I know there's a few folks at TriMet working on geometry and access issues, however I do have a couple friendly requests:
Don't squash "name=" without double-checking it first. Most glaring example: The Robert Baldock Freeway is not "I5 Freeway (North|South)bound." Nor is the Boone Bridge.
Don't squash "highway=" without looking. At least make an honest attempt at figuring out why something is tagged the way it is before arbitrarily changing paths to footways, cycleways to paths, etc, especially if they're already part of an lcn relation.
Don't squash "cycleway=*" without looking or ground knowledge. I've noticed several instances of opposite_lane being cleared or set lane when the lane is only on one side.
