PROVIDENCE, R.I. (AP) — A self-driving shuttle service has taken more than 25,000 trips during its first six months of operating in Rhode Island, according to the state Department of Transportation.

The Boston Globe reports Wednesday that transportation officials released data for the first six months of Providence's “Little Roady” one-year pilot program, with an average of 146 free shuttle trips daily in November. That's up from an average of 137 trips daily in October and 125 trips daily in June.

An agency spokesman said they're waiting to see data over a longer period of time before reaching any conclusions, but are pleased that people are using it.

It's the first service of its kind in the state. The free service operates daily on a roughly 5-mile route between Olneyville Square and Providence Station. There's no public transit along the full route.

Each vehicle holds six people, including an attendant who has the ability to take control at any time to ensure safety.
