Title: Which states' traffic light design do you like best, and why?
Post by: KCRoadFan on April 22, 2022, 12:41:31 AM
Throughout my travels, I've noticed that many states seem to have a distinct (or at least commonly seen) style of traffic light, such that I would recognize it as being within that state. Among these designs, here are a couple I especially like:


Those are two of the states that I like the most regarding their traffic-light installations. As for you all, what states do you think do best with their traffic lights?

I'm personally a fan of states that fall into the camp of "Left turn signal goes over the left turn lane", even if it's not protected.

One example that comes to mind is Minot, North Dakota, a town in a state that's really good at this.
https://www.google.com/maps/@48.2258886,-101.2960759,3a,39.4y,182.74h,96.65t/data=!3m6!1e1!3m4!1sPsA3WQwTLujwx3Ca0AhLUg!2e0!7i16384!8i8192

Some jurisdictions in Illinois (cough cough, not district one) do this great as well. District 3 installed this example.
https://www.google.com/maps/@41.5095672,-88.4334757,3a,37.6y,351.83h,92.04t/data=!3m6!1e1!3m4!1shS5tEr47PsK0C2z1onR52A!2e0!7i16384!8i8192

Alaska too.
https://www.google.com/maps/@61.1953387,-149.7630333,3a,48.8y,264.85h,96.9t/data=!3m6!1e1!3m4!1sFeu3McsAdqmwZJZFb1809g!2e0!7i16384!8i8192

Alaska and North Dakota also don't put all of their thru signals on the mast arm; I personally think having an overhead signal and a supplemental far side right signal is a more effective combination than two signals on the mast arm, especially when trucks have the potential to block both overhead mounted signals. It's a practice I think more states should follow.

I really like Wisconsin's:

- Horizontal overhead signals. Probably just my bias seeing them in Japan and Taiwan a lot, I prefer them to vertical ones.
- Constant supplemental signals, including near-side ones. Personally, I think near-side supplementals are important, but it seems like 40 states disagree with me.
- Only 1 or 2 signals overhead, with the rest as supplementals/vertically mounted. Reduces overhead clutter, unlike some other states that put every signal for every lane overhead and nothing on the sides.

Runner-ups for me are Illinois and New Jersey. Illinois have the same features as Wisconsin, minus the horizontal overheads. NJ lacks vertical supplementals compared to the other two, but I like their clean mast-arm layouts (like WI and IL) and near-side overheads.

I guess I like VA, or at least their state-maintained signals.  Their newer ones are consistently mast arm and have green road name signage in the upper right corner every time.  FL's horizontal ones aren't too bad either.  And CA's are nice as well.

How do you feel about Wisconsin going forward, knowing that the horizontal installs are becoming a thing of the past in favor of the newer monstrous installs?

I'm partial to Nevada's layout.

Vertical signals on mast arms. New installations are typically signal per lane.  Far side post-mounted supplemental signals standard, with larger intersections having near side post mounted supplemental for thru and overhead near side for left turn signals.

I'm also okay with an older Nevada standard, still common in the Vegas area (and is a common practice in some areas of California): basically identical to the above, but when there is more than 1 left turn lane or more than 2 thru lanes, then the number of overhead signals used is typically <number of lanes> minus 1.

But overall, any non-spam wire installation where there is at least two signal heads per phase will be sufficient to me.

Looking through Milwaukee a bit (as I heard that's where most of the newer monstrous installs are), I don't like them as much as the older layouts. Personally, I don't like having 1 overhead signal per lane, as that clutters the overhead for wide roads, and makes the mast arm long. Much prefer a "cleaner" overhead by having 1 overhead for every 2 lanes or so, and the rest as well-placed supplementals (at least a near-side and far-side). But at least they kept the near-side supplementals!

A large part of me wants to say Michigan, because I love those backlit regulatory sign boxes, and I actually like the span wire installations and the multiple signal faces hung from a single support.  This is a good example: https://goo.gl/maps/8EfStatsWe3ygUhH7 .  Unfortunately, those backlit sign boxes are prone to fading: https://goo.gl/maps/LbsK1eQpnngYqzwNA .

Another favorite is New Jersey, because I love the trusses (although they aren't everywhere), and it's helpful that most of the street signs on state and county routes have both the shield and the street name, and I think the "backwards-facing" traffic signals are a good idea (and they help with Vienna Convention compliance, if anyone cares).  Here's an example that has all of the above: https://goo.gl/maps/kUhNWmRzQkzX6cxB9

Honorable mention goes to Texas, simply because I love horizontal traffic lights, and sometimes they do some other good things.

I like them too, what with the bottom wire that helps stabilize the signals. I don't remember having seen that particular installation in any other states; you would think that hurricane-prone Florida and South Carolina, where span wires are common, might want that extra stability.

There's a signal on US 51 in DuQuoin, IL that looks like it was based on the standard INDOT spanwire design (https://goo.gl/maps/8kfDBmesJiPhLDG69)  Most other span wire installs in Illinois use a two wire design:

* Example in downtown Belleville (https://goo.gl/maps/GsA5Ef16vL6umSVZ9)

* Another example in downtown Belleville (https://goo.gl/maps/PF3upJhvgg1V6UUL7)

* Example on NB IL 29 in Peoria (https://goo.gl/maps/F4mmcTRwBQMveVfj6) (IIRC this one was supposed to be replaced with a standard mast arm)

The temporary span wire signals usually used for construction projects in Illinois also use two wire but usually have more sag.



