I think I have a note somewhere that says "This is confusing in OSM. It's worse on the ground". I try to include those when I map something that seems completely illogical, but is an accurate representation of reality.
I fixed the Brunette/Bernatchey intersection - my imagery indicates that you can't get to that from the service lane, so you can't go from the middle of the H to westbound brunette and there's not enough room to do a u-turn. I also fixed up my UBC commute - unfortunately, the secondary/tertiary/primary designations don't mean as much in the city for travel time as the router thinks. It gets the work commute exactly right, in both directions. > -----Original Message----- > From: Adam Dunn [mailto:[email protected]] > Sent: Saturday, March 05, 2011 10:03 PM > To: talk-ca > Subject: Re: [Talk-ca] Secret routing demo. > > In Vancouver, from Hwy 1 heading west onto Brunette Ave heading > southwest, the routing software advises to take the offramp going north > onto Brunette, then do a u-turn at the Brunette/Bernatchey intersection > in order to head south on Brunette.
