Public transit refers to a system of shared transportation services that are available for use by the general public. This includes buses, trains, subways, and trams, which operate on scheduled routes and can accommodate many passengers at once. Public transit is designed to provide an affordable and efficient way for people to travel within cities and between regions. Using public transit can help reduce traffic congestion and lower environmental impact by decreasing the number of individual cars on the road. Many cities invest in public transit systems to improve accessibility and promote sustainable urban development, making it easier for residents to reach their destinations without relying solely on private vehicles.
