DVRPC-GISSidewalk coverage percentages along road segments by combining road network data from Overture Maps (2025) with pedestrian infrastructure (2020) The sw_ratio field provides a normalized metric for sidewalk coverage: Calculation: Average of both side coverage ratios: (side1_length/seg_length + side2_length/seg_length) / 2 Range: 0.0 (no sidewalk) to 1.0 (complete coverage on both sides) Capped: Values are capped at 1.0 even if measured sidewalk lengths exceed segment length due to measurement overlaps See https://github.com/dvrpc/gis-sw-coverage for detailed methodologyArcGIS FeatureLayerhttps://hub.arcgis.com/datasets/bc4cbbe4f99046629a94c9e98cca1188_0engDelaware Valley Regional Planning Commission (DVRPC)PublicPedestrian Network Coverage Ratio [Pennsylvania]Web servicesPennsylvaniaLast Modified: 2025-12-18
