Title: Black Background Overhead Signs
Post by: talllguy on May 10, 2014, 03:57:02 PM
I haven't seen too many overhead signs using the full black background, with white Clearview. This one is at the Fort McHenry Tunnel toll plaza for southbound traffic (I-95 Baltimore). How is the black background meant to be used?

Once upon a time, VDOT had all the signs for the reversible center carriageway on Shirley Highway (originally I-95, later mostly I-395) in a white-on-black scheme to help distinguish them from the BGSs over the main lanes. I always liked it. They were gone by the 1990s.

This is the only photo I can find. Of course in a black and white photo it's hard to distinguish the color, so please take my word for it that it was a black background.

The following Street View link shows the last remaining white-on-black sign I'm aware of through there. This area no longer looks like what's shown here due to construction, but this sign was still there as of a few weeks ago. I'm not sure it will survive the construction, though. A corresponding red "Do Not Enter" sign nearby facing the other way was recently replaced with a current-style one.

I know there used to be black guide signs in California, but I can't remember where there are pics of those. Whenever jake (agentsteel53) gets back I'm sure he'll post some yummy black sign goodness.

+5 for black background sign
-10 for Clearview
-99 for negative contrast Clearview
-499 for negative contrast Clearview with numbers
-50 for Clearview numbers

Ugh. This is why I hate Clearview.

White on black is the same as black on white = regulatory signage. The MUTCD doesn't really specify when to use one or the other, but just about all of the example signs are black on white. The black signs I usually see are for truck weight restrictions (CT in particular).

I'm going to take a few points off for over-italicizing EZ Pass. It's not bad, and I'm sure some will argue it's fine. One agency (can't remember which one) had so italicized EZ Pass on a few signs it was nearly unreadable.

Doesn't a white-typeface on a dark background meet the FHWA's positive-contrast requirements for Clearview?

Quote from: FHWA - Design and Use Policy for Clearview Alphabet
The use of Clearview as an alternative to the Standard Alphabets is allowed only on positive-contrast (white legend on a green, blue, or brown background) guide signs, as this contrast orientation is the only one that has demonstrated an improvement in legibility distance to date for those legends composed of upper- and lower-case letters when using specific series of Clearview lettering. The use of Clearview in negative-contrast color orientations, such as on regulatory and warning signs, has been shown to decrease legibility distance when compared with the FHWA Standard Alphabet series.

So they don't specifically mention black but legally white on black is positive-contrast.

EDIT: Also not seeing anywhere on the Clearview policy that specifically negates the use of Clearview numerals outside of route shields.

EDIT 2: Nevermind, section 11.   :-|

This is located on northbound I-5 north of Los Angeles.  While the black sign may be construed as a guide sign, one could argue it's a regulatory sign because it instructs all trucks exit the mainline and use the bypass.

Googling, I see something about a toll booth replacement project at that tunnel, so presumably the orange background is a coverup because construction has temporarily changed the numbers of the lanes trucks use. But those are just armchair guesses.

White-on-black is indeed for regulatory signage, but I don't think the contrast reversal option has been available for that signing category in the MUTCD since the 1971 edition.  Also up until 1971, white-on-black could be used for guide signing on both conventional roads and freeways/expressways, except for Interstates.

There are only two regulatory-sign applications I know of where white-on-black is still used:  night-related signs (e.g. the night speed limit sign), and truck-related signs, such as the one shown in the OP's picture.  I agree that the sign as fabricated meets the positive-contrast requirement of the Clearview interim approval memorandum, but it doesn't meet the requirement that Clearview be used only for guide signs.

White on black is an option, but not mandated, for the R13-1 "All Trucks Over XX Tons ....." sign normally used in advance of weigh stations.   Most states (Massachusetts included) have used that color combination on such signs for emphasis.

I believe that the freeway restriction went away in the 1971 MUTCD, but the conventional road one persisted until 1978.  at least, I know for a fact that black-on-white (the opposite of what we are talking about) was okay until 1978.

personally, I've seen black guide signs surviving in CA, MI, NJ (Alps can tell you that they are "dark dark dark green" but I disagree), PA, LA, and probably a handful more states which I'm not recalling offhand.  the LA example is for the Superdome and dates to ~1966 when it opened.

