Flex is an on-demand microtransit service operated by Via Transportation, intended as a last-mile service to connect fixed route riders to their final destinations. The service operates similar to ridesharing; a passenger books a ride via telephone or through the Flex smartphone app, and a marked vehicle (usually a minivan) picks them up (within 30 minutes) and takes them to their destination. Flex was launched in March 2021, and currently operates in five service zones, covering all or part of 20 SMART member communities.
