The Planned Railway Line Between
Copenhagen And Ringsted By Use Of A
Decision Support System Named COSIMA-DSS

Abstract
This paper presents an appraisal study concerning the extension of the main
railway line between Copenhagen and Ringsted by use of a software system
named COSIMA-DSS. The modelling system is based upon a
multi-methodological approach combining a cost-benefit analysis together with a
multi-criteria analysis. One of the key impacts in cost-benefit analyses is the time
benefit which depends on the timetabling. The paper describes some of the
challenges related to the calculation of the time benefits and how the time
benefits can be implemented in the decision support system. At the end of the
paper, results from the calculations using COSIMA-DSS are presented and
discussed on the basis of a newly developed Danish manual on transport
appraisal.
Keywords: timetabling, queuing time, value of time, Decision Support System,
cost-benefit analysis.
1 Introduction
Due to congestion it has been planned to increase the capacity of the main line
between Copenhagen and Ringsted since the beginning of the 1990s. There are
two different strategies to deal with the increase of traffic between Copenhagen
and Ringsted, i.e. two more tracks along the existing railway line and a new
railway line with a new layout cf. figure 1.
Keywords
timetabling, queuing time, value of time, Decision Support System,
cost-benefit analysis.
