A disaggregated gravity model
Gitlesen, Jens Petter; Jörnsten, Kurt (Discussion paper, Working paper, 2000)The gravity model is used to estimate trip distributions. The estimates are in form of trip frequencies. This study is devoted to an entropy problem where the solution decomposes trip frequencies to the underlying probability ... -
An empirically based implementation and evaluation of a network model for commuting flows
Gitlesen, Jens Petter; Kleppe, Gisle; Thorsen, Inge; Ubøe, Jan (Discussion paper, Working paper, 2006)In this paper we present empirical results based on a network model for commuting flows. The model is a modified version of a construction introduced in Thorsen et al. (1999). Journeys-to-work are determined by distance ... -
Misspecifications due to aggregation of data in models for journeys-to-work
Gitlesen, Jens Petter; Thorsen, Inge; Ubøe, Jan (Discussion paper, Working paper, 2004-10)In this paper we develop a new simulation procedure that can be used to examine validity of model extensions. Our testing regime is carried out on a number of different trip distribution models. We test the models on ...
