I don't live there but Mapillary user marc has nice coverage for some of the roads in question[1]. I am _guessing_ that a formula was developed based on the width value that Massgis had in their data. Looking at Mapillary while in JOSM, it almost looks like there is a one off error or a condition in one area of Massachusetts did not apply to another area of Massachusetts. Again these are just guesses! If you look at Massachusetts Avenue via JOSM/Mapillary, the street looks like lanes = 2 except for a turning lane here and there.
Massachusetts Avenue width = 18.9; lanes = 3 https://www.openstreetmap.org/way/8615119 Hancock Street width = 12.2; lanes = 2 https://www.openstreetmap.org/way/8615674 width = 7.6; lanes = 1 https://www.openstreetmap.org/way/8614912 [1] https://www.mapillary.com/app/user/marc?lat=42.382047952522356&lng=-71.18021987120689&z=12.90517848549394&focus=map&pKey=L9nOys_VqYuhOjcZ0Z9I9A On Fri, Sep 23, 2016 at 11:27 AM, Spencer Gardner <spencergard...@gmail.com> wrote: > Is anyone on here familiar with the process that was used to upload > MassGIS road data for the state of Massachusetts?
