DESCRIPTION:Erik Jenelius\, Ph.D at The Royal Institute of Technology (KTH
 )\, Stockholm\, Sweden\nAs the recent volcanic blockade of European air tr
 avel shows\, disruptions in the transport systems can have severe impacts 
 for affected individuals\, businesses and the society as a whole. In the r
 esearch presented here\, vulnerability is seen as a combination of the sev
 erity and the frequency of unplanned system disruptions\, with a focus on 
 large\, rare events. I will describe model-based studies of different aspe
 cts of vulnerability\, in particular the dichotomy of system efficiency an
 d user equity\, applied to the Swedish road network. The scenarios studied
  include both closures of single road links and disruptions of extended ar
 eas. I will also address the issue of how to value the delays that are inc
 urred by network disruptions and\, using an activity-based modelling appro
 ach\, I illustrate that these delay costs may be considerably higher than 
 the ordinary value of time\, in particular the first few days after the ev
 ent when travel conditions are uncertain.\n\nBio\n\nErik Jenelius received
  the M.Sc. in Engineering Physics at The Royal Institute of Technology (KT
 H)\, Stockholm\, in 2004. From June 2005 to January 2006 he worked for the
  City of Stockholm with the evaluation of the Stockholm congestion pricing
  trials. Since February 2006 he is a Ph.D. Candidate at the Division of Tr
 ansport and Location Analysis\, KTH. He is working in a project concerning
  road network vulnerability analysis\, the main aim of which is to develop
  the methodology for vulnerability analyses with application to real large
 -scale road networks. In 2008 he received the Lic.Eng. degree in Infrastru
 cture from KTH. His research interests include road network vulnerability\
 , critical infrastructure protection\, transport reliability\, transport e
 conomics and complex networks.
