Cool !, 

I'll not being asked anymore by my GPS to make a U-turn ASAP when I get in
an uncorrected motorway link, or worst.

Being asked to drive for more than 100 Km on secondary roads, up to the next
adequate link !

Thanks again.

I am happy to report that all of Canada should now be free of this issue! I
just fixed the last one all the way west in Saint John's. Yay!

Some updates on this issue:

 

I contacted Martijn a while ago with the suggestion of running this as a
Maproulette. He liked the idea but I haven't heard back in a while. He also
asked me how many cases we're talking about and based on the Overpass query
mentioned upthread I came to the conclusion that the number is actually not
that high (maybe 400 cases in all of Canada at the most). Therefore I've
started fixing the issue manually and already cleaned up all of Quebec. It
took me several hours, but that's partly because you always discover other
issues to take care of as you go along (e.g. missing motorway_junction, name
vs. exit_to on those junctions etc.). 

 

I'll continue working on this in Ontario now and I encourage others to go
ahead in the other provinces, too. Just run http://overpass-turbo.eu/s/1CI
on the appropriate bounding box and then go through each of the spots that
come up. If there is hi-res Bing imagery available the fix will be obvious;
and if not common sense should still tell you if a segment is oneway=yes or
oneway=no. I have added a oneway tag to every motorway_link segment, both to
avoid any misunderstanding with the default and to allow me to track the
progress on the Overpass map.

 

Cheers,

 Harald.

So before contacting Martijn I want to be sure that we can properly identify
the potentially problematic ways. What we are looking for are ways that
match the following query:

 

(highway="motorway_link") AND (NOT oneway=*) AND (lanes!="1") 

 

Or in natural language: ways that are motorway links but don't have the
oneway tag nor are tagged as having one lane. If you want to test this
query, go to this link http://overpass-turbo.eu/s/1CI and adjust the
bounding box coordinates for the desired area.

 

Comments?

The example I provided yesterday was not fixed.  Most the exits having a
similar look along the trans-Canada Highway in Quebec are the same. I have
also found examples in Alberta and In BC.

I can write an email to Martijn with a proposal. Does anyone have a link to
an exit that has not been fixed yet to use as an example?

It seems to me it is the only safe solution. I go for maproulette.org

+1 for the Maproulette.org solution.

Hooo, I see, and I also see there was not a large consensus on that point
(Discussion) since all other ways are having a different behavior.

 

About all motorway_link in Canada are having the same problem!

I don't know, I rarely encounter this issue in practice. Adding oneway=no to
all motorway_link seems rather dangerous and counterproductive. The best
solution would probably be to create a query that will find all imported
motorway_link that have not been touched since the import and then check
them. Depending on how big the task is we could ask Martijn to set it up as
a Maproulette (http://maproulette.org/). Or we set up a wiki page to
coordinate people going through all the motorways/exits and make sure
everything is okay by hand. There are only 33 Autoroutes in Quebec after all
:-)
