A junction, when discussed in the context of transport, is a location where traffic can change between different routes, directions, or sometimes modes, of travel.
The word "junction" derives from Latin iunctus, past participle of iungere, to join. The word "junction" in this context may also refer to:
Historically, many cities and market towns developed wherever there was a junction. A road intersection offered opportunities for rest or trade for travellers and merchants. Towns sprang up to accommodate this; the first such in Europe were probably at intersections of the Roman roads.
A similar effect came with the growth of rail transport; so-called railway towns grew up near major railway junctions –originally to accommodate railway workers, but expanding into fully functioning settlements over time.
Junctions also developed where different modes of transport intersected, e.g. canal and rail.
There are many types of different junction for road transport and rail transport (including metro and rapid transit systems). If many of these are contained in a small area, and where passengers can change from one transport mode to the other in them, it is said to be a transport hub.

A roundabout, a rotary and a traffic circle are types of circular intersection or junction in which road traffic is permitted to flow in one direction around a central island, and priority is typically given to traffic already in the junction.
An intersection or an at-grade junction is a junction where two or more roads converge, diverge, meet or cross at the same height, as opposed to an interchange, which uses bridges or tunnels to separate different roads. Major intersections are often delineated by gores and may be classified by road segments, traffic controls and lane design.
Barking is an interchange station serving the town of Barking, east London. It is served by London Underground, London Overground and National Rail main line services. It is located on Station Parade, in the town centre.
A junction, in the context of rail transport, is a place at which two or more rail routes converge or diverge. The physical connection between the tracks of the two routes is provided by turnouts and signalling.
Choa Chu Kang, alternatively spelled Chua Chu Kang and often abbreviated as CCK, is a planning area and residential town located at the northwestern point of the West Region of Singapore. The town shares borders with Sungei Kadut to the north, Tengah to the southwest, Bukit Batok to the southeast, Bukit Panjang to the east and the Western Water Catchment to the west. Choa Chu Kang New Town is separated into two portions by the Kranji Expressway.
Chatswood railway station is a railway station located in the Sydney suburb of Chatswood. It is served by Sydney Trains services; the T1 North Shore & Western Line and the T9 Northern Line, and the Sydney Metro's North West & Bankstown Line.
A median strip, central reservation, roadway median, or traffic median is the reserved area that separates opposing lanes of traffic on divided roadways such as divided highways, dual carriageways, freeways, and motorways. The term also applies to divided roadways other than highways, including some major streets in urban or suburban areas. The reserved area may simply be paved, but commonly it is adapted to other functions; for example, it may accommodate decorative landscaping, trees, a median barrier, or railway, rapid transit, light rail, or streetcar lines.
In civil engineering, grade separation is a method of aligning a junction of two or more surface transport axes at different heights (grades) so that they will not disrupt the traffic flow on other transit routes when they cross each other. The composition of such transport axes does not have to be uniform; it can consist of a mixture of roads, footpaths, railways, canals, or airport runways. Bridges, tunnels, or a combination of both can be built at a junction to achieve the needed grade separation.
The road hierarchy categorizes roads according to their functions and capacities. While sources differ on the exact nomenclature, the basic hierarchy comprises freeways, arterials, collectors, and local roads. Generally, the functional hierarchy can more or less correspond to the hierarchy of roads by their owner or administrator.
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.
Rail freight transport is the use of railways and trains to transport cargo as opposed to human passengers.
The M5 is an expressway in the City of Cape Town Metropolitan Municipality, South Africa. It connects Milnerton on the Western Seaboard in the north to Muizenberg in the south, and crosses both the N1 and the N2. For part of its length, from the N1 interchange to Plumstead, it is a limited-access freeway (motorway). From Mowbray to Muizenberg it is parallel to the M4 Main Road.
The Metropolitan Adelaide Transport Study, or "MATS Plan" as it became known, was a comprehensive transport plan released in 1968 proposing a number of road and rail transport projects for the metropolitan area of Adelaide, South Australia.
An interchange station or a transfer station is a train station for more than one railway route in a public transport system that allows passengers to change from one route to another, often without having to leave a station or pay an additional fare.
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 an unimodal hub.
A journey planner, trip planner, or route planner is a specialized search engine used to find an optimal means of travelling between two or more given locations, sometimes using more than one transport mode. Searches may be optimized on different criteria, for example fastest, shortest, fewest changes, cheapest. They may be constrained, for example, to leave or arrive at a certain time, to avoid certain waypoints, etc. A single journey may use a sequence of several modes of transport, meaning the system may know about public transport services as well as transport networks for private transportation. Trip planning or journey planning is sometimes distinguished from route planning, which is typically thought of as using private modes of transportation such as cycling, driving, or walking, normally using a single mode at a time. Trip or journey planning, in contrast, would make use of at least one public transport mode which operates according to published schedules; given that public transport services only depart at specific times, an algorithm must therefore not only find a path to a destination, but seek to optimize it so as to minimize the waiting time incurred for each leg. In European Standards such as Transmodel, trip planning is used specifically to describe the planning of a route for a passenger, to avoid confusion with the completely separate process of planning the operational journeys to be made by public transport vehicles on which such trips are made.
The city of Karachi is a major transport hub of Pakistan. The Karachi port and airport are major gateways to Pakistan. The Karachi Railway stations transports the major part of Pakistan's trade with other countries.
Transport or transportation is the intentional movement of humans, animals, and goods from one location to another. Modes of transport include air, land, water, cable, pipelines, and space. The field can be divided into infrastructure, vehicles, and operations. Transport enables human trade, which is essential for the development of civilizations.
Since the early 2000s, Doha, the capital of Qatar has been undergoing an extensive expansion in its transportation network including the addition of new highways, the construction of a new airport, and the addition of the Doha metro. These projects are meant to keep up with the population's rapid growth, which has strained the country's current infrastructure.
Terminology related to road transport—the transport of passengers or goods on paved routes between places—is diverse, with variation between dialects of English. There may also be regional differences within a single country, and some terms differ based on the side of the road traffic drives on. This glossary is an alphabetical listing of road transport terms.
