Notes: Spearman rank correlation coefficients. † p < 0.10, * p < 0.05, ** p < 0.01, *** p < 0.001. Model-detected features were assessed by z-scoring the average count of positive feature instances for coordinates within a 500 m street network buffer around participants’ homes. Perceived neighborhood features were assessed by the Neighborhood Environment Walkability Scale (NEWS). All crosswalks = sum of zebra and line crosswalks. Total microscale score = sum of z-score averages for bike symbols, all crosswalks, curb cuts, walk signals, sidewalks, sidewalk buffers, and streetlights within each participant’s 500 m neighborhood buffer.
