The standard method of estimating the value of travel time variability for use in policy
appraisal is to estimate the parameters of a reduced-form utility function, where some …

This paper explores the relationships between three types of measures of the cost of travel
time variability: measures based on scheduling preferences and implicit departure time …

Many commuters across the world find their travel time between home and work to be rather
unpredictable. In addition to systematic variation by time of day and by day of the week …

This paper tackles the valuation function of travel time savings. Formally, this valuation
function is derived from a nonlinear representative utility which successfully relates …

Different assumptions about travelers' scheduling preferences yield different measures of
the cost of travel time variability. Only few forms of scheduling preferences provide non-trivial …

Current benefits from travel time savings have only been related to the benefits from
reducing mean travel time. Some previous attempts of including variability in the generalised …

This paper reviews the broad literature on the behavioral value of travel time savings.
Specific consideration is given to the economic theoretic foundations and their translation …

Over the past several years a number of research projects have attempted to empirically
measure behavioural responses to changes in travel time variability. These have generally …

This paper considers the value of travel time variability under scheduling preferences that
are defined in terms of linearly time varying utility rates associated with being at the origin …

This paper derives a measure of travel time variability for travellers equipped with
scheduling preferences defined in terms of time-varying utility rates, and who choose …
