Abstract:

In order to study the internal mechanism of decision-making process for children escort behavior influenced by families' commuter activities. This paper takes families as a unit to build activities-based twodimensional space-time trip chain analysis tool by using the first-hand data of Kunming residents travel diary survey. It dissects spatial characteristics of children accompany travel and typical transfer mode, on the bases of activity theory and time geography. Commuter constraints degree is defined to qualify the degree of parents commuting activities’space constraints and interaction. A structural equation model is established. The result shows that when commute strength of both parents are equivalent which has a strong mutual restriction, they will choose the on-the way mode first and then determine transfer person, transfer mode is determined in the end. When parents commute constraints are uneven, escort become preferential consideration of family activities, and leisure parent will be chosen to shuttle children before transfer mode determined.
