Analysis of the Boston Dudley-Downtown Silver Line Bus Rapid Transit

Using the BRT Scorecard put together by the Institute for Transportation and Development Policy, I analyzed the Silver Line bus rapid transit line between Dudley, in Boston’s Roxbury neighborhood and downtown.  There is another Silver Line in Boston that connects South Station with the airport and selected South Boston locations, but the two segments are not connected (that’s a whole other issue).


Bottom line:  17 points out of 100.  Hardly qualifies as a bus rapid transit at all.



Here are my detailed findings.
