A reverse commute is a round trip, regularly taken, from an urban area to a suburban one in the morning, and returning in the evening.
However, track capacity on some railroads (for example, the Long Island Rail Road in the suburbs of New York City) significantly reduces or even eliminates reverse commute options.
For example, Metro-North Railroad runs rush hour New Haven Line trains from New York City to Stamford, Connecticut, and the surrounding suburbs to accommodate its many reverse commuters.
Low unemployment rates in the suburbs may help to fuel the increase over the past years in reverse commuter ridership.
As such, there are many people who live in Washington and work in Maryland and Virginia, either driving, taking Metrobus, Metrorail, or carpooling.
