Where Somerville moves

New to Somerville? You're joining a town that moves — neighbors logged 5,484 trips on foot, by bike, and on transit in the last 90 days, and Massachusetts Avenue, Cambridge Street and Monsignor O'Brien Highway are where you'll find them. A corridor appears only once three or more different people have traveled it — and it follows Somerville residents wherever they go, including into neighboring towns, within about six miles of the town center.

Shift automatically counts your walks, rides, and transit trips — every trip adds to Somerville's totals on this page, earns you rewards at local businesses, and enters you into seasonal prize drawings.
