Transport Infrastructure

Infrastructure is basic physical and organizational structures needed for the operation of a society or enterprise,[#cite_note-0 [1]] or the services and facilities necessary for an economy to function.[#cite_note-1 [2]] It can be generally defined as the set of interconnected structural elements that provide framework supporting an entire structure of development.

The term typically refers to the technical structures that support a society, such as roads, water supply, sewers, electrical grids, telecommunications, and so forth, and can be defined as "the physical components of interrelated systems providing commodities and services essential to enable, sustain, or enhance societal living conditions."[#cite_note-2 [3]]

In this document, we will only consider transport infrastructure. Transport infrastructure consists of the fixed installations necessary for transport, and may be roads, railways, airways, waterways, and terminals.

== Roads ==A road is a paved surface to facilitate the movement of people or goods with [#_Road_transport road transport] means, such as as automobiles, bicycles, buses, vans or trucks.

Roads on itself are not an interesting security target, but blocking a road will cause problems with the traffic flow and reachability of certain parts of the city or area. This can be prevented by designing a [#_Robustness robust road system] and to detect a disruption and minimize the consequences, using [#_Traffic_monitoring monitoring] and [#_Traffic_management_1 traffic management].

== Rails ==Rails are the infrastructure for [#_Rail_transport rail transport].

As for roads, rails on itself are not an interesting security target, but blocking a railroad will cause large problems with the rail transport.

== Terminals ==Terminals may be used both for interchange of passengers and cargo.

Examples of passenger terminals are airports, railway stations and bus stations.

Examples of terminals for cargo are warehouses, trucking terminals, refueling depots (including fueling docks and fuel stations), and seaports.

All terminals are important for security, since it are potential targets for terrorists. Damage will have a big impact, both economically, life danger of people and by hampering the transportation process heavily. Therefore it is recommended to have an extensive and robust transportation system towards and from the terminal and to locate terminals outside urban areas.

== Traffic intersections ==At traffic intersections, a certain type of traffic infrastructure is intersecting. Mostly this concerns road intersections, though also rail and air intersections are possible.

To prevent incidents at road intersections, the traffic can be controlled with traffic signals.

Traffic intersections are an attractive target for terrorists, since damaging an intersection has larger consequences in terms of disrupting the traffic flow and number of possible injuries than for a road segment.

Possible measures to prevent attacks at important intersections are monitoring with cameras and providing sufficient route alternatives.
