TRAVEL BUDGETS - A REVIEW OF EVIDENCE AND MODELLING IMPLICATIONS

This paper reviews the empirical data that has been put forward as evidence for the feasibility of direct forecasts of the average amounts of time and money allocated to travel, and the alternative model frameworks which have been designed to exploit such forecasts. It is concluded that the evidence for the stability of aggregate travel behaviour from analyses of cross-sectional data has not yet been reconciled with the variations shown over time. At an individual level, there are large, and apparently random, variations in the amounts of travel undertaken in a day. The hypothesis that an overall "budget mechanism" governs individual travel decisions is discussed; it is concluded that this hypothesis remains unproven, but raises interesting questions about current methods of forecasting travel demand.
