Public transport refers to systems of transportation that are available for use by the general public. This includes buses, trains, trams, and subways, which help people travel within cities and between different areas. Public transport is often more affordable than using a private car and can reduce traffic congestion and pollution. Many cities have developed extensive public transport networks to make commuting easier for residents. By using buses and trains, people can save money and time while also contributing to a cleaner environment. Additionally, public transport can promote social interaction, as it brings together individuals from various backgrounds.
