Kostnader för störningar i infrastrukturen: metodik och fallstudier på väg och järnväg

Joakim Ahlberg

The purpose of this study is to illustrate the methodology that can be used in calculations of the cost to society when disruptions in the infrastructure occurs, specifically for traffic on road and rail. The principles and values that are recommended to be used in social cost-benefit analyses (CBA) in the Swedish transport sector are proposed by the ASEK-group (a working-group addressing issues on the application of CBA in the transport sector), and decided by the Swedish Transport Administration. They will be taken as given on the cost side of the CBA in this study, there will not be a benefit side since the interest for this study lies expressively on the cost side. This study is thus not a normative analysis, the aim is instead to study and apply methodologies for valuing (in monetary terms) the consequences of already occurred disturbances. The various ASEK-values require information about several aspect of the trips when calculating the value of travel time and transport time, as well as when calculating the delays and the value of travel time savings in congestion. Even though the ASEK-values are recommended by the Swedish Transport Administration, they are also questioned, especially for freight transport. This is also addressed in the report.



Cost Benefit Analysis (CBA) workshop in Stockholm

An open seminar and workshop in Stockholm will be held on 25-26 April 2018. The workshop deals with the use of CBA as a basis for decision-making in the public sector. The workshop is organized by, among others, Professor Jan-Eric Nilsson, VTI.
