Theoretical Consequences of Travel Time Budget

This paper presents the findings of constant travel time budget. The travel time expenditures are constant only at the most aggregate statistical level. Nevertheless, individuals’ travel time expenditures do show patterns that can be partly explained by measurable characteristics such as individual and household characteristics, attributes of activities at the destination, and characteristics of residential areas. If travel time expenditures are considered a constant at the aggregate level over time and space the transport development as service development or as vehicle improvement would lead to some questions. This paper focuses on these questions. Consequently, further research on travel time budget is justified.
