In this research, we study the correlation between life cycle stages and time allocation for the benefit of self and others. Life cycle stages are defined based on age, employment, family status, and disabilities. Time allocation is classified based on the people with whom each respondent came into contact and for whom he or she performed activities and travel. Based on a two-day time use diary, daily time allocation is classified in social fields that we define as family, friends, schoolmates, co-workers, clubmates, among others. We also include time for sleeping and activities and personal travel. The data analysis creates a taxonomy using cluster analysis of time-of-day activity sequences, complexity of time schedules, and uncovers its correlation with life cycle stages.

Since 2004, Konstadinos (Kostas) G. Goulias has been a Professor of Transportation at the Department of Geography at the University of California, Santa Barbara. From 1991 to 2004 he was Professor of Transportation in the Department of Civil and Environmental Engineering of PennState University, where he also directed research centers. His research is on large-scale transportation systems modeling and simulation, travel behavior dynamics, sustainable transportation, smart cities, economic geography, travel survey methods, geocomputation, and geoinformation. He chairs the International Association for Travel Behaviour Research and he is the co-editor-in-chief of Transportation Letters an international peer-reviewed journal published by Taylor and Francis. He received a Laurea (5 years and a thesis equivalent to M.S.) in Engineering from the University of Calabria (Italy) in 1986, an M.S. in Engineering from the University of Michigan, Ann Arbor, in 1987, and a Ph.D. in Engineering from University of California Davis, in 1991.

The objectives of the ThinkSpatial presentations are to exchange ideas about spatial perspectives in research and teaching, to broaden communication and cooperation across disciplines among faculty and graduate students, and to encourage the sharing of tools and concepts.
