Light Rail Transit (LRT) is a form of urban public transportation that uses light rail vehicles to move passengers. It typically operates on dedicated tracks, often in city areas, and can be either above ground or underground. LRT systems are designed to be efficient and environmentally friendly, providing a reliable alternative to buses and cars. LRT systems are commonly found in many cities around the world, including cities like Portland and Toronto. They help reduce traffic congestion and lower greenhouse gas emissions by encouraging public transit use. Additionally, LRT can stimulate economic development in surrounding areas.
