The Copenhagen Traffic Model and its Application in the Metro City Ring Project

Abstract In June 2007, the Danish Parliament passed an act to finance the construction of the Metro City Ring in Copenhagen. The assessment project is based on the passenger patronage forecasts for 2015 from the Copenhagen traffic model. In this paper we show how the model forecasts for this particular infrastructure project can be explained through detailed knowledge of model structure and model validation.

Car Users’ Trade-Offs Between Time, Trip Length, Cost and Road Pricing in Behavioural Models

Stated Preference (SP) experiments are the obvious choice in order to forecast travellers’ responses to alternatives that do not exist today. SP experiments can in addition change the variables in a controlled factorial design, whilst Revealed Preference surveys (RP) have to rely on measured observations. Preferences concerning correlated explanatory variables such as travel time and travel length can therefore often be estimated more easily by SP experiments than by RP surveys. However, respondents may not act as they claim in the interview and the design may affect the results.
