"Procedures, measures, and applications: The aims of this poster are, a) to describe procedures for administering behaviour mapping (BM) in a variety of urban sites at different scales serving a range of populations, b) to introduce measures and analysis using GIS coding, c) discuss applications of results to urban design practice and land use policy for public health.An unexploited, powerful tool: There is surprising lack of recent literature related to behaviour mapping as it provides a powerful tool for measuring patterns of actual use of an urban site (user types, activity types, location, etc.), compared to cost and amount of space occupied. Children's Environments Quarterly 1(4), 1984/85 contained several early behavior mapping studies at neighborhood scale, including the first using a computerized relational database by Joost van Andel. GIS now enables multiple, effortless manipulations of BM data to analyse multiple aspects of actual site use in all types of urban space.An objective measure: Because data are gathered by direct observation, BM provides an excellent objective measure of actual use of a site, described as a set of calibrated behavior settings and related activity types. BM may also be applied to individual behavior by "tracking" movement through a site, analysed using The Observer analytical software package (Noldus). Tracking also enables analysis of affordances connecting behavior to specific features of environments.Intra- and Inter-site analyses: BM data can be used within and between sites to understand built environment-behaviour patterns and thus to evaluate the effectiveness of different design solutions or financial investment in different site treatments. BM also can establish use patterns by social characteristic (age, ethnic background, etc.), activity types (stationary, moving, solo, group, etc.), activity levels (sedentary, moderate, vigorous, etc.) by behaviour setting type. Measures include use/space ratio (USR), gender ratio, and setting density.Multiple applications: Poster will show examples of BM applied to a variety of different sites, including: a) "new urbanism" neighborhood design; b) community park post-occupancy evaluation (POE); c) urban museum behavior setting design and outdoor early science learning; and, d) preschool outdoor behaviour setting design and physical activity."
