A Transit Authority is a government agency responsible for overseeing public transportation systems within a specific area, such as a city or region. Their main duties include planning, operating, and maintaining various modes of transport, including buses, subways, and light rail. They aim to provide safe, efficient, and accessible transit options for residents and visitors. Transit authorities also manage fare collection, service schedules, and infrastructure development. They often collaborate with local governments and community organizations to improve transportation services and address the needs of the population. Examples of transit authorities include the Metropolitan Transportation Authority (MTA) in New York and the Chicago Transit Authority (CTA).
