Methodology

Drive times were collected every 15 minutes during travel windows from the Google Routes API (Boston → Sagamore Bridge), with readings more than 3× the free-flow time excluded as outliers. Hours shown have at least one reading; peaks and calm windows require at least two. Averages are simple means of the readings in that hour on that day — this page reports one finished window, not a typical pattern. For typicals, see the full statistics page.