Missouri also uses a bottom wire for permanent span wire installs:

* Example on MO 30 near St. Louis (https://goo.gl/maps/BADLtcC8LaBduoBc7)

* Example on MO 141 (https://goo.gl/maps/i9pT1YNSvJJhKJ8D6)

* Example on US 67 (https://goo.gl/maps/9DjiMckyBcjpTAFL7)

There's some places in VA that have the bottom wire on wire spans, but they're slowly going away (mostly because they've been getting replaced with mast arms, which is the VDOT standard nowadays). And I'm definitely talking about VDOT installs as the cities rarely use bottom wires.

Still not nearly as clean as IN or OH though.

I like how the US-51 example still follows IDOT standard practice of a far side left supplemental for left turn signals. I wish more states would do this, even if they use span wires.

I work a decent amount in DuQuoin, so I am familiar with that signal. IDOT has since fixed it, but for about 6-9 months the last calendar year, one of the Towers (I believe the SB Traffic Tower) was no longer vertical - was about a 70 degree offset from the span wire instead of a vertical 90 degree. Not sure if it was wind caused or an overheight vehicle struck it, but its history now since IDOT has fixed it back to vertical

That signal is the only span wire installation in DuQuoin. The other signals along US 51 (only thru road with signals in town) are all standard IDOT mast arms

Still unusual to see an Indiana-style span wire installation with 5 section towers instead of doghouses, but it is IL so no on the doghouses!

I have long been partial to California and Illinois, but lately, I've come to appreciate New Mexico a lot. I actually like the horizontal signals, but they use a ton of supplemental signals too, and generally only use one or two overhead signals even on wide roads (my preference). I also like that they don't use backplates for their post-mounted signals.

What's wrong with having backplates on a post-mounted signal? I can maybe understand when a signal head is mounted on the side of a mast, but I prefer a free-standing post-mounted signal head to have a backplate so it's easier to see.

The thing I don't like about New Mexico is that at least in Albuquerque, the vast majority of left turn signals are post mounted at the far median or far left corner, and rarely ever overhead. Those are great as supplemental signals but there really should be a primary overhead in my opinion. More than once I've nearly run a red on a left turn in ABQ because I was looking only at the overhead green thru signals and almost missed the red arrow on the far median post.

To be totally clear, I don't dislike backplates on post-mounted signals. It's a very minor preference of mine to not have them. It's entirely aesthetic, as I find post-mounted signals without backplates tend to have a slimmer appearance, and can be bunched together a bit easier. They also tend to be less likely to get hit, or have their backplate torn off or damaged.

Interesting. Many protected-only left turns in British Columbia are post-mounted only, including an eye-level near-side signal. So in this way, I'm very used to seeing left turn signals mounted only on posts and don't find it unusual. So there may be some bias here, but in both ways, as Utah and Georgia almost never use post-mounted signals (except at SPUIs in Utah) and so you may be less likely to watch for them. Maybe. Don't want to assume anything, of course.

I actually like California mast arms the best as far as looks. New York City, is the worst as the Double Guys are so old.  Even California removed the double guys for the modern look.


I grew up in NJ where mast arms and side mounts were often interchangeable and mixed up, so variety was a thing I was accustomed to.  However visiting states like California where things were standard (except SF as they were not into overheads and back plates) with the same bent arms, back plates, and side mounts were interesting as well as it was different from NJ.

Perhaps. It's certainly not an ingrained habit of mine to look for them. I will say  though that I've done a fair amount of driving in much of the western/central/southern US and I can't recall another jurisdiction that regularly omitted left turn signals from the overhead wires/mast arms the way ABQ does.

Although the effect on drivers is probably less, this is even more true of right turns in NM. I have never seen a horizontal 5-section right turn signal in NM despite that state's almost exclusive use of horizontal signals. Usually the only indication of a protected right is on one 5-section signal on the far right post.

I'm biased, but I think MA has the best signal design. Lots of right turn on red restrictions, pedestrian friendly phasing with either LPIs, concurrent protected phases, or exclusive pedestrian phases. Lots of bicycle traffic signals as well. They're also big in FYAs, which I also think is great.

Aesthetically, the signals are almost always all black with a reflective border. Personally, I think all black without the reflective border is the best looking, but the reflective border doesn't take away from that.

I would say, genuinely, that the closest comparison would be British Columbia, and maybe Wisconsin. It would have to be a jurisdiction that regularly employs medians. So like here in WA, they would have to be rare simply because medians at intersections are really rare. But in BC, WI, and NM, they're much more common. Ergo, much easier to use/rely on post-mounted signals in the median. Although in British Columbia, it's mostly reserved for protected-only left turns.

I know in California, it's pretty rare to see 5-section right turn signals placed anywhere but on the signal mast, or post-mounted. Overhead-mounted 5-section right turn signals are virtually unheard of. May also be true in Arizona. Also true for a couple cities here in Washington.
