Steering axle?

ODOT OR12-5d

Some bridges in Oregon are posted with signs that make a distinction between steering axles and other axles. I thought about using maxaxleload=10000 lbs maxaxleload:conditional=12000 lbs @ (steering), but this seems problematic because normally the "vehicle property" conditions used in conditional restrictions apply to the whole vehicle, not an individual axle. – Minh Nguyễn ^💬 18:52, 4 July 2019 (UTC)

Need for Examples?

Is there really a need for all the examples? I think OSM should assume its contributors have a reasonable amount of intelligence to know about roads signs. It just clutters. --DaveF63 (talk) 14:18, 3 February 2020 (UTC)

This has nothing to do with intelligence, but with detailed knowledge of this topic or the lack thereof. People out and about on the road surveying for OpenStreetMap cannot be expected to be experts in this field to know exactly which weight limit to apply when they see a sign. Gross vehicle weight rating (GVWR), gross vehicle mass (GVM) / gross weight, actual weight, actual load, max load, axle weight/load, bogie a.k.a tandem axle weight/load etc. can easily be mixed up. I think it can't hurt to give rather more than less examples on this topic --Westnordost (talk) 15:04, 3 February 2020 (UTC)

People out and about on the road surveying for OpenStreetMap cannot be expected to be experts in this field to know exactly which weight limit to apply when they see a sign. < Yes they can. Motorists have to pass tests proving they're competent enough to gain a licence enabling them to legally drive. This includes comprehending road signs! --DaveF63 (talk) 21:45, 3 February 2020 (UTC)

Not every contributor to OpenStreetMap has a drivers license (in the country he is contributing), much less for trucks. There are also max speed signs for train drivers. It wouldn't make sense to remove the documentation how to tag these because train drivers are required to know how to read these signs. Anyway, you concerned about that it clutters. Well, maybe the examples can be arranged in a better way, like suggested by Kovposch (you deleted his comment accidentally), but to me it looks quite clear how it is now --Westnordost (talk) 01:23, 4 February 2020 (UTC)

Lets assume that all people have driving license, were tested in knowledge of weird max weight signs, and still remember this knowledge. It does not mean that they all know which OSM tags apply to given signs. And note that for most people that drive car not a truck - may generally ignore all max weight signs as cars are generally not restricted by them. And especially signs such as "max axle load" are not going to apply to cars and are probably out of scope for car driving license test Mateusz Konieczny (talk) 14:15, 4 February 2020 (UTC)

Concerning "clutter", I would agree the section could formatted/styled better. Right now it's not very elegant (like all other restrictions). Or maybe you want to move some non-specific/illustrative ones off to a new sub-page, or Wikipedia? Kovposch (talk) 15:57, 3 February 2020 (UTC)

In Wikipedia it would be out of scope - OSM tagging is not so important. I am not sure is it useful to move it to a separate page, there is no other content that is blocked/hidden by this Mateusz Konieczny (talk) 14:17, 4 February 2020 (UTC)

Sorry, I meant perhaps add the full list of straightforward national signs elsewhere (I see wiki pages linking to Wikipedia's article a lot too), if we choose not to re-style or re-format it (not sure how much it can be improved by a table or other forms); and only add signs that would be illustraive examples of the tag here. Right now it may not be very helpful to everyone to see a bunch of maxaxleload=* under simple "*" signs "around the world". If more examples are added in the future, this will put the more confusing (thus important) complicated examples in the US underneath (I'm not from the US either). Like, this will also diminish Canada's "Class B road" (worthy to explain) or Ukraine's "5TC" (potentially confusing unit) sign in the middle. Kovposch (talk) 19:04, 4 February 2020 (UTC)

Axle load (bogie)

There is no show how to indicate the load in the case of a different number of axles.

Example (RU): http://gkhb.cap.ru/Content/photo/201802/19/Albom264712/slajd3.jpg

Translation:

• maximum weight 5t
• maximum axle load 4t
• maximum axle load for a two-axle bogie 3t
• maximum axle load for a three-axle bogie 2t

There is a suggestion to write:

• maxweight=5
• maxaxleload=4
• maxaxleload:2=3
• maxaxleload:3=2

But maybe it's Key:maxbogieweight? - Corsa5 (talk) 06:37, 28 August 2021 (UTC)

• maxweight=5
• maxaxleload=4
• maxbogieweight=6? (2x3=3x2=6)

Technically you can use maxaxleload:conditional=3 @ (axles=2); 2 @ (axles=3), but I don't know if this is preferred.

---- Kovposch (talk) 18:39, 27 August 2021 (UTC)

sure 6 is definitely the wrong decision - Corsa5 (talk) 06:37, 28 August 2021 (UTC)

The signage seems to working around the absence of bogie weight sign in Russia in a verbose manner. ---- Kovposch (talk) 07:02, 28 August 2021 (UTC)

I think this still refers to the weight of the cart. I moved the question to that topic Corsa5 (talk) 09:02, 28 August 2021 (UTC)
