Public transportation refers to systems of transport that are available for use by the general public, typically consisting of buses, trains, subways, and ferries. These services are designed to provide affordable and efficient travel options for individuals, reducing the reliance on personal vehicles and helping to alleviate traffic congestion in urban areas. In addition to being cost-effective, public transportation plays a crucial role in promoting environmental sustainability. By encouraging the use of shared transport, it helps to lower greenhouse gas emissions and reduce the overall carbon footprint of cities. Many cities around the world are investing in expanding and improving their public transit systems to enhance accessibility and convenience for all residents.
