Public transport (also known as public transportation, public transit, mass transit, or simply transit) is a system of transport for passengers by group travel systems available for use by the general public unlike private transport, typically managed on a schedule, operated on established routes, and that charge a posted fee for each trip.[1][2] There is no rigid definition; the Encyclopædia Britannica specifies that public transportation is within urban areas,[3] and air travel is often not thought of when discussing public transport—dictionaries use wording like "buses, trains, etc."[4]Examples of public transport include city buses, trolleybuses, trams (or light rail) and passenger trains, rapid transit(metro/subway/underground, etc.) and ferries. Public transport between cities is dominated by airlines, coaches, and intercity rail. High-speed rail networks are being developed in many parts of the world.
Most public transport systems run along fixed routes with set embarkation/disembarkation points to a prearranged timetable, with the most frequent services running to a headway (e.g.: "every 15 minutes" as opposed to being scheduled for any specific time of the day). However, most public transport trips include other modes of travel, such as passengers walking or catching bus services to access train stations.[5] Share taxis offer on-demand services in many parts of the world, which may compete with fixed public transport lines, or complement them, by bringing passengers to interchanges. Paratransit is sometimes used in areas of low demand and for people who need a door-to-door service.[6] Urban public transit differs distinctly among Asia, North America, and Europe. In Asia, profit-driven, privately owned and publicly traded mass transit and real estate conglomerates predominantly operate public transit systems.[7][8] In North America, municipal transit authorities most commonly run mass transit operations. In Europe, both state-owned and private companies predominantly operate mass transit systems.
For geographical, historical and economic reasons, differences exist internationally regarding use and extent of public transport. While countries in the Old World tend to have extensive and frequent systems serving their old and dense cities, many cities of the New World have more sprawl and much less comprehensive public transport.[citation needed] The International Association of Public Transport (UITP) is the international network for public transport authorities and operators, policy decision-makers, scientific institutes and the public transport supply and service industry. It has 3,400 members from 92 countries from all over the globe.
In recent years, some high-wealth cities have seen a decline in public transport usage.[citation needed] A number of sources attribute this trend to the rise in popularity of remote work, ride-sharing services, and car loans being relatively cheap across many countries. Major cities such as Toronto, Paris, Chicago, and London have seen this decline and have attempted to intervene by cutting fares and encouraging new modes of transportation, such as e-scooters and e-bikes.[9] Because of the reduced emissions and other environmental impacts of using public transportation over private transportation, many experts have pointed to an increased investment in public transit as an important climate change mitigation tactic
Conveyances designed for public hire are as old as the first ferries, and the earliest public transport was water transport: on land people walked (sometimes in groups and on pilgrimages, as noted in sources such as the Bible and The Canterbury Tales) or (at least in Eurasia and Africa) rode an animal.[11] Ferries appear in Greek mythology—corpses in ancient Greece were buried with a coin underneath their tongue to pay the ferryman Charon to take them to Hades.[12] Some historical forms of public transport include the stagecoach, traveling a fixed route between coaching inns, and the horse-drawn boat carrying paying passengers, which was a feature of European canals from their 17th-century origins. The canal itself as a form of infrastructure dates back to antiquity – ancient Egyptians certainly used a canal for freight transportation to bypass the Aswan cataract – and the Chinese also built canals for water transportation as far back as the Warring States period[13] which began in the 5th century BCE. Whether or not those canals were used for-hire public transport remains unknown; the Grand Canal in China (begun in 486 BCE) served primarily for shipping grain.
The omnibus, the first organized public transit system within a city, appears to have originated in Paris, France, in 1662,[14] although the service in question, Carrosses à cinq sols, failed a few months after its founder, Blaise Pascal, died in August 1662; omnibuses are next known to have appeared in Nantes, France, in 1826. The omnibus was introduced to London in July 1829.[15] The first passenger horse-drawn railway opened in 1806: it ran between Swansea and Mumbles in southwest Wales in the United Kingdom.[16] In 1825 George Stephensonbuilt the Locomotion for the Stockton and Darlington Railway in northeast England, the first public steam railway in the world. The world's first steam-powered underground railway opened in London in 1863.[17] In the following hundred years, the transportation and technical equipment provided by industrial development for the city have been continuously updated, which has accelerated the process of modernization of urban public transportation, and the transportation with backward performance has gradually been eliminated. The stagecoach and railcar were successively replaced by trams, trolleybuses and buses.
The first successful electric streetcar was built for 11 miles of track for the Union Passenger Railway in Tallahassee, Florida in 1888. Electric streetcars could carry heavier passenger loads than predecessors, which reduced fares and stimulated greater transit use. Two years after the Richmond success, over thirty two thousand electric streetcars were operating in America. Electric streetcars also paved the way for the first subway system in America. Before electric streetcars, steam powered subways were considered. However, most people believed that riders would avoid the smoke filled subway tunnels from the steam engines. In 1894, Boston built the first subway in the United States, an electric streetcar line in a 1.5-mile tunnel under Tremont Street's retail district. Other cities such as New Jersey quickly followed, constructing thousands of miles of subway in the following decades.[18] Since the 2002s, maritime transport has diminished its role. However, even today, traditional ships and hydrofoils are used on the routes.
In March 2020, Luxembourg abolished fares for trains, trams and buses and became the first country in the world to make all public transport free.
