This analysis identified the sidewalk coverage of each OSM street centerline across the region.For each street centerline, a PostGIS query applied the following logic:1. Select all non-crosswalk segments from the sidewalk layer that intersect a 25-meter (82’)buffer around the centerline2. Refine the selection to include sidewalks that either:a. have an intersection length greater than 25 meters,4 orb. are less than or equal to 25 meters in total length 53. Sum the lengths of the intersections of the remaining selected sidewalks4. Divide the result of Step 3 by the length of the centerlineThe result of Step 4 is a ratio where:• 1 = full sidewalks on both sides of the street• 0.5 = sidewalk on one side of the street• 0 = no sidewalks on either side of the streetFor more details of the analysis, please visit https://dvrpc.github.io/network-routing
