A 1 km circular radius buffer around two of the schools included inthis study. Park space is represented by the green areas and thestreet network is shown with the grey lines. Panel A is an example ofa least ideal neighbourhood (e.g., highly walkable, low density ofcul-de-sacs, moderate park space) and Panel B is an example of a mostideal neighbourhood (e.g., low walkability, high density of cul-de-sacs anddead ends, low park space) for physical activity in youth.
