Resumen de Commuters' valuation of travel time variability in Barcelona
The value given by commuters to the variability of travel times is empirically analysed using stated preference data from Barcelona (Spain). Respondents are asked to choose between alternatives that differ in terms of cost, average travel time, variability of travel times and departure time. Different specifications of a scheduling choice model are used to measure the influence of various socioeconomic characteristics. Our results show that travel time variability is valued 2.4 times more than travel time savings. Heterogeneity among commuters, both in terms of restrictions about the starting work time and the use of the trip to undertake other activities, are shown to have significant effects on the value of travel time variability.
