  2. BEST MoveS • Built Environment Space-Time MOVEment Study • Associations between objective measures of movement and built environment • Movement • Transportation modes • Trip, Stop, and Dwell characteristics • Built environment • Residential & employment densities • Utilitarian destinations 2 of 4

  3. BEST MoveS Data Collection • activity & location collected with MSP • hourly survey collected with MyExperience tool running on Windows Mobile phone 3 of 4

  4. BEST MoveS Sample • 1 week per subject • waking hours (4-10 h/d dep. on battery life) • 50 subjects in UW convenience sample 4 of 4
