Analysis of uncertainty in performance indicators of a complex activity-based model: The case of the Albatross model system

This paper reports the main results of an uncertainty analysis conducted for the Albatross model in the Rotterdam region. The analysis focuses on the number of runs required to achieve stable coefficients of variation for different mobility indicators and the associated confidence intervals. Results indicate that few runs are required to obtain stable results. To achieve conventional confidence intervals substantially higher numbers of runs seem required.
