Nicole Tedesco from TCAT, a transit agency in the Ithaca, NY area, posted this informative discussion of the challenges that some agencies face in making their schedule data available to the public. She ends with this request for better tools for small agencies:

So, this is my challenge to Google and to all of you transit buffs out
there: build us a very cheap or free database or other software that
will maintain schedule data and export to GTFS. There are products
out there on the market, but they cost an arm, a leg, and your
firstborn. There is huge market potential for someone to build an
excellent product, sneak into the market, and grab up all of the
smaller customers that wouldn’t touch one of the big companies (and
vice versa).
