One of the key advantages of metro systems is their ability to reduce traffic congestion and pollution. By offering a fast and affordable alternative to personal vehicles, metro trains help decrease the number of cars on the road and contribute to a more sustainable urban environment. They also play a critical role in supporting economic growth by connecting people to jobs, schools, markets, and other vital services.

Metro networks usually operate on a fixed schedule, with trains arriving every few minutes during peak hours. Stations are strategically placed throughout the city to provide easy access, often linked with other modes of transport such as buses, trams, and regional rail services.
