Accessibility measures and population density were introduced in the 31 propensity regression models to account for the impact of spatial characteristics at school 32 locations and to identify the spatial distribution of behavioral patterns. Each of the 33 spatial patterns created a map combining the impact of all the significant spatial variables 34 to display patterns of behavior and intra-household interaction. These patterns are able to 35 identify, as examples, the negative impact of a park area in the middle of the City of Los 36 Angeles on children’s independent and active commute to school and the significantly 37 different intra-household interaction patterns at different locations in the region. The 38 results of this study show an opportunity to expand the microanalysis to a more 39 comprehensive treatment of travel behavior in space and to contribute to the development 40 of models integrating land use and transportation. 41 42 Number of Words = 6,178 (body) + 1,500 (4 tables and 2 figures) = 7,618 43 For consideration for presentation at the 90th annual meeting of the Transportation 44 Research Board and publication in the Transportation Research Record 45 Page 1 of 24 TRB 2011 Annual Meeting Paper revised from original submittal.
