Road infrastructures constitute the backbone of the transportation system in modern societies, and they play a major role for socio-economic developments. At the same time, even minor localised disruptions, due to e.g. traffic restrictions or an incident on a road section, can propagate through the road network and lead to intense traffic interferences resulting into considerable economic costs and negative environmental consequences. Therefore, it is essential to assess the ability of road infrastructures to cope with traffic pressure under extreme conditions. More recently, there has been an increasing research interest in transportation systems security, and various studies on road networks’ vulnerability have been carried out. The objective of this study is to derive a model for identifying which parts of a network are most critical, i.e. which parts when removed or disabled cause the greatest disruption to the traffic flow around the remainder of the network. Such information can then be used to improve the reliability of the transportation system. The developed model is then used to assess a specific part of Belfast Metropolitan Area road network and identified the most critical components of the corresponding transportation network
