#mutcd — Public Fediverse posts

Just sent a note to NYC DOT Commissioner. DOT-646556-R7W This HHP / Route 9A Northbound Exit 12 exit ramp is two lanes wide. Why does a road posted at 50mph require an exit ramp that is two lanes wide? One can only make the turn onto the exit ramp from one lane so we have a case of parts of one lane expanding to two lanes. Seems very wasteful.

#RoadWaste
#ExitRamp
Neglected to ask if this ramp is #MUTCD compliant. Will find out myself. If unsatisfactory answer this becomes FOIA request.

I'm very disappointed that the new #MUTCD is only available as a PDF: https://mutcd.fhwa.dot.gov/kno_11th_Edition.htm

Sure, the PDF might be compatible with a screen reader, but you know what it's not compatible with:

- hyperlinking to specific sections
- narrow screens, such as phones

Mainstream media outlets covering boring things like revisions to the Manual on Uniform Traffic Control Devices for Streets and Highways? Yes please. This is a matter of literal life and death, and went ignored for way too long.

New #MUTCD mostly fixes problems I found in definition of "intersection." But it opens new cans of worms by defining "site roadway" to include any road on a university site, with "site" undefined. What, eg, are the boundaries of the site of Harvard?
Any road maintained by a public agency (including a public university?) is also a "public road." Junctions of site roadways & public roads w/o signals or stop signs are not intersections, so pedestrians don't have right of way to cross.

Via StreetsblogUSA, here are some early reactions to the new edition of the #MUTCD , the federal manual that standardizes designs for signs and traffic signals on America's notoriously deadly roadways:

The 11th version of the MUTCD is live!

Santa did not bring me my #MUTCD present (a much clearer Pedestrian Hybrid Beacon sign, like the kind they have in faraway lands like Fremont) 😭

New #MUTCD tomorrow! https://www.federalregister.gov/public-inspection/2023-27178/national-standards-for-traffic-control-devices-the-manual-on-uniform-traffic-control-devices-for

I'm not going to have time to read it before then, but I look forward to someone publishing a breakdown of all the changes.

The new #MUTCD has a trailer on YouTube, but the release date is "soon" https://www.youtube.com/watch?v=IdOO3xcPU7I

This highly entertaining sign montage is for all you transportation and especially MUTCD fans out there: https://www.swiss-miss.com/2023/11/signs-2.html.

The eleventh edition of the #MUTCD is expected to be published this year! That's great news for traffic safety, and only the better part of a year late! https://mutcd.fhwa.dot.gov/mutcd_news.htm

While it's not the new #MUTCD, @Streetsblog has coverage of the new #PROWAG guidelines for urban design: https://usa.streetsblog.org/2023/09/06/american-streets-may-soon-get-their-first-accessible-design-standards-from-the-feds

RT @schlthss: The #MUTCD signal warrant system - made up by a bunch of dudes in a room in the 1930s- is not an appropriate decision making tool in a #SafeSystem people first world.

RT @[email protected] The most commonly applied traffic engineering methodology says you should not put a pedestrian signal here unless there are already at least 20 pedestrians crossing. But people are never going to cross here unless there’s a signal. It’s like a traffic engineering zen koan

@jcriecke
Dunno!
The proposed changes for the 11th edition of the #MUTCD included a whole lot of thigns: https://www.federalregister.gov/documents/2020/12/14/2020-26789/national-standards-for-traffic-control-devices-the-manual-on-uniform-traffic-control-devices-for

But they also received 17k+ comments on that proposal, and probably made revisions in response to those comments, so no one is sure what they'll do.

A wishlist for the new #MUTCD, via @Streetsblog and #nacto https://usa.streetsblog.org/2023/08/16/six-changes-to-look-out-for-in-the-next-edition-of-the-mutcd

I've always felt that the alternating red flash, which is also used for railroad crossings, should be not be used for "stop then proceed" because at railroad crossings it's an absolute stop, you do not proceed. The #MUTCD even warns against using alternating red flash for exactly this reason. I think there needs to be a better visual distinction between railroad crossings and "stop then proceed" traffic lights, especially at night.

@sdwilsh A few years ago I saw a sign at a construction project in Seattle that read "Traffic merge with bikes." While I would consider myself to BE traffic when I ride, had to love the swap of modes in the wording for who should yield. #BikeTooter #MUTCD #transportation #WeAreTraffic

The new #MUTCD is late: https://usa.streetsblog.org/2023/07/03/the-mutcd-update-is-late-and-while-we-wait-people-are-dying

The rumor mill says that they received a lot of feedback from safe streets people, and I hope they're making revisions to suit. But I'm worried it'll arrive too late for #Columbus' Bikeways and Micromobility Plan Update later this summer.

The revised 11th edition #MUTCD was due today; it's now delayed. Any guesses on when #FHWA will release it? https://mutcd.fhwa.dot.gov/index.htm

Vignesh is a great follow

Today, from the "doesn't really matter because they're never used" department...

I think that U.S. #Metric speed limit #Signs should have a red ring around the number, even though the Manual on Uniform Traffic Control Devices says that the ring should be black.

It's still a #Regulatory sign with the red ring, and it would stand out a lot more.
