<div>Okay, I understand. (I suppose that “truck limitations”

<div class="gmail_extra">One more question which is a little bit
specific to Ivory Coast: Here, most roads are very bad. While
in residential zones, maxspeed=60 is correct because this is
the traffic roule, in reality you often can’t go faster than 5
or 10 km/h because the ground is so bad. Is there any tagging
(beyond maxspeed) that reflects this?<br>
</div>
</div>

<br>
Yes, use track=grade1 (greater grade is currently even completely
excluded for car) or a bad surface like ground, grass, dirt, ...<br>
<br>
(or a different highway type)<br>

<div class="gmail_extra">It’s just that I was
wondering which of these tags is worth to do
all the work to add it to OSM when I map
streets – and which isn’t so important
because it doesn’t influence the routing.<br>

Ah, ok I see. So let me reformulate my answer a bit to
make it more clear for other mappers as well.<br>
<br>
I think the most important thing is to add addresses
especially in countries != Germany! Of course this has
nothing to do with routing but we really need address
search like pelias or photon/nominatim for routing.<br>
<br>
Besides addresses, I think indeed turn restrictions and
truck limitations are the information which often
absent. (But both of them are currently not taken into
account from GH but will be this year probably.)
Maxspeed is another candidate and last but not least
there are many problems with oneways. I think they
cannot be blind alleys but often they are. See the last
discussion about 'not found' or this here:<br>

<br>
I can easily create a script for this issue to find out
all nodes and ways with this problems world wide, if
there is interest.<br>
