In technical terms, this assumption is referred to as the "temporal transferability" of the models.

This paper summarizes the findings from a literature review that demonstrates there is little evidence about the transferability of mode-destination models over typical forecasting horizons.

To provide further insights and evidence, models of commuter mode-destination choice been developed from household interview data collected across the Greater Toronto and Hamilton Area in 1986, 1996, 2001, and 2006. This paper is concerned with the application of disaggregate models to obtain predictions of aggregate travel flows required for transportation systems analysis and planning.In this context prediction is the final step in a sequence of activities which include model development, estimation and prediction (Figure 1).Transport planning relies extensively on forecasts of traveler behavior over horizons of 20 years and more. 13th International Conference on Travel Behaviour Research, Toronto. Implicit in such forecasts is the assumption that travelers’ tastes, as represented by the behavioral model parameters, are constant over time.

The paper emphasizes that Tobit models perform better than regression or discrete choice models in estimating nontravelers.
