Mixed Multinomial Logit Model of Household Interactions in Daily in-Home and Out-of-Home Maintenance Activity Participation and Social Behavior (11-3518)
The main objective of this study is to empirically investigate household interactions in daily in-home and out-of-home maintenance activity participation and social interactions (measured by with whom the activities are performed). This was based on two-day activity and travel diary data from Cairo, Egypt. The proposed modelling approach entails the modelling of the following two dimensions: (1) the solo and joint in-home as well as out-of-home maintenance activity participations, and (2) the solo and joint “with whom” out-of-home maintenance activity participations. In order to achieve the study objective, two mixed logit models were developed. The proposed modelling framework is distinguished from previous related studies in several capabilities. First, it accommodates heterogeneity in responsiveness to solo and joint “with whom” maintenance activity participation. Therefore, intra-individual variations in joint activity participation could be accommodated. Second, it could determine the possible sources of any solo and joint preference heterogeneity that may exist. Third, the model is capable to capture correlations due to shared unobservable factors among solo and joint activity participation. Empirical evidences support many of our hypotheses regarding joint “with whom” maintenance activity participations. Household traditions, social roles, and lifestyle were found to be the main factors which affect joint travel participation.
