Lynx has won $3.5 million in federal grants to come up with the software and a plan to put the buses on the road by November 2013. The idea is to have the system running before the SunRail commuter train starts operations in 2014.

"You want it to be [working] pretty seamlessly before SunRail," Brock said.

FlexBus could help SunRail riders get to their final destination, as well as target "choice riders," or people who have access to cars but might be persuaded to ride a bus or train.
