<pre wrap="">Hallo,
op 1/1/2017 daalt de snelheid op Vlaamse gewestwegen van 90 naar 70.
Normaal gezien zullen we die wegen (zonder expliciete borden) dan
moeten taggen met
maxspeed=70
source:maxspeed=??:rural
maar wat komt er op de plaats van de vraagtekens ? Volgens [1] staat
daar de landcode, maar het geldt enkel voor Vlaanderen.
Ik zou tegen dan de BENELUX presets willen aanpassen.
---------------------------------------------------------
English:
On 1/1/2017 the maxspeeds on Flemish roads is lowered to 70. We should
map those roads (without signs) with
maxspeed=70
source:maxpseed=??:rural
Which "country" code should I use in the BENELUX plugin ? See [1] for
the syntax of maxspeed.</pre>
</blockquote>
I don't think that default values like maxspeed=*,
driving_side=*, or even oneway=no should be tagged on
highways.<br>
Most roads (in Belgium and in the world) don't contain
any, BTW, and it makes no sense using a few.<br>
A default values specification should be used instead.<br>
Those tags should be contained in the highest level
administrative boundary relation or equivalent in which
they apply.<br>
maxspeed=70 should apply to Flanders and maxspeed=90 to
Wallonia.</div>

what you propose is not working, because speed limits are
about roads, not administrative entities. You have to know the
context (rural/urban inside settlement according to traffic
law, etc.) in order to assign a maxspeed, and the only way we
currently use to understand which context applies are the
source:maxspeed values. It is very simple, doesn't require
preprocessing, can be applied by everyone without looking for
and downloading surrounding administrative polygons, and is
also quite reliable. Why would we give this up?<br>

Please don't remove important quotations.<br>
<br>
What you are saying is that every road in the world should have a
maxspeed=*. driving_side=*, etc.<br>
It's far from being the case. Hurry up to do so. Presently, GPSes
cannot deal with defaults.<br>
What I am saying is that there should be in the Walloon/Flemish
administrative boundaries relations or so a tag saying<br>
if zone is rural then maxspeed=90/70.<br>
That is what "def:<tt style="background:#EEF;white-space:nowrap"
dir="ltr"><a

title="Key:highway">highway</a>=<a
href="https://wiki.openstreetmap.org/wiki/Tag:highway%3Dprimary"

title="Maxspeed" class="mw-redirect">maxspeed</a> = rural" does in
<a
href="https://wiki.openstreetmap.org/wiki/Relations/Proposed/Defaults">Relations/Proposed/Defaults</a>.<br>
Instead of destroying propositions again please propose
improvements.<br>
I think that this proposition is sound but I don' agree with the too
complicated details of it.<br>
Yes, default speed limit rules are about administrative entities for
someone who understands what Flemish and Walloon mean.<br>
No, GPS dealing with administrative polygons is not complicated as
they keep saying on and on.<br>
It would even be simple with subareas but that's another subject.<br>
No tagging default maxspeed everywhere is not reliable because it
depends on many tags being correct instead of a few.<br>
As to using signals, that's the worst idea. They are valid up to
the next crossing, but not a private road, and they must be
repeated. Indicating which direction they apply to is tricky and a
source of error. The few signals I looked at were municipality
limits. They were redundant with boundaries (a disparaged feature)
and they did not mind indicating on which side of the signal was the
indicated municipality.<br>
Imagine that with speed limits and you get the picture.<br>
