Ridership on Gainesville’s public transit system isn’t near Red Rabbit levels, but officials are optimistic about the fixed-route bus service’s future numbers. More than one year after Gainesville Connection buses started rolling and the Red Rabbit was retired, the number of riders is expected to hit 175,000 this year. That’s a far cry from the 208,654 in 2012 reached by Red Rabbit, which had operated since January 2000.
