A transport hub is a place where passengers and cargo are exchanged between vehicles and/or between transport modes. Public transport hubs include railway stations, rapid transit stations, bus stops, tram stops, airports and ferry slips. Freight hubs include classification yards, airports, seaports and truck terminals, or combinations of these. For private transport by car, the parking lot functions as a unimodal hub.
Historically, an interchange service in the scheduled passenger air transport industry involved a "through plane" flight operated by two or more airlines where a single aircraft was used with the individual airlines operating it with their own flight crews on their respective portions of a direct, no-change-of-plane multi-stop flight. In the U.S., a number of air carriers including Alaska Airlines, American Airlines, Braniff International Airways, Continental Airlines, Delta Air Lines, Eastern Airlines, Frontier Airlines (1950-1986), Hughes Airwest, National Airlines (1934-1980), Pan Am, Trans World Airlines (TWA), United Airlines and Western Airlines previously operated such cooperative "through plane" interchange flights on both domestic and/or international services with these schedules appearing in their respective system timetables.

Delta Air Lines pioneered the hub and spoke system for aviation in 1955 from its hub in Atlanta, Georgia, United States, [3] in an effort to compete with Eastern Air Lines. FedEx adopted the hub and spoke model for overnight package delivery during the 1970s. When the United States airline industry was deregulated in 1978, Delta's hub and spoke paradigm was adopted by several airlines. Many airlines around the world operate hub-and-spoke systems facilitating passenger connections between their respective flights.
Intermodal passenger transport hubs in public transport include bus stations, railway stations and metro stations, while a major transport hub, often multimodal (bus and rail), may be referred to as a transport centre or, in American English, as a transit center. [4] Sections of city streets that are devoted to functioning as transit hubs are referred to as transit malls. In cities with a central station, that station often also functions as a transport hub in addition to being a railway station.
Journey planning involving transport hubs is more complicated than direct trips, as journeys will typically require a transfer at the hub. Modern electronic journey planners for public transport have a digital representation of both the stops and transport hubs in a network, to allow them to calculate journeys that include transfers at hubs.
Airports have a twofold hub function. First they concentrate passenger traffic into one place for onward transportation. This makes it important for airports to be connected to the surrounding transport infrastructure, including roads, bus services, and railway and rapid transit systems. Secondly some airports function as intra-modular hubs for the airlines, or airline hubs. This is a common strategy among network airlines who fly only from limited number of airports and usually will make their customers change planes at one of their hubs if they want to get between two cities the airline does not fly directly between.
Airlines have extended the hub-and-spoke model in various ways. One method is to create additional hubs on a regional basis, and to create major routes between the hubs. This reduces the need to travel long distances between nodes that are close together. Another method is to use focus cities to implement point-to-point service for high traffic routes, bypassing the hub entirely.
There are usually three kinds of freight hubs: sea-road, sea-rail and road-rail, though they can also be sea-road-rail. With the growth of containerization, intermodal freight transport has become more efficient, often making multiple legs cheaper than through services—increasing the use of hubs. [ citation needed ]

The airport is in the Honolulu census-designated place 3 miles (5 km) northwest of Honolulu's central business district. The airport covers 4,220 acres, more than 1% of Oahu's land.
The spoke–hub distribution paradigm is a form of transport topology optimization in which traffic planners organize routes as a series of "spokes" that connect outlying points to a central "hub". Simple forms of this distribution/connection model contrast with point-to-point transit systems, in which each point has a direct route to every other point, and which modeled the principal method of transporting passengers and freight until the 1970s. Delta Air Lines pioneered the spoke–hub distribution model in 1955, and the concept revolutionized the transportation logistics industry after Federal Express demonstrated its value in the early 1970s. In the late 1970s the telecommunications and information technology sector subsequently adopted this distribution topology, dubbing it the star network network topology.
Minot International Airport is in Ward County, North Dakota, United States, two miles north of the city of Minot, which owns it. The National Plan of Integrated Airport Systems for 2011–2015 categorized it as a primary commercial service airport.
Intermodal passenger transport, also called mixed-mode commuting, involves using two or more modes of transportation in a journey. Mixed-mode commuting is often used to combine the strengths of various transportation options. A major goal of modern intermodal passenger transport is to reduce dependence on the automobile as the major mode of ground transportation and increase use of public transport. To assist the traveller, various intermodal journey planners such as Rome2rio and Google Transit have been devised to help travellers plan and schedule their journey.
An airline hub or hub airport is an airport used by one or more airlines to concentrate passenger traffic and flight operations. Hubs serve as transfer points to help get passengers to their final destination. It is part of the hub-and-spoke system. An airline may operate flights from several non-hub (spoke) cities to the hub airport, and passengers traveling between spoke cities connect through the hub. This paradigm creates economies of scale that allow an airline to serve city-pairs that could otherwise not be economically served on a non-stop basis. This system contrasts with the point-to-point model, in which there are no hubs and nonstop flights are instead offered between spoke cities. Hub airports also serve origin and destination (O&D) traffic.
Toronto Pearson International Airport is an international airport located in Mississauga, Ontario, Canada. It is the main airport serving Toronto, its metropolitan area, and the surrounding region known as the Golden Horseshoe. The airport is named in honour of Lester B. Pearson, who served as the 14th Prime Minister of Canada (1963–1968) and received the Nobel Peace Prize in 1957 for his humanitarian work in peacekeeping.
Point-to-point transit is a transportation system in which a plane, bus, or train travels directly to a destination, rather than going through a central hub. This differs from the spoke-hub distribution paradigm in which the transportation goes to a central location where passengers change to another train, bus, or plane to reach their destination.

