Sidewalk coverage percentages along road segments by combining road network data from Overture Maps (2025) with pedestrian infrastructure (2020)<\/span><\/p>

<\/p>

The sw_ratio field provides a normalized metric for sidewalk coverage:<\/span><\/p>

Calculation: Average of both side coverage ratios: (side1_length/seg_length + side2_length/seg_length) / 2<\/span><\/p>

Range: 0.0 (no sidewalk) to 1.0 (complete coverage on both sides)<\/span><\/p>

Capped: Values are capped at 1.0 even if measured sidewalk lengths exceed segment length due to measurement overlaps<\/span><\/p>
