Analysis the Household Activity Chains Based on Utility-Maximizing Model

Most activity-based models of transport planning depend on an individual decision-making process modelling daily activity and the activity chains. The dependence on individual decision-making approaches may be partially due to the deficiency of modelling methodologies for group decision-making within the household. Therefore, in this paper, we present a study to analyse the group decision-making among the household members. This paper aims to analyse and estimate the activity allocation and the activity chains between the household members by using the mixed multinomial logit model based on the utility function. The study is using the 2014 Budapest city Travel Survey. This paper presents a model for the activity type and activity chains that household members pursue during the daily activity. The study assumes that the household members allocate their activity type and duration within the activity chains to get a high utility. Besides that, the effects of household and individual socio-demographics, travel and activity variables on the activity allocation are examined. According to the results that indicated that the activity purpose with (3.392 & 2.136) is an essential factor and positively affects the likelihood of choice among the activity types or activity chains. Finally, the implications of the results for travel behaviour and transportation planning are identified.
