Question 1

Q1: Are summary measures of BE characteristics of locations in the entire space-time realm of activity associated with overall levels of self-reported PA? Are summary measures of BE for the entire space-time realm of activity more strongly associated with PA than home-based summary measures of BE?

• PA = f(BE, PC)
  • PA = MET-minutes/week spent in walking, based on International Physical Activity Questionnaire
  • BE = a vector of overall summary built environment measures, measures from SmartMaps
    • Residential density
    • Street or intersection density
    •  % park
    • Length of trail in bandwidth
    • Grocery store/supermarket
    • Other destinations: pubs, traditional restaurants, convenience stores
    • Transit ridership
    • Traffic volume (from PSRC/EMME2)
    • Land use mix (composition and configuration), by focal processing in Fragstats
      • Index of Juxtaposition & Interspersion (IJI)
      • Aggregation Index (AI)
      • Shannon Diversity Index (SHDI)
  • PC = a vector of personal characteristic measures (covariates)
