Före och efter: uppföljning av en järnvägsinvestering i Oslo

Download

VTI has been commissioned to make an ex post evaluation of a new double track between Asker and Sandvika to the southwest of Oslo. This is one out of three parcels in a package of railway investments in this area. The decision to implement the project was taken by the Norwegian parliament, Stortinget, in 2001 and the 9,5 km long section, most of which comprises tunnels, was opened for traffic in 2005. The objective of the investment package was to increase capacity and to reduce travel time with the purpose of attracting new passengers, thereby increasing the market share of public transport. A complementary objective was to improve the local environment by attracting road users to change transport mode. By definition, the project has met the capacity enhancement target. It is also obvious that this has been achieved by a cost overrun of about five percent. This seems to be close to target when comparing with experiences of other projects. The line was also opened for traffic on time. The major challenge for the ex post assessment has been to aquire information about patronage, both before the project initiation and after the operations have started. The report concludes that the type of information necessary to perform ex ante assessments of the welfare properties of a project is of the same nature as required for any follow up. This should be used as a point of departure for formulating a strategy for future information collection. It is thus reason to consider the sequence of initial information gathering, the subsequent production of an estimate of the social welfare of a project, the political decision to build, the construction phase and a subsequent follow up as parts of a continuous process of decision making and learning in order to increase the probability for that future decisions are based on the best possible material.
