Transit Screen is quite simple, really: it’s exactly as it sounds. Transit Screen displays information relating to the forms of local public transit. Train times, bus times, distances to popular locations and how long it will take to get to them by not only public transit but also by foot and bike.
Transit Screen seeks to help commuters make smart choices about how they transverse the city they are in, and make that information more readily available. So far, it’s availible in the Greater Washington DC Area, the San Francisco Bay Area, Atlanta, Boston, Chicago, Detroit, Honolulu, Los Angeles, Minneapolis, New York City, Portland, Seattle, Tampa Bay, Toronto and Vancouver. As far as how they make money, it’s simply SaaS.
