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>
