Paseo @ Linwood if anyone is interested.

Too bad they can't swap out the orbs for arrows so we can dump that ugly "LEFT TURN SIGNAL" sign.

The Left Turn was a retrofit

Well, the sign is the retrofit. Left turn signals without arrows aren't allowed anymore. My point is: swap out the orbs for left turn arrows so we can go back to just having the ornate pedestal.
The optically protected lenses were also a retrofit.

They both are. Originally that was a four-way through signal. Later on, when they added the overheads, they changed it to being a left turn signal and added the sign.

Not the rarest of the rare, but for anyone who's never seen what a U-turn signal looks like, here's one in Lake Buena Vista, Florida:

That's neat, but for the life of me I can't figure out why there's a doghouse for that signal.

Pretty poor placement of the doghouse signal pole and the "keep right" sign pole. Barely room for a bike rider to stay in their lane... The signal pole could have been placed between the bike lanes and the pedestrian walkway (and used one pole for both bike signal and ped head). Also, that dividing line between bikeway and walkway should've probably been white.

A bit off topic, but what exactly is the point of the blank-out sign there? It seems to serve no purpose. Then again, I don't live there, so maybe there is a hazard I'm not aware of...

If you're talking about the blank sign on the mast arm next to the green Mountain View sign, it's most likely an illuminated NO TURN or NO TURN ON RED display that only turns on when traffic facing the sign does not have the right of way or can't turn due to conflicts. It could also be an illuminated YIELD TO PEDS display.

If you're talking about the blank sign on the mast arm next to the green Mountain View sign, it's most likely an illuminated NO TURN or NO TURN ON RED display that only turns on when traffic facing the sign does not have the right of way or can't turn due to conflicts. It could also be an illuminated YIELD TO PEDS display.

There's a lot of questions that I have about this setup.  Likely those questions would be answered once the area gets more developed and we see the final orientation of the signals and the intersection as a whole.

The most likely explanation for the doghouse signal is that perhaps that was the signal head that was avaialbe in stock when the signal was ready to be installed.

But a really off the wall explanation would probably be to allow for bikes to turn right from the future median bike path on Jordan to northbound 85 (which has a bike lane).  This can only safely occur at its own phase, when both WB Jordan and NB 85 have red lights.  (EB Jordan could probably have green during this phase.)  At the same time, it would also be safest to prohibit right turn on red during this time, so the blank out sign would probably be needed for a no turn on red at this phase as well.  I see no other purpose for the blank out sign as the blank out sign faces WB Jordan and the peds cross to the left of WB Jordan, where left turns are prohibited.  I guess the "no turn on red" could also occur when peds are walking along 85's sidewalk or perhaps during rush hours, but this area seems so desolate that it is unlikely that they need any NTOR signage at all, except if the bikeway conflicts with motoring traffic.

Another qn I have is with regard to why is there even a median bikeway and crosswalk in the first place here?  It is an unusual design.  At least with Lake Ave further south, there appears to be a full median bikeway treatment for a while to the west of 85.  I do see that Jordan Pkwy further east has normal bike lanes and sidewalks on the right side of the street.  So at some point the bikes will need to transition from the curb to the median in some fashion.

Here is a GSV at Lake and 85.  85 has a green and Lake has a lit up no right turn sign.  No peds or bikes anywhere to be seen.  Oh and of course an additional doghouse bike signal.

I think this deserves quality (clarity [sic]).  I will crosspost onto a Utah category in Mtn West with the hopes that perhaps someone who lives nearby can check it out for us.

Yes, I understand that. When I say "the sign is the retrofit", I mean the signals on that pedestal were never retrofitted with left turn arrows, with the "LEFT TURN SIGNAL" taking the place of that retrofit instead. I'm saying that the orbs should be swapped out with left turn arrows, so we can dump the silly sign.

There are no bike lanes behind you in this view.  The opposing bike signal must allow left turns, right turns and zig-zags to stay through on South Jordan Parkway.  So it would be appropriate to either have a "NO TURN ON RED" blank out (or alternatively, a YIELD TO BIKES sign, if the state has an MUTCD supplement for opposing bicycle movements).

If I remember correctly, the aspects are:

- top: red bicycle
- top left: yellow bicycle
- top right: yellow right arrow
- bottom left: green straight arrow
- bottom right: green right arrow

Many moons ago, as a small child, I wondered why U-turn arrow signals didn't exist. I would see u-turn lanes signaled with left arrows and thought surely they could make a u-turn arrow. Recently they have started appearing around the Triangle of NC, and I am glad they finally listened to my idea  :)

And it's really appropriate to do so when U-turn is the only allowed movement.  We don't want folks making a left into the barrier, just because they see a green arrow.

Abandoned Krossgard Pedestrian Signal by freebrickproductions, on Flickr

Looks like the Krossgard pedestrial signal was made by Tru-Fit Screw Products, out of Cleveland, OH.  Tru-Fit Screw Products is still in business, but they no longer make the pedestrian signals.  Their web site is at http://tfpcorp.com/.

These might not be rare everywhere, but I have never seen these kind of pedestrian signals in Seattle (or anywhere in Western Washington) before.

Cross-posting from the 'Traffic Signal' thread:

Curious what people know about this Econolite pedestrian signal I found in Seattle the other day.

Album: https://flic.kr/s/aHsmWnx79t (there is a video in here showing operation including countdown timer)

I've never seen another one like it. It's very square with short visors around the edge.

It is at the end of the right-turn lane of the side road.   It is back since there is an island for that right turn.
