're more effective slowing cagers than they are me, so there's
that.

They did that at the entrance to the local YMCA.

I'd take it beyond "extremely unpleasant" and call it dangerous.
First time I hit it (at walking speed), my head got snapped
against the window post.

There are lots of different design elements used for traffic calming.
There's no question that some have been misapplied, and many have
detriments that need to be understood. You want someone competent to be
doing the design work, as usual. Overall, though, I like the concept.

As I said, there are places I know that have used speed humps (not the
much sharper speed bumps) very effectively in residential neighborhoods.
They've cause no trouble at all on my bike, but they have greatly
slowed both the speed and the frequency of cut-through traffic, where
occasional radar enforcement had failed. The residents love them.

1972 in Eugene, Oregon, ice on the roads was so think the bumps
(and unused railroad tracks) were invisible. I was cruising along
comfortably. Suddenly my bike flew several yards sideways, and I kept
going straight _many_ yards on my butt.

I love speed humps because I can take them full speed on a scooter just
by standing up, and enjoy the noise of the tailgating car/truck
suspension bottoming out. :)

At least around here, Tucson, AZ, the fire and police departments really lobby against speed bumps/humps. They believe it makes it more difficult for them to drive fast over them in emergency situations.

On a bike my experience has been that speed humps (broad with a shallow rise) do not disturb a bike at all while speed bumps (narrow with a sharp rise) are really bad at all but the slowest of speeds.

Dan, if you think that Europe is so advanced why don't you move over there and get a direct view of it instead of reading BS about it?

A husband and wife, both "highly paid" engineers in Sweden can maybe afford a THREE ROOM CONDO. Most people including families have a single room condo.

I'm sure that you'd like that since your medical care is almost free.

Here you have interactions with cars. Plenty of people I ride with hate that. But it doesn't bother me hardly at all. Why? Because you have roughly the same problems with another car. So you just be careful and polite and almost all the other motorists do as well. Though I admit there are days when I'm cussing out drivers myself.
