The Rhode Island Public Transit Authority is offering a new on-demand transit pilot program in Washington County.

The pilot, called Flex On Demand, brings the convenience of rideshare apps like Uber and Lyft to public transportation, allowing passengers to book a trip from wherever they are within the service area, according to RIPTA.

RIPTA is launching Flex On Demand in Narragansett, South Kingstown, and Kingston. The pilot service is available Monday through Friday from 7:50 a.m.-5 p.m. and on weekends and holidays from 10 a.m.-5 p.m. The cost for a one-way trip is $2, the same as RIPTA’s fixed-route bus service. All flex vans are equipped with wheelchair-accessible features to accommodate passengers with limited mobility.

Passengers can request a ride using a smartphone app, which will provide an estimated pick-up time, track the ride in real time, and send an alert upon arrival. This service is fully ADA-accessible, offers curb-to-curb transportation, and — unlike many rideshare services — has no surge pricing.

“At RIPTA, we are always seeking innovative ways to connect our riders to where they need to go, and Flex On Demand is a prime example of that commitment,” said Christopher Durand, RIPTA’s interim chief executive officer. “This new pilot program leverages the convenience of modern technology to make public transit more accessible, flexible, and responsive to the needs of our communities.”

RIPTA is offering the first Flex On Demand ride free with promo code “203Free.” Riders can redeem the promo code within the Flex On Demand app after signing up for an account. The code is valid until Sept. 30.

The ride-share service is only available in RIPTA’s 203 Flex Zone. The app is available for download from both the Apple iOS App Store and Google Play Store. Passengers who do not have a smartphone can call a Flex reservationist on weekdays from 8:30 a.m.-4:30 p.m. at 401-784-9500, ext. 1220, to book their ride.
