Light rail vehicles (LRVs) are a type of public transportation that operates on tracks, typically in urban areas. They are designed to carry passengers over short to medium distances and can run on dedicated tracks or share roadways with other vehicles. LRVs are often quieter and more energy-efficient than traditional buses or trains. These vehicles usually have a lower capacity than heavy rail systems, making them suitable for cities with moderate passenger demand. Light rail systems, like those found in Portland or San Francisco, help reduce traffic congestion and promote sustainable urban development by providing an alternative to car travel.
