- Using four consecutive days of SITRAMP Data (2004) from the Jakarta Metropolitan Area (JMA), this study examines the interactions between individuals’ activity-travel pattern variables in the context of their daily constraints, resources and external opportunities. The results from our simultaneous equation modeling show that the observed individual’s activity-travel patterns are the result of the complex interactions between each individual’s activity-travel parameters, which vary from day to day. Some of the interactions are similar with the patterns produced by travelers from developed countries, while others are different. Household and individual characteristics are the most significant variables influencing the interactions among individual activity-travel patterns. Different groups of travelers have different trade-off mechanisms. Further analyses on the stability of the activity-travel patterns across different days are provided. Daily commuting time and regular work commitments heavily shape workers’ and students’ flexibility in arranging their travel time and out-of-home time budget, leading them to more stable daily activity-travel patterns than non-workers. The model also shows that highly unpredictable traffic significantly influences workers’ and students’ intra-personal variability in travel time, more so than any other variable.
