Abstract
This paper describes a study of the value of in-vehicle travel time in Barcelona, Spain. In the study, values of time were established by considering the behaviour of drivers making a tradeoff between money and time when selecting a route for a trip by car. Disaggregate revealed preference observations were collected and used to estimate the coefficients in a logit model representing this behaviour. The variation in the value of time was considered for several dimensions, such as length of journey and driver income. It was found to be most appropriate to split the value according to whether the trip is made on a weekday or during the weekend, with values of 40.0 and 67.1 pesetas-1989/minute per vehicle, respectively, for these two categories.
