<pre wrap="">Hallo,
I was contacted by a mapper from Germany with whom I worked on turn:lanes.
He has to following question, can someone with local knowledge inform
us about the road classifications ? I have the impression a lot of
streets are indeed residential. Feel free to reply in French, I'll
translate it to English for him.</pre>

Hi,<br>
<br>
The overpass map doesn't show Liège but the North of it.<br>
When run, I can't make sense of what I see.<br>
Could you get rid of the nodes?<br>
<br>
In Liège, most of the ways are residential, of course.<br>
You can see not yet mapped buildings by displaying the BE PICC
layer.<br>
But, beside surrounding and access motorways, some ways are suitable
for slower, through traffic.<br>
Those are brown on OSM.org and mainly: alongside Meuse and
Dérivation, rue de l'Yser to Ans, N3, N61, N30, N63, N90. (...?)<br>
Notably missing the brown status is N671 for carrying the heavy
traffic in direction Namur.<br>
(The rule is that brown, main National, primary roads are 1 or 2
digits, but 671 certainly deserves that).<br>
Beside that, there are yellow, secondary wider streets bordered by
buildings like Boulevard de la Sauvenière that can be used for
faster moving inside town but isn't recommended for traveling
through.<br>
<br>
I'm not mapping Liège and I don't know every small streets of it
everywhere, but I can comment specifics like N671 if no one else
stands up in this thread.<br>
<br>
Cheers
<br>

Now I want ask you about another problem.
Coming from here
<a class="moz-txt-link-freetext" href="http://forum.mapfactor.com/discussion/comment/13515#Comment_13515">http://forum.mapfactor.com/discussion/comment/13515#Comment_13515</a>
I checked Liege to find out the mapping of roads there:
<a class="moz-txt-link-freetext" href="http://overpass-turbo.eu/s/imn">http://overpass-turbo.eu/s/imn</a>
My guess is, that unclassified is used wrong there and that is the
reason for strange routings. My opinion is that unclassified as the
lowest kind of connecting roads do not end at city borders and have or
need common connection to same or higher class inside of towns or
villages. For me routers should avoid residentials and lower as much
as possible. Do you have any idea to check and correct this in Liege
to make routing better?
If there are any questions, please ask.
Regards
Michael aka hurdygurdyman
