James,
Thanks for the feedback. This is of course not good. I will make sure
we will be more careful with both the lane counts and the relations
not getting broken! I apologize. Did you fix the relations? If not I
will.

elaborate intersections Minh raised
After hands down. That's how I do intersections like that with one minor
difference. If the road on the right (as in the example) doesn't have a
divider, I merge the ways before leaving the intersection so I would have 3
traffic light nodes instead of 4.

Ryans Way and Sycamore Grove Ln. meet Fields Ertel Rd. at the same

People will map as they see fit and, as pointed out elsewhere in this thread,
it is not possible to correct all instances of all variations.
That said, the wiki is replete with guidance on preferred tagging for various

Hi Martijn: one thing wrong I do see at this particular intersection
are extraneous nodes with highway=crossing tags: two extra ones on the
(northerly) east-west ped-path and one extra one each of the (westerly and
easterly) north-south ped-paths.
To expand on the point of having both methods used, starting with the
multiple intersection points method, what if all four intersection
points were under a relation of a group of intersections, and the
number of lanes on each way was marked? That way, routing algorithms
could convert from the

I too prefer the after pattern since it is easier to do, especially when
you are making a road be dual-carriageway by using the parallel way
feature in Potlatch 2. Also, it matches the way it is on the ground better.
Since there seems to be unanimous agreement to map intersections this way,
then
