A Statewide Observational Assessment of the Pedestrian and Bicycling Environment in Hawaii, 2010
There were 6 possible ways to select the adjoining street segments to ensure maximum variability across our sample. One segment was chosen randomly using GIS ( Environmental Systems Research Institute, Inc, Redlands, California ). The 2 adjoining segments were then selected and could include perpendicular segments on either the left or right hand side of the road, continuous segments following straight along the road, or any combination of these.
