Open Data Philly has a "Data Nomination" which allows people to vote on
what data should be released to the public and to 3rd party developers.
Top on the list is "Real-time positions of SEPTA buses and trolleys"...
OpenDataPhilly - Nominate Data
If this data was released into the public domain, web and mobile device
apps would increase, which would be great for riders.
Be sure to cast your vote!
