PUBLIC TRANSPORTATION

Public transport (or public transportation, public transit or mass transit) comprises passenger transportation services which are available for use by the general public, as opposed to modes for private use such as automobiles or vehicles for hire. Some services are free though most charge some sort of fare.
Public transportation can consist of buses, subways, trolleys and light rail, commuter trains, van pool services, paratransit services for senior citizens and people with disabilities, ferries, water taxis, or monorails.

Public transport is provided by a company or authority that operate a fleet of vehicles. They may or may not be regulated or subsidized by authorities. The infrastructure used may be exclusive, or shared with private vehicles. Higher public transport ridership is generally seen in urban areas, and less in North America and Australia. The environmental impact of public transport is lower than private due to less use of land area and energy, at the same time reducing sprawl. Public transportation systems are also significantly safer than private road systems.
