Public transportation or mass transit generally refers to all transportation modes that are open to the public and provide transportation services, and is usually paid for as a commercial service, but there are few exceptions to free transportation. A public transportation system is composed of physical elements such as a passage, transportation means, and station facilities. In a broad sense, public transportation comprises transportation modes such as civil aviation, railways, highways, water transportation and the like; the narrow public transportation means transportation modes such as buses, rail transit, ferries, ropeways and the like which are operated in a line-defined manner in an urban area. As further categorized, public transportation includes both personnel and cargo transportation, while public transportation refers only to personnel transportation and is limited to urban area-wide personnel transportation, and in some instances, public transportation is synonymous with public transportation.
