The Changes of Transportation Demand Behavior for Children and Teenagers Using a Cohort Method

Transportation demand behavior of children and teenagers are influenced by the composite and complex factors such as social, school, and family norms as well as the physical and psycho- status developments of this stage and, as a result, this earlier stage of life have produced the unique characteristicsof transportation demand behavior because of their individual limitations in this young age. These complex characteristics of transportation behavior are also different from those of adults and are overlooked by the government over a long period.

Therefore, it is necessary to conduct research on the transportation demand behavior of the group of age under 18 from the perspective of the evolution of the stage development and cohort differences. We intend to employed a consecutive three-year longitudinal deign, which follows the method of the cohort study, to catch the dynamic behavior changes within the study period. It is anticipated that the results of this study would focus on the determinants such as social, school, and family factors, as well as individual development in association with the evolution of transportation mode choice and risk concepts of this young age group.
