In the United States, public bus schedules are available through the website and offices of a city's public transit authority. Usually, buses and bus stops also have posted public transportation schedules for the convenience of their guests.
In New York, home of one of the largest public transportation systems in the United States, bus schedules for each borough are easily to locate through the Metro Transit Authority's website, web.mta.info. Cities with public transportation tend to make schedules accessible online, but most offer physical copies as well. Transit authorities usually have central offices where schedules, maps, closings and other information regarding the day-to-day operation of public transportation is available.
