Correction: A previous headline incorrectly said the map was released by the MBTA. The map was created by Peter Dunn and is unofficial.
If you've ever thought about moving to get a better commute, a new map of the MBTA's subway system might help you.
For instance, a Davis Square resident trying to get to South Station can expect about a 17-minute trip, according to the map. A person who gets on at Sullivan Square Station can be in Downtown Crossing in seven minutes, the map says.
Here's some of what jumped out at Dunn when he studied his map:
Seeing all schedules in a single map shows that not all Green Line branches are created equal. It takes just as long to get from downtown to Boston College on the B line as it does to get to Riverside on the D line, despite being about half the distance. And even though they’re just a few blocks apart, Chestnut Hill Ave (B line), Cleveland Circle (C line) and Reservoir (D line) are 27, 20, and 14 minutes from Kenmore, respectively.
As Dunn makes clear, the times used are averages — and official ones at that. In practice, trains get delayed, cars go out of service, and trains fill up.
