There would be some absolute limitations we will have to work around, but while it would make these things easier to do I don't think that should be the real reason we put lanes information into it's own table separate to ways. > We needs some way to map thinks like the pavement having 3 steps in it > where the road is flat, and this is likly to be difficult to push > chairs and wheel chairs and hence they need to cross the road to avoid > the steps.....

Dual carriage ways are physically separated, regardless if that's a strip of grass or by barriers so I don't see that as an issue in the same context as being able to tag lanes individually. _______________________________________________ talk mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk
