The value(s) of travel time savings considering in-vehicle activities.

Abstract

In this note I present a theoretical formulation that incorporates the main elements behind the performance of work or leisure activities while travelling, obtaining an expanded interpretation of the values of time in terms of the role played by the values of work and leisure inside the vehicle. We conclude that the value of in-vehicle time is expected to decrease as the conditions to perform those activities inside the vehicle improve. The framework admits the possibility of negative travel time values if there are leisure activities that can only be performed while traveling and are preferred over those that can be done elsewhere.
