Do people consider an acceptable travel time? Evidence from Berkeley, CA
Abstract: This paper explores the extent to which people identify an acceptable
travel time for each trip they want to make and investigates the primary
characteristics of this behavioural threshold. We assume that an
acceptable travel time is defined through utilitarian processes that are
related to cognitive and affective evaluations of travel that develop
throughout a person’s lifetime. We apply a mixed methods approach to
explore our hypothesis, based on semi-structured in-depth interviews
with a stratified, according to commuting mode, random sample of 20
individuals living in Berkeley, CA. Our results support the validity of
the acceptable travel time concept and offer (a) initial evidence on its
variation to the travel mode and sociodemographic characteristics and
(b) insights into people’s perceptions, attitudes, feelings and
experiences about their travel. Thus, our results can contribute to a
better understanding of individuals’ travel decisions and valuation of
travel time and can inform time–space and accessibility research.
