[talk-au] FW: Am I doing intersections right?

[Michael]

Sorry,

Though not all of those slip lanes is the same, the broken one has through_route which is not a valid tag. (Category rejected)

Several other relations there also have that tag, however they are all named ways.

Perhaps that is the cause?

Please don't break my placement tags. (I've restored them.) They were there on purpose, and they are not what causes OSRM to generate that "Turn left onto unnamed road" instruction. 

Also, please don't delete my transit relations, these things take a lot of work to properly setup without explicit editor support.

In case you are wondering what these tags are for, they are part of detailed lane tagging as you can see here:

https://www.dropbox.com/s/ednlniwp6bcl5wk/1521024394681.jpg?dl=0

The placement=transition tag is necessary to indicate that this particular segment is not actually where it is in the real world, but is necessary because of the discrepancy between mapping roads as lines and roads having a width an multiple lanes in the real world.

The transit relation is necessary to define which of the lanes from one way segment connect to which of the lanes in the next way segment. In this case it indicates that the leftmost turn lane flows straight into that slip road.


The other 3 slip roads at this intersection have the same tags, and they do not result in OSRM producing such a driving instruction. If there were any obvious tagging mistakes, I would have fixed them already.


Cheers,
Thorsten
