Mass Rapid Transit (MRT) refers to a high-capacity public transportation system designed to move large numbers of people quickly and efficiently within urban areas. It typically includes trains, subways, and light rail systems that operate on dedicated tracks, reducing traffic congestion and travel time. MRT systems are often characterized by frequent service, multiple stops, and affordable fares. MRT systems are essential for sustainable urban development, as they encourage the use of public transport over private vehicles. Cities like Singapore, Tokyo, and New York have successfully implemented MRT networks, contributing to reduced pollution and improved accessibility for residents and visitors alike.
