This paper summarizes and analyses findings from more than two dozen aggregate and
disaggregate studies of travel time (and sometimes money) expenditures, exploring the …

This paper provides a comprehensive review of travel-time budget (TTB) studies in the
literature for about the past four decades. Starting with the concept of TTBs, it discusses both …

After decades of study, the value of travel time remains incompletely understood and ripe for
further theoretical and empirical investigation. Research has revealed many regularities and …

Recent research suggests that the average time spent travelling by the Dutch population has
increased over the past decades. However, different data sources show different levels of …

The regularities in travel time and money expenditures of household and travelers in urban
areas are examined. Data from both developed and developing countries are analyzed and …

Many researchers have found the idea of a 'constant outlay'on travel a magnetic hypothesis.
If true, it would provide a useful touchstone to test the reliability of existing transport models …

This paper contests the conventional wisdom that travel is a derived demand, at least as an
absolute. Rather, we suggest that under some circumstances, travel is desired for its own …

This paper presents the results of a series of mixed logit models focusing on the distribution
of the values of travel time savings. The parametric assumptions include both normal and …

The major mobility variables from about 30 travel surveys in more than 10 countries are
compared in this paper. The analysis of cross-sectional and longitudinal data broadly …

We provide a synthesis of results and insights from the Swedish Value of Time study, with
focus on what is relevant for transport appraisal and understanding travel behavior. We …
