Transport Infrastructure

Transport Infrastructure
Transport infrastructure consists of the fixed installations necessary for transport and includes 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. A rail road which connects two locations is also called a rail line.
As for roads, rails on itself are not an interesting security target, but blocking a railroad will cause large problems with the rail transport.
Pedestrian / Bicycle paths
Pedestrian paths or sidewalks, curbs, pavements, footpaths or platforms are paths alongside a road designated for pedestrians. Bicycle paths comprises of several different forms of cycling infrastructure, from non-segregated pathways aligned next to the road to segregated cycle facilities.
Segregated cycle facilities are a form of cycling infrastructure consisting of marked lanes, tracks, shoulders and paths designated for use by cyclists and from which motorised traffic is generally excluded. The term includes bike lanes, cycle tracks, separated bike lanes, road shoulders and side paths located within a road right-of-way[1].
Urban waterways
Inter and intra urban transport over waterways such as canals, rivers or other waterways forms a smaller although still important aspect of the urban transport system. For port cities such as Rotterdam, Antwerp or Hamburg the waterway system is of vital importance for their economic development. Security of waterways are important for securing the urban area and are described in more detail on the specific page.
Subway system
A rapid transit, underground, subway, elevated railway, metro or metropolitan railway system is an electric passenger railway in an urban area with a high capacity and frequency, and grade separation from other traffic. Rapid transit systems are typically located either in underground tunnels or on elevated rails above street level[2].
Bridges and fly-overs
A bridge is a structure built to span physical obstacles such as a body of water, valley, or road, for the purpose of providing passage over the obstacle[3]. A flyover is a bridge, road, railway or similar structure that crosses over another road or railway forming a grade separation[4]. Various different designs are possible depending on the length of the span and the conditions of the site.
Bridges and fly-overs form a vital and vulnerable element of a transport system since blocking can cause serious disruptions in the transportation system. Security risks are high since bridges and fly-overs are generally difficult to reach in case of emergencies.
Terminals
A terminal is any location where freight and passengers either originates, terminates, or is handled in the transportation process. Terminals are central and intermediate locations in the movements of passengers and freight. They often require specific facilities and equipment to accommodate the traffic they handle[5].
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.
Airports
An airport is a location where aircraft such as fixed-wing aircraft, helicopters, and blimps take off and land. Aircraft may be stored or maintained at an airport. An airport consists of at least one surface such as a runway for a plane to take off and land, a helipad, or water for takeoffs and landings, and often includes buildings such as control towers, hangars and terminal buildings[6].
Train station
A train station, also called a railroad station (mainly in the United States) or railway station (mainly in the British Commonwealth) and often shortened to just station, is a railway facility where trains regularly stop to load or unload passengers or freight. It generally consists of a platform next to the track and a station building (depot) providing related services such as ticket sales and waiting rooms[7].
Metro station
A metro station or subway station is a railway station for a rapid transit system, often known by names such as "metro", "underground" and "subway".
Metro stations are very vulnerable for terroristic attacks, as can be seen from this list with underground attacks attacks on the London underground.
Bus terminal
A bus terminus is a designated place where a bus or coach starts or ends its scheduled route .
Freight terminal
A freight terminal is a processing node for freight. Most freight terminals are located at ports. They may include airports, seaports, railroad terminals, and trucking terminals. Freight is usually loaded onto and off the transport[8].
Sea port
A sea port (or shortly port) is a location on a coast or shore containing one or more harbors where ships can dock and transfer people or cargo to or from land[9].
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.
