Light rail is a mode of rail-based transport, usually urban in nature. When compared to heavy rail systems like commuter rail or rapid transit (subway), light rail systems are typically designed to carry fewer passengers and are capable of operating in mixed traffic or on routes that are not entirely grade-separated. Systems typically take one of four forms: the "first-generation" legacy systems, the "second-generation" modern light rail systems, streetcars, and hybrid rail systems. All of the systems use similar technologies, and some systems blur the lines between the different forms.
The United States is serviced by a wide array of public transportation, including various forms of bus, rail, ferry, and sometimes, airline services. Most established public transit systems are located in central, urban areas where there is enough density and public demand to require public transportation. In more auto-centric suburban localities, public transit is normally, but not always, less frequent and less common. Most public transit services in the United States are either national, regional/commuter, or local, depending on the type of service. Sometimes "public transportation" in the United States is an umbrella term used synonymously with "alternative transportation", meaning any form of mobility that excludes driving alone by automobile. This can sometimes include carpooling, vanpooling, on-demand mobility, infrastructure that is oriented toward bicycles, and paratransit service. There is public transit service in most US cities.
