Creation of a rough runnability index using an affordance-based framework

Running is one of the most popular forms physical activity. To date, no literature explores association between features built environment and running. A limited amount uses walkability as a proxy for runnability, thereby misjudging differing goals walking running: leisure, sport or commute. We create rough runnability index using an affordance-based framework conceptual methodological attempt to quantify that facilitate hinder running form leisure Three indices are created in City Surrey, British Columbia, Canada pixelated edges. find areas downtown core near high traffic routes show low safety general whereas parks traffic, residential higher runners.
