In this paper we report the results of applying a new microeconomic framework to model time assignment to activities, goods consumption and mode choice jointly (Jara-Díaz and Guevara, 2003; Jara-Díaz and Guerra, 2003) that identifies the links between these decisions and permits the calculation of all the components of the subjective value of time defined in the literature: the value of time as a resource, value of assigning time to a specific activity and the value of saving time in a specific constrained activity. The samples used for the modelling come from the six-weeks travel diaries Mobidrive (Axhausen et al., 2002) and Thurgau (Axhausen et al., 2005; Löchl et al., 2005) collected in Germany and Switzerland, respectively. In this paper we present the model system that includes time assigned to activities and mode choice, a description of the data sets, a summary of the generation work of necessary variables for the modeling, the results of the calibrated models, which include the values of leisure and work for both samples, besides the values of saving and assigning travel time for the German sample, and their analysis and interpretation. The results are appropriate if we consider that the subjective values of time obtained are coherent with what was expected, positive values of leisure and negatives values of assigning travel time.
