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.
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 will typically operate under the following transportation objects:
|Transportation network object type||Description||Icon|
|Road network||A series of roads connecting the constituents parts of the urban environment and its surrounding hinterland, and urban areas with the wider region and country. The road network consists of a range of different hierarchical standards of road (e.g. single street, dual carriageway, highway/motorway, etc).|
|Rail network||The rail network consists of the infrastructure connecting population nodes through a series of rail corridors. The rail network facilitates public transportation services, including train, metro and tram services.|
|Hubs||A transport hub is a connection point in the wider transport network where the public can change transport modes. Hubs include stations for train, metro and tram systems, or sea/air ports for water or air transport to change modality.|
Transport is important because it enables communication, trade and other forms of exchange between people, that 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 manage traffic flows, and restrain urban sprawl. Yet, transportation is generally very vulnerable for security threats. It is an attractive target because of its importance in society and the presence of large amounts of people or crowds.
High quality transport links ensure that communities can access basic services, facilities, and employment opportunities. The connectivity provided by such links promotes social inclusion, can reduce social isolation, and enhances quality of life.
From the social point of view, vulnerability assessment and deriving of resilience requirements for urban planning is a complex process in the case of transportation infrastructure. This is so because common indicators point into different directions based on the following checklists:
- List of indicators for assessment of subjective protection requirements of critical infrastructure;
- Types of impact of critical infrastructure failure on citizens and society and needs to protect it;
- Societal aspects of failure of critical services.
For example, citizens can perceive direct benefit of transportation infrastructure, which should increase felt risks to urban infrastructure and needs to protect. However, transportation is an infrastructure that allows to considerable extent for perception of own capability to control the infrastructure. This should decrease citizens’ felt risks to that infrastructure and needs to protect, including reduced acceptance levels for security-enhancing measures in urban planning. At the same time, the high degree of exposure to transportation infrastructure should again increases citizens’ felt risks to urban infrastructure and needs to protect, as well as felt individual dependence on transportation infrastructure. This makes it important to involve citizens in related urban-object risk assessment. VITRUV identified a set of practical methods for such citizen participation.
Transportation is a crucial component of every economy since it enables the transport of resources from one location to the other, enabling people and societies as a whole to produce welfare. Transported resources can range from material objects such as natural resources and manufactured products to labour, knowledge and skills in the form of people.. Efficient transport systems provide economic and social benefits such as a better accessibility to markets, employment, knowledge (schools) and investors. These benefits are the result of a reduction in transportation costs and lead to direct economic impacts which can be measured in terms of employment, added value, investment costs, etc. Note, however, that these transportation costs are not just the result of physical infrastructure such as roads and airports, but also of many other different kind of obstacles such as tariffs, language and culture barriers. The economic impact of transportation extends in most cases beyond these direct effects due to the further rounds of economic activity as a result of the transportation of goods, the so-called indirect economic effects. Transportation, however, also has a social and an environmental impact, which is not in all cases positive. Congestion, traffic accidents, environmental pollution and land consumption are well-known examples of these social or external effects of transportation.
The economic impact of transportation can be assessed from both a macroeconomic perspective and a micro-economic perspective with the help of economic tools such as the social cost-benefit analysis in case investments in transportation have to be appraised. At the micro-economic level, transportation is linked to the costs of transportation for individual agents, while at a macroeconomic level the importance of transportation for an economy as a whole is assessed. The economic impact of transportation is directly linked to the location of an urban object/environment. Locations with low levels of accessibility such as cities surrounded by mountains tend to have higher costs for many goods and services, limiting the welfare of individuals and society.
In general, security threats will have a negative effect on the mobility of individuals, and in extreme cases on the mobility of a society as whole. As a result, the positive economic impact of an efficient transportation system will be partly reversed (the economic impact of security threats). Security measures such as directing traffic flows and access control, can reduce these negative impacts, but can also have a negative impact on the efficiency of transportation networks, also referred to as the economic impact of security measures.
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. In developed and developing nations, a large fraction of people travel daily for work, shopping and social reasons. More information can be found on the mobility page.
Transportation can either mean transportation of people or transportation of goods. For the first, different modes of transport are available, such as road transport (walking, cycling, car driving, buses) and rail transport. Important for passenger transport is also public transport. Especially public transport has a high security risk. The past decades have shown the vulnerability of the public transport system for terrorist attacks by several tragic incidents, e.g. the 2004 Madrid train bombings, the 2010 Moscow Metro bombings, and several attacks on the London Underground.
The transportation of goods is called freight transport and logistics. It concerns the distribution of goods from the source to their destination, such as warehouses or terminals for further distribution to e.g. shops. This can involve different modes of transport as well.
Specific safety issues in transportation objects concern mainly traffic safety.
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. The presence of a high volume of travellers makes graffiti visible to a large audience. This makes these kinds of urban objects vulnerable for the following security issues:
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 or even screening 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).
