Public transportation networks consist of systems that provide shared transport services to the public, including buses, trains, subways, and trams. These networks are designed to facilitate the movement of people within urban and rural areas, helping to reduce traffic congestion and lower environmental impact. These networks are often managed by government agencies or private companies and are essential for connecting communities. They offer affordable travel options, improve accessibility for individuals without personal vehicles, and contribute to economic growth by linking workers to jobs and services.
