Do we have a relation for storing the information that the left lane
continues on [way
394112487](https://www.openstreetmap.org/way/394112487) and the right
lane on [way 290130794](https://www.openstreetmap.org/way/290130794)?
This information is important in order that routers don't announce too
late (i.e. when the lanes can't be changed anymore) which lane one has
to take.
We do have a (recently approved) relation type for this: 'connectivity':
https://wiki.openstreetmap.org/wiki/Relation:connectivity
Or is turn:lanes + change:lanes enough? (And what if there were no turn
lane markings?)
In this case with a simple 2-lane way splitting into 2 1-lane ways I
would not use this relation - it should be obvious to all routing tools
how these ways relate to each other. The example looks more complicated
than it actually is, because some ways are oneways and some are not. For
routing purposes, the lanes in each direction can be treated separately
from each other.
