A highly disaggregated modal-split model -- some tests

This paper investigates the usefulness of parameter disaggregation within a logistic modal-split model. Changes in parameter values caused by different origin-location and household characteristics are compared with parameter changes due to slight alterations to the model's structure. This spatial and sectoral parameter disaggregation scheme is used to link a modal-split model with a previously developed trip-distribution model at the same level of resolution. The disaggregations are seen as offering useful insights into intraregional variations in modal choice.
