Mass transit systems are essential for facilitating the movement of large numbers of people within urban areas. They include various modes of transportation such as buses, subways, and trains, which help reduce traffic congestion and lower environmental impact. By providing affordable and efficient travel options, these systems enhance accessibility and promote economic growth in cities. In addition to improving mobility, mass transit systems contribute to social equity by offering transportation solutions for those without private vehicles. Cities like New York and Tokyo have developed extensive networks that serve millions daily, showcasing the importance of reliable public transport in modern urban life.
