It's simple on a motorway. But, for a simple example on a surface
road, how
do you know where the straight lanes go if there are 3 lanes after an
intersection but 2 before?
Depends on what data you have. If you have lane width information,
then it's easy to figure this out. If you don't, then you can't
figure this out.
Nevermind. Yes you can. If the center of the 3 lane road is to the
left of the center of the 2 lane road, then the lane was added on the
left. If the center of the 3 lane road is to the right of the center
of the 2 lane road, then the lane was added on the right.
Ways are not mapped this way. And even if they were, this would only
work if there's a median.
Not to mention that the line between the lanes doesn't always go
straight through the intersection.
