Metro Accessibility Advisory Committee is looking for riders with disabilities and senior citizens interested in joining the group.

The panel has 20 members, all volunteers, who advise Metro on how to improve the commuting experience for people with disabilities and senior citizens.

In recent months, the committee prepared a report that highlights lighting problems in Metrorail stations and recommends better lighting on platforms, in the walls along tracks, and around the elevators, escalators and kiosks. The group last year was instrumental in getting the transit agency to make new SmarTrip vending machines fully accessible before deploying them to the Metro stations.

Interested candidates must ride Metrobus, Metrorail and/or MetroAccess, the transit alternative for the elderly and disabled. Positions are available for residents of the District of Columbia, Prince George’s, Montgomery, Arlington, Fairfax, Fairfax City, Falls Church and Alexandria.

Applications can be found online. Or you can call Metro’s Department of Access Services at 202-962-1100 to request an application form. Applications can be submitted online, mailed to the Accessibility Advisory Committee at 600 Fifth St. NW, Room 7A-01, Washington, DC 20001, or faxed to 202-962-1274. The deadline to apply is 5 p.m. on March 24, 2013.
