Samenvatting

The travel time factor represents the effect of travel time on trip interchanges. In its use in gravity model studies, the travel time factor is an empirical hand-down curve that is considered constant over time. This paper questions constancy over time by attempting to express travel time curves in parametric form and relating the parameters of variables within the study area that know to change over time.
