The Gwinnett County Board of Commissioners Tuesday established a citizen committee to advise the county as it studies transit alternatives in the I-85 corridor.

Gwinnett is studying light rail, commuter rail, bus rapid transit and other ways to get commuters off I-85 at rush hour. Ultimately, it will determine which method works best and perform more detailed engineering and environmental reviews.

The citizens committee will provide feedback to county employees and consultants before the study is considered by commissioners.