I've seen white signs with black text in at least 30 states, albeit some were very very minor items like bridge name identifiers.

I thought it was reasonably well-established that the universe of discourse was guide signage.

that said, I wonder how many places used black background regulatory signage.  CA comes to mind of course.

I don't have any photographs, maybe someone out there does, but the Illinois State Toll Highway Authority used to have white-on-black button copy signage for the toll plazas and the separation between the Manual (attended) Lanes and Automatic (coin basket) Lanes over the road up until the late 1980s.

That sign needs to put out of its misery -- it looks as though it was green and then they painted over it with black. And now, it's wearing off and thus looks terrible.

Also, the sign looks like an a la carte setup. The letters are split up into two or three and then the arrows are all alone as well.

What is up with that? How old is it?

That is a New Jersey Turnpike CLASSIC!!! (late 1950s? 1960s? Around there IIRC) These are some of the oldest guide signs on the Turnpike, especially with that gantry (I-beam?). NJTA recently took one of these down near Exit 6, and this one is probably gone too. But this sign looks like it's still in great shape, and I hope it's still there.

I remember reading in the "Big Roads" book that black guide signs were tested alongside green and blue guide signs, to see which provided the greatest visibility.

Frankly, I am surprised green won. I find white on black more legible due to having more contrast, and I just think white on black looks nicer.

To me, green against green landscape mixes too much, so I too have no idea why green won.

Personally, I find big blue signs to be the best looking, in a purely aesthetic regard. Blue signs contrasted by green trees seem to be a nice contrast:

I still read m.p.h. as "m dot p dot h dot".

Regardless of my odd pronunciation, I would read that as a night (truck?) speed limit, though I'm guessing, as with most of the signs in this thread, it's an antique from the stone age of the MUTCD?

Quote from: J N Winkler on May 15, 2014, 10:00:09 AMAlso up until 1971, white-on-black could be used for guide signing on both conventional roads and freeways/expressways, except for Interstates.

I believe that the freeway restriction went away in the 1971 MUTCD, but the conventional road one persisted until 1978.  at least, I know for a fact that black-on-white (the opposite of what we are talking about) was okay until 1978.

personally, I've seen black guide signs surviving in CA, MI, NJ (Alps can tell you that they are "dark dark dark green" but I disagree), PA, LA, and probably a handful more states which I'm not recalling offhand.  the LA example is for the Superdome and dates to ~1966 when it opened.

I've seen white signs with black text in at least 30 states, albeit some were very very minor items like bridge name identifiers.

The Superdome opened on August 3, 1975.  Could that sign be dated to then instead of 1966?

As best as I can think of this is the first time I've seen use of the phrase "Pool Cars". Is that common for that region?
Not anymore. That photo dates to the 1970s. Around 1982 they switched to saying " HOV."

At the risk of going off-topic, do any "HOV 4+" restrictions exist anywhere anymore? From 2002 is this interesting tidbit:

QuoteThe U.S.-Mexico border crossing near San Diego (CA) has the only HOV 4+ lanes in North America.

The "4 Rider Pool Cars" sign I posted on the first page of this thread became an HOV-4 sign (they didn't start calling for that plus sign until much more recently) around 1982 or 1983 and it was changed to HOV-3 (which it remains) some years later. The other HOV-4 restriction in our area, I-66 inside the Beltway in the peak direction during rush hour, opened in December 1982 but was changed to HOV-3 within a year due to lack of use. It became HOV-2 (which it remains) in early 1995.

I can't think of any HOV-4 I've ever seen anywhere else.

When there have been issues regarding bridge closures, mass transit strikes, etc, some of the bridges/tunnels going into NYC have been temporary designated as HOV-4 during rush hours.

In terms of old signage, I don't appreciate it like others. Personally I find it old odd, and weird. I'm a Button-copy hater (don't kill me), yet I still hate Clearview. I like my nice FHWA refelective, standard, non IDOT-infected signs.  :colorful:

The only white-on-black signs I saw in abundance was in the St. Louis, MO area back in the late 80s.  I forgot what they were primarily used for, but there were enough of them to grab my attention of their existence.

