Public transportation systems are networks designed to move people efficiently within urban and rural areas. These systems typically include buses, trains, subways, and trams, providing affordable and accessible travel options for residents and visitors. They help reduce traffic congestion and lower environmental impact by encouraging shared rides. In many cities, public transportation is managed by local or regional authorities, ensuring that services meet the needs of the community. Systems like Metro in large cities or light rail in smaller towns offer scheduled routes and stops, making it easier for individuals to commute to work, school, or leisure activities.
