Abstract： The two-child policy will result in a growing number of school-age children and the change of family structures, which makes urban residents' travel behaviors and family decisions more complicated. This paper analyzes the characteristics of future children school-bound traveling behavior in two-child families based on RP and SP investigation. By adopting the structural modeling concept, the paper develops a school-bound traveling behavior model with families as decision-making units to study the commuting decisions making. The results show that parents' key decision making factors on picking-up and droppingoff of school-bound children are the age and safety awareness of the children, distance to school, road traffic safety conditions, and conveniences of public transit. Based on the investigation and modeling results, the paper proposes policies on urban planning, transportation system development, optimization of schoolbound traveling and reduction on urban traffic demand.