The only other times I have seen white-on-black were the Virginia speed enforcement (VASCAR) signs at the borders and the occasional NIGHT SPEED LIMIT signs in Colorado.

In Texas--the only state I know of that still uses split day/night speed limits on a large scale--they are.  Split limits used to be much more common elsewhere in the US and a number of states, including Ohio and Washington state, used to have standard speed limit signs that combined both limits in the same message space (nonretroreflective white background, day speed limit in black, night speed limit in retroreflective lettering that was white except where it overlapped the day speed limit digits and so was retroreflective black).

probably.  given that the sign indeed says Superdome, then that must be it.  I don't remember who told me 1966.

1975 is very late for a black sign, but I know the city of LA was putting them up as late as 1977 so it's not unheard of.

That sign needs to put out of its misery -- it looks as though it was green and then they painted over it with black. And now, it's wearing off and thus looks terrible.

Also, the sign looks like an a la carte setup. The letters are split up into two or three and then the arrows are all alone as well.

What is up with that? How old is it?
Alps can tell us for sure, but it's on the Turnpike Extension (I-78), which I believe opened in 1956.

the night speed limit is still around in Texas?  I thought they got rid of that ~2012.  I know Florida has them on US-1 to protect the endangered key deer.  speed limit is 50 or 55 day (I forget), and 35 night.

QuoteSplit limits used to be much more common elsewhere in the US and a number of states, including Ohio and Washington state, used to have standard speed limit signs that combined both limits in the same message space (nonretroreflective white background, day speed limit in black, night speed limit in retroreflective lettering that was white except where it overlapped the day speed limit digits and so was retroreflective black).

Michael Summa referred to this style as "magic speed limit" signs, and the only photo evidence I have of the retroreflective style are from Florida.  I also have a photo of a cateyed 1940s example from Arizona.  SPEED LIMIT 60 in white text on black; cateyes, however, spell out 50.

Funny that!  I think the last time I drove in Texas was in 2005.  I know they got rid of the billboard-like statewide speed limit signs at stateline crossings sometime in the last five years, but I thought the night speed limits were still a going concern.

In regard to the "magic" split speed limit signs, I don't think I have ever seen a real-life example, but I'm quite sure I have a copy of the Ohio standard plan sheet for them.

I would have had a photo, had I knew of its existence.  I saw it in December, but sadly, I was riding in a taxi.   Had I known it was there, I would have had the camera ready for a picture.  Since I wasn't driving, doubling back wasn't an option either.  I saw it, and was like   "oh, sweet!"  But then it was gone from my view and no picture :(

So I found a black background sign in Seattle. SR-520(W) just after the merge from West Lake Sammamish Parkway:

As expected, it relates to a truck. More interesting, however, is that the sign is only 5 years old, according to GMSV.

That is a New Jersey Turnpike CLASSIC!!! (late 1950s? 1960s? Around there IIRC) These are some of the oldest guide signs on the Turnpike, especially with that gantry (I-beam?). NJTA recently took one of these down near Exit 6, and this one is probably gone too. But this sign looks like it's still in great shape, and I hope it's still there.

I believe the turnpike sign is still there.  This Bing street view (no GSV available for this location, surprisingly) shows it:
http://www.bing.com/maps/?v=2&cp=qshcr68ttvgc&lvl=19.29&dir=88.62&sty=x~lat~40.702609~lon~-74.068676~alt~-22.744~z~30~h~84.4~p~-2.3~pid~5082&app=5082&FORM=LMLTCC
It is located on the 14B entrance to the Newark Bay Extension (I-78) in Jersey City.  I go past here every two weeks or so - I'll look out for it next time...

I'm not sure how anti-Canadian you guys are (and this is the National Board), but I just had to mention:

All Canadian lane-guide signs have black backgrounds as opposed to the white ones here in the states. Because the original topic was about overhead signs, I went fishing for an overhead one in Montreal on Google Streetview:

(https://www.aaroads.com/forum/proxy.php?request=http%3A%2F%2Fi59.tinypic.com%2F2e5jyi1.jpg&hash=4d9e4fd0987259fba7148507b8d4fca45dae51aa)

I must say I like them: they stand out from the other white regulatory signs.
