Flow chart of the time activity model (a) Map of seven distinct clusters identified based on temporal information contained in the isopleths. (b) Scatterplot of the visitation rate (over 12h) vs the duration of visit (average points per visit). The dashed black line indicates the threshold in the duration of visit that discriminates between static locations from directional movement. (c) Map of time-use metrics during the participation week. The colour scale indicates the total minutes spent in each location while the size of the points corresponds to the number of visits. (d) Final classification of static locations into three microenvironments (“home”, “work”, “other”) and in movement based on spatiotemporal behavioural patterns of the individual. (e and f) Subclassifications of “other” visited microenvironments derived from GIS information and behavioural patterns
