Malcolm,

This looks like a nice dataset to add to the map. Pedestrian routing is
great. I like how you've accessed the smoothness of each section.

_JOSM Pro tip_
Install the UtilsPlugin2 plugin!
https://josm.openstreetmap.de/wiki/Help/Plugin/UtilsPlugin2
When you drop a bunch overlapping lines like this in JOSM, this makes it
easy to add nodes at intersections.
Run the validator to find all of the places where there are intersections.
There should be some at every intersection * 4. Select all of the errors in
the validator (which selects the overlapping lines en masse) and then press
"Shift-I". This will create a node connecting any overlapping lines exactly
where they overlap. Review for unintended overlaps! It might be good to do
it in small sections. After pressing "Shift-I", all of the new nodes are
selected as well, so you can add one of the point crossing tags. I don't
know what the consensus is on that tagging, but it is important that
sidewalks and roads intersect.

_A few comments_
- Make sure to drop that ArcGIS `Shape_Leng` field. No use for that in OSM.
:)
- Review the parts where the sidewalk is on a bridge, e.g. over Paint
Creek. Add the appropriate bridge tags there.
- If you have any data on ramps or tactile paving, that is useful for ADA
routing.
- There are few discontinuous sections of sidewalk (near Rawling and
Blackstone). To keep things routable, tie them in to the street grid with a
driveway.

Best,

Elliott
