The nature of trip making by focusing on the factors which closely represent the microscopic environment in which daily activity and travel evolve, is examined. The analysis uses the lifecycle concept as such a factor. Underlying this is the conjecture that stages in lifecycle are strongly correlated with the needs and desires for out of home activities. They are also believed to reflect the constraints imposed on activity participation and time allocation decisions. The variables frequently used to define lifecycle stages, age of the individuals, marital status, and the composition of the household, are also believed to determine largely what the household members require and desire to do. The sex and employment of the individual are known to affect strongly the allocation of activities within the household. The changes in travel patterns over the time periods considered in this study are very much a result of the significant social and cultural changes that took place in the past 20 years.
