From the Contra Costa Times:
In 2013, BART abandoned rules banning bicycles from BART cars during busy commute hours after several pilot test periods.
A survey of 2,300 riders presented at today’s Board of Directors meeting found there were 3,800 more weekday BART trips with bicycles from 2012 to 2014, an increase of more than 20 percent.
