I couldn't find anything about this in a quick search of Meto's site (though it was probably right in front of me), but WTOP.com had the following tidbit today:

If you walk or ride a bike to your Metro stop, the transit agency wants to hear from you.

Metro planners are in the midst of a study to evaluate demand from pedestrians and cyclists and access to stations for those who walk or ride bikes.

Metro says that between 2002 and 2007, the number of cyclists biking to rail stations during the morning rush hour increased 60 percent, to a daily total of more than 1,500. That number is expected to keep rising. The agency has identified $45 million in bicycle and pedestrian improvements it would like to implement before 2020. Likely upgrades include new bicycle cages and double-deck parking for bikes.

Metro will hold a workshop starting 5:30 p.m. Wednesday at its headquarters at 600 5th St., Northwest. Anyone interested in providing input is encouraged to attend.
