The MBTA has published a document titled MBTA ScoreCard.  Acting General Manager William Mitchell writes on the first page:

With this ScoreCard we begin publishing the same performance metrics that we use internally to measure our progress towards meeting our service quality goals.

It’s 25 pages of mostly graphs, covering statistics on ridership, on-time performance, speed restrictions, dropped trips, maintenance, and safety.  Some of the data are woefully uninteresting.  Some are fascinating.

It’s not clear how often we’ll see updated ScoreCards.  The current document is dated “September 2009,” implying a monthly publication, but some of the graphs cover data dating as far back as January, 2004.  Even if this is the only ScoreCard we see, it’s a nice gesture.  Score one for Mr. Mitchell.
