PETRA — An Activity-based Approach to Travel Demand Analysis

  • Mogens Fosgerau
Part of the Advances in Spatial Science book series (ADVSPATIAL)


This paper concerns the PETRA model developed by COWI in a project funded by the Danish Ministry of Transport, the Danish Transport Council and the Danish Energy Research Program. The model provides an alternative approach to activity based travel demand analysis that excludes the time dimension. The approach may be thought of as an extension of the trip based frequency model and allows the model to deal with chains of tours and to treat the choice of activities as endogenous.
