From early studies of time allocation onward, it has been acknowledged that the "productive" nature of an activity such as travel could affect its utility. Yet until recently, there has been very little empirical assessment of such an effect, in particular the potential effect of activities conducted while traveling on the (dis)utility of the trip and thence the value of travel time for such a trip. In previous phases of this multi-year study, the project developed a fundamental conceptualization of polychronicity (multitasking) attitudes and behavior, and created and administered a survey to measure multitasking attitudes and behavior specifically while commuting, together with general attitudes, mode-specific perceptions, and standard socioeconomic traits (N = approximately 3020 Northern California commuters). This proposed continuation of the research will fund the development of first-of-their-kind revealed preference mode choice models accounting for the impact of multitasking attitudes and behavior on the utility for various alternatives. The resulting insights will inform and improve policies and services promoting more sustainable forms of travel, and lead to more realistic models and forecasts. |
