BART Director Debora Allen has said she would like the transit agency to consider banning panhandling on trains and in stations.
Complaints from riders spurred Allen to take up the cause, which she will bring up for discussion at a BART board meeting this week, she said to TV-station KPIX.
No one would be allowed to ask for money, under Allen's idea, including musicians, performers and mothers who carry infants in slings.
There are no details yet on how the anti-panhandling rule would be enforced.
Critics say such a broad rule would violate the First Amendment.
BART currently bars what it calls "aggressive panhandling" and loud music.
