Implicit maxspeed

Communities Hrvatska (Croatia)
1

Zdravo everyone, I have recently crossed Croatia and I notice that there is no implicit maxspeed value, like there is for other countries.
I have started putting some maxspeed=HR:rural but it would be nice if there is a consensus about it, document it in the wiki, so that we can map it more widely and also “tell” the consumers what Croatian maxspeed values are.

May I remind that the implicit maxspeed values are used when there is no sign, and it’s very practical when a law changes, to just re-program the consumer, instead of re-tagging the whole country.

Thank you for your edits!

but it would be nice if there is a consensus about it, document it in the wiki, so that we can map it more widely and also “tell” the consumers what Croatian maxspeed values are.

The limits for Croatia (and law sources that define them) are already available in detail at Default speed limits - OpenStreetMap Wiki (which e.g. Legal Default Speed Limits calculator uses - which would be my go-to source if I wanted to know OSM country regulations)

I don’t know why Key:maxspeed - OpenStreetMap Wiki tries to duplicate some of that information instead of just referring to that main article which it links [1] :man_shrugging:

So feel free to copy information from that one wiki page to another (I personally am too afraid to break that complex wiki table :slight_smile: ).

  1. coming from database world, I found the idea of such manual copy/pasting of data and breaking the Normal Forms horrendous source of problems which should be avoided at all costs. You’ve just stumbled upon one of them :sweat_smile: ↩︎

It’s not duplicating, but to substituting, in case there is no maxspeed sign.

maxspeed laws don’t change often, but when they do, it’s very hard to fix all the tags.
Knowing the difference between an explicit maxspeed=90 (with a sign) and an implicit maxspeed=HR:rural (without a sign) will make such a change very easy and with correct results.

In France there is still wrong maxspeed=90 where the correct is maxspeed=FR:rural although the law has changed several years ago that the rural maxspeed is 80.

Perhaps there is misunderstanding; I did not mean “duplication between maxspeed and maxspeed:type tags” (which encode - as you note - different information), but instead “duplication of country-specific implicit maxspeed values between following two wiki pages:”

In other words, former wiki page contains more detailed data (including all Implicit maxspeed data for Croatia for HR:urban, HR:rural etc.), while the latter wiki page doesn’t.

Or does that first wiki page misses some of the information which you are looking for? (and if so, what exactly?)

I agree! And many editors (e.g. StreetComplete) thus prefer tagging only maxspeed:type=HR:rural (without any maxspeed tag) in such cases, as it avoids not only the need for such periodic checks, but a whole slew of other problems.

In other words, tagging maxspeed:type= HR:rural / HR:urban instead of current-state-of-the-law-generic-maxspeed=90 is a great idea!

Note however that (in Croatia at least, but also elsewhere, including France) it is much more common to tag maxspeed:type=HR:urban instead of maxspeed=HR:urban.

also, somewhat related... [click to expand]

According to that first wiki, situation is much more complex even for maxspeed:type=FR:rural - depending on exact road type, weather conditions, and type of the vehicle you’re driving, actual maxspeed may be 130, 110, 100, 90, 80 or 60. – so using maxspeed:type=FR:rural is much preferred than just setting maxspeed=80!
