Hub

Hub

A transport hub (also transport interchange) is a place where passengers and cargo are exchanged between vehicles or between transport modes.

Description

Public transport hubs include train stations, rapid transit stations, bus stops, tram stop, airports and ferry slips. Freight hubs include classification yards, seaports and truck terminals, or combinations of these. For private transport, the parking lot functions as a hub . For the purposes of Urban Securipedia, we focus on two types of hub; stations and ports:

Hub type	Description	Icon
Station	A stopping place on a public transportation route for trains, metro and tram systems, often consisting of a platform and a building or group of buildings depending on scale. The station allows passengers to embark or disembark from the mode of transport.
Port	A port includes both airports and sea ports, and refers to the area and associated structures where planes land or take-off, and where ferrys dock or depart. They allow for modality change by passengers, etc.

Where any aspect of the following sections on this page are considered to be specific to one of the hub types listed above, the relevant icon will be displayed.

Functions

Social

• Transportation has always played an important role in influencing the formation of urban societies. Although other facilities like availability of food and water, played a major role, the contribution of transportation can be seen clearly from the formation, size and pattern, and the development of societies, especially urban centres (NPTEL May 24, 2006).

Economic

• Economics involves production, distribution and consumption of goods and services. People depend upon the natural resources to satisfy the needs of life but due to non uniform surface of earth and due to difference in local resources, there is a lot of difference in standard of living in different societies. So there is an immense requirement of transport of resources from one particular society to other. These resources can range from material things to knowledge and skills like movement of doctors and technicians to the places where there is need of them (NPTEL May 24, 2006);
• Infrastructure in the form of transport networks has a direct impact on the scale of local market areas. For example the spatial extent of retail and other services' catchment areas is partly a function of the costs of travel by customers. In fact a hierarchy of services provision/facilities exists determined by the transport network. This is most evident in retailing, e.g. large retail superstore, local supermarket, small corner shop;
• Accessibility impacts on the spatial distribution of employment and residential preferences. In terms of location, there is likely to be a higher demand for land/property that has good accessibility both to it, and to other services/facilities/infrastructure etc. In as much as accessibility can influence profitability then this is reflected in land prices/rents.

Mobility

• In developed and developing nations, a large fraction of people travel daily for work, shopping and social reasons.

Safety
