Title: Is a sign better with one or two posts?

It depends of the wind loading area of the sign and the type of post used.  Bigger signs usually require 2 posts and there is a cost savings of using 1 post is 2 are not needed.

I prefer one signpost for all of those. I also prefer one bar for signing two routes in a concurrency, by either stacking the shields or placing them side by side. Unfortunately, this is a foreign concept to Ohio DOT, as the main way of signing concurrencies here is with a separate signpost for each shield.

If the pole was strong enough, 1 pole would be appropriate there.

The horror! Those heathens at NCDOT, daring to put up a simple warning sign on one standard sign post.

The very first two examples you linked to aren't even made of the same material:  one has metal posts and the other has a wooden post.  That's not exactly a fair comparison to start out with.

But the answer is actually four (https://goo.gl/maps/fKVBK5WBhDjqJBeu6).

Where's that Arizona detour sign that had 8 posts? I've been trying to find it, but I can't. Could've sworn it was in the Worst Signs thread.

I seem to recall that when I visited in 2002, the welcome sign wasn't much bigger than this and had five or more posts. I have a paper photo somewhere I might be able to dig out and see for sure.

In terms of non-guide signage, I have not seen the two-post setup here in WA. Warning, regulatory, etc...all single-post.

I definitely prefer the look of a single post.

Which states post interstates reassurance shields with two posts? Ohio is one of them to start the list off, though there's also a fair share of single-post ones (specifically some newer installations) out there.

Massachusetts has wide reassurance shields and uses 2 posts.

That's a guide sign and all have at least two posts that I've seen. Apart from little green signs.

A lot of newer MD installations are 2-post as well - for example, just about every I-95 shield on the MDTA-controlled JFK Highway segment looks like this (https://www.google.com/maps/@39.6425585,-75.8135386,3a,32.2y,283.48h,85.96t/data=!3m6!1e1!3m4!1sXzI3eWS_k1X_9GJ5I5al2g!2e0!7i16384!8i8192!5m1!1e1?hl=en) (for comparison, here's an older 1-post shield (https://www.google.com/maps/@39.1808106,-76.7841491,3a,46.4y,81.01h,87.31t/data=!3m6!1e1!3m4!1spTbYbO1asaw_MVU_heTZFA!2e0!7i16384!8i8192!5m1!1e1?hl=en) on the SHA-controlled "between the beltways" segment).  And here's a snazzy-looking newer 2-post on I-270 (https://www.google.com/maps/@39.3168347,-77.3525602,3a,64.6y,186.46h,85.42t/data=!3m6!1e1!3m4!1soeVzA5c7XxzHa-ZHUSzNfA!2e0!7i13312!8i6656!5m1!1e1?hl=en) from SHA.

Oklahoma is generally only one post, though there's a few doubles on I-240 (https://www.google.com/maps/@35.3915071,-97.5372517,3a,40.6y,297.5h,88.32t/data=!3m6!1e1!3m4!1sZolw8n3_wNpzJoO7JSWRBg!2e0!7i16384!8i8192?hl=en) (probably because of the wide shield plus assorted concurrency shields under it).

I think this (https://www.google.com/maps/@35.2981351,-78.5964398,3a,30.1y,247.22h,83.61t/data=!3m6!1e1!3m4!1sn5LMLZKY6dpsvcLXknalvg!2e0!7i13312!8i6656?hl=en) is excessive with 13 red diamonds. NC-55 used to go straight through where the I-95 Northbound entrance ramp is.

Especially the two on the left.
6 would be enough, right?

In Kentucky, it generally depends on the size of the sign. The typical 24x24 or 24x30 route markers, square warning signs, rectangular regulatory signs, etc., are usually mounted on one post, especially on two-lane roads.

On the interstates, parkways, and high-speed four-lane roads, most of the signs are mounted on two posts. Some of the route markers only get one post, however.

One and two posts with reflective material (https://www.google.com/maps/@36.1319728,-79.2238626,3a,75y,303.81h,85.51t/data=!3m6!1e1!3m4!1snKbMKpPwIzXJ19w5tgQA7w!2e0!7i13312!8i6656)

Here aswell. (https://www.google.com/maps/@36.1307155,-79.2215393,3a,75y,307.8h,87.81t/data=!3m6!1e1!3m4!1sUBE1GqpMaMYp24MziqyRzQ!2e0!7i13312!8i6656)

These are in my neck of the woods.  The double stopsigns and the double approach signs appear to be the new standard for NCDOT District 7.  This intersection was changed over to a four-way stop ("all way") a couple of years ago.  If you notice, the opposing direction also had the double stopsigns, but still had the single approach sign on GSV.  After the change, all four directions now have both double stopsigns and double approach signs.  There are now a few locations that have the wider stopsign posted on the left side for better visibility in right-hand curves.

As is typical in North Carolina, both sets of changes were instigated after fatal accidents.  The one back in 2015 ended up with changes primarily in the westbound direction.  The next one was a few years later, and I'm pretty sure that it was in the same direction.  That resulted in the four-way stop.  High Rock Road has been the "main road" out here since it the final section of dirt road was paved in 2001.  But most of the traffic turns north or south on Mill Creek Road to access those subdivisions.

Do you prefer signs on just the right side or on both sides?

There's signs with two posts here.

A lot of it depends on the size of the sign being mounted. Smaller signs can get away with a single post, while larger ones often require two.

West Virginia's standard is to use Z-bars with signs mounted on two posts, but not on signs mounted on a single post. What you'll often see, especially with larger contractor-installed signage, is that they'll use two posts with Z-bars if there is no guardrail present. If the sign is located behind guardrail and does have crash safety concerns, they'll use two U-channel posts back-to-back and skip the Z-bars.

Wouldn't two posts be enough for this sign?

Actually three is not enough. The entire back of the sign needs to be covered with posts for it to be enough.

Those look like thinner posts that what would be used for a 2-post BGS.
