In this study, activity allocation is analyzed in two stages, by modeling the activity data of household individuals. In the first stage, activity participation patterns of individuals are examined for both out-of-home maintenance and discretionary activities. The influence of socio demographic, trip related, person, household role, role of constraints, and household related information are investigated in this stage using empirical data from the San Francisco Bay Area Travel Survey.

In the second stage, interactions between Internet and communications technology use, and activity and travel patterns are analyzed by developing a series of econometric models, using the Bay Area Travel Survey. These interactions are examined at three levels: (a) whether the Internet is used or not, if yes, used for what purposes, (b) what is the relation between physical and virtual activities in terms of internet use, and (c) to what extent does the Internet influence the daily trip patterns such as frequency and duration. Internet use, ICT device, predicted probabilities, socio demographic, work, and household related variables are used as explanatory variables in these models.

The results from this study are described and have important implications for congestion management, air-quality mitigation and travel demand forecasting.
