Since it's not likely I'll finish the conflation plugin any time soon, I'd just manually merge the nodes. If you check the MassDOT talk page I show how you can pretty quickly manually merge the nodes (123 by my count). Remember the second node you select will determine the location of the merged node. Also, you may want to remove the attribution/source tags of the OSM data, as they're all old MassGIS info anyways, that will speed up the merge process.<br>

By the way, the quality of the MBTA data seems of higher quality than the OSM data, at least spatially speaking.<br>

uploading is to make sure the tags are correct, no incorrect mappings, etc.

<div><br>By upload do you mean to the OSM database or to a file host for
other OSM contributors to download and merge? Hopefully it's the latter, so
that the OSM community can look at the data, the tags, etc and can help with
the process. We certainly don't want to just delete the existing 109 stops,
but rather update them with the new tags/position (if appropriate). While
somewhat tedious, merging 109 stops (with JOSM's merge command) won't take
too terribly long, and is a crucial step to take. If you don't wish to do
this step, then consider uploading the data for others to use.<br><br>I
started a conflation plugin for JOSM [0] intended exactly for this purpose,
for my county's bus data (~4000). The algorithm works quite well, but I got
stalled when designing the user interface for reconciling differences. I'd
like to finish it but like Ian said, I've been too busy in real life to
continue at the moment.<br><br>-Josh<br><br>[0]: <a href="http://wiki.openstreetmap.org/wiki/Conflation/Nodes" target="_blank">http://wiki.openstreetmap.org/wiki/Conflation/Nodes</a><br></div></div></blockquote></div>
