Transportation
Transportation means moving objects or people from one location to another. A transportation facility is an urban object designated to facilitating the movement of people, cattle, animals and goods from one location to another. Transportation is facilitated by transport infrastructure.
Description
Transportation is divided into private and public transport. An important distinction in the type of transport is mode of transport. In an urban context, the most relevant modes of transport use either the road network 
or the rail network 
. These networks need hubs 
, like train or metro stations, or ports to change modality.
Transport is important since it enables trade between peoples, which in turn establishes civilizations.
Transport plays an important part in economic growth and globalization, but most types cause air pollution and use large amounts of land. Good planning of transport is essential to make traffic flow, and restrain urban sprawl.
However, transportation is generally very vulnerable for security threats. It is an aatractive target because of its importance in society and the presence of large amounts of people or crowds.
Functions
Social
Economic
Mobility
Mobility enables transportation. It is obvious that mobility is very important for the daily life of humans and as such, the continuity of the traffic should be guaranteed. Mobility is fundamental to economic and social activities. More information can be found on the mobility page.
Safety
Specific safety issues in transportation objects, concerns traffic safety.
Security Issues
Security issues associated with transportation objects, are related with the fact that it can be an attractive object for fanatics. This is related with the fact that many transportation objects government assets have public access areas with a high volume of transiting people and with the public attention an attack to a public transportation node will draw. Also, transportation nodes are places with crowds and distracted people, often with valuable luggage. This makes these kinds of urban objects vulnerable for the following security issues:
Measures
The measures for each type of security issue can be found on the respective pages. There are few measures they are specifically suited or unsuited to this kind of urban object, but some general considerations can be mentioned:
- Transportation objects in general know a very high transitory flow. This makes entry/exit control of visitors often very difficult or even impossible. Airports, which do feature entrance/exit control, can afford to do so due to the relative long boarding times (hours instead of minutes for a metro or bus), and the relative high travel costs (hundreds of euros instead of a few euros per passenger).