Greater Kuala Lumpur is conterminous with the Klang Valley, an urban conglomeration consisting of the city of Kuala Lumpur, as well as surrounding towns and cities in the state of Selangor. The Klang Valley has the country's largest airport, the Kuala Lumpur International Airport (KLIA), as well as the country's largest intermodal transport hub and railway station, Kuala Lumpur Sentral.
In public transportation, schedule adherence or on-time performance refers to the level of success of the service remaining on the published schedule. On time performance, sometimes referred to as on time running, is normally expressed as a percentage, with a higher percentage meaning more vehicles are on time. The level of on time performance for many transport systems is a very important measure of the effectiveness of the system.
Memphis, Tennessee has developed into a major Mid-American commercial and transportation hub because of its location on the Mississippi River and a convergence of numerous rail and highway links. Four rail and highway bridges cross the Mississippi River at Memphis. In addition, Memphis International Airport has become the world's largest airfreight terminal.

It is also used by the majority of members of the Oneworld and a few SkyTeam alliances along with several long-haul non-affiliated airlines. It is also the base for Virgin Atlantic.
Transport in Greater Nagoya (Chūkyō) is similar to that of the Tokyo and Osaka, but is more automobile oriented, as the urban density is less than Japan's two primary metropolises, and major automobile manufacturers like Toyota are based here. Still, compared to most cities of its size worldwide it has a considerable rail transport network with 3 million passenger trips daily, with a similar density and extent of passenger rail to London or New York City, complemented with highways and surface streets for private motor transport. It includes public and private rail and highway networks; airports for international, domestic, and general aviation; buses; motorcycle delivery services, walking, bicycling, and commercial shipping. The nexus of the public transport system is Nagoya Station. Every region of Greater Nagoya, also known as the Chūkyō Metropolitan Area (中京圏), has rail or road transport services, and the area as a whole is served by sea and air links.
Transport in Fukuoka-Kitakyushu is similar to that of other large cities in Japan, but with a high degree of private transport. The region is a hub of international ferry services and has a high degree of air connectivity and a considerable rail transport network, complemented with highways and surface streets. It includes public and private rail and highway networks; airports for international, domestic, and general aviation; buses; motorcycle delivery services, walking, bicycling, and commercial shipping. The foci of the public transport system are Hakata Station, Tenjin Station, and Kokura Station, in Fukuoka and Kitakyushu cities respectively. Between these two cities lies a more sparse weblike regional rail network.
A shuttle train is a train that runs back and forth between two points, especially if it offers a frequent service over a short route. Shuttle trains are used in various ways, in various parts of the world. They commonly operate as a fixed consist, and run non-stop between their termini. They can be used to carry passengers, freight, or both.
The Northern Virginia region is served by numerous mediums of transit. Transportation in the region is overseen by the Northern Virginia Transportation Commission and the Northern Virginia Transportation Authority.
Los Angeles International Airport has more than 150 gates in nine passenger terminals arranged in the shape of the letter U or a horseshoe. On the landside of the airport, LAX Shuttle route A buses allow passengers to move between all terminals. On the airside, various pedestrian corridors allow passengers to move between all terminals on foot without having to exit and reenter airport security. Additionally, by early 2025, the airport will be served by the LAX Automated People Mover, which will connect terminals to one another on the landside, along with providing connections to the LAX Consolidated Rent-A-Car Facility, parking facilities, and the LAX/Metro Transit Center station, which will be served by the Los Angeles Metro Rail system and public bus routes. In addition to these terminals, there are 2 million square feet (190,000 m2) of cargo facilities.
