This analysis identified the sidewalk coverage of each OSM street centerline across the region.<\/SPAN><\/P>

For each street centerline, a PostGIS query applied the following logic:<\/SPAN><\/P>

<\/P>

1. Select all non-crosswalk segments from the sidewalk layer that intersect a 25-meter (82\u2019)<\/SPAN><\/P>

buffer around the centerline<\/SPAN><\/P>

<\/P>

2. Refine the selection to include sidewalks that either:<\/SPAN><\/P>

a. have an intersection length greater than 25 meters,4 or<\/SPAN><\/P>

b. are less than or equal to 25 meters in total length 5<\/SPAN><\/P>

<\/P>

3. Sum the lengths of the intersections of the remaining selected sidewalks<\/SPAN><\/P>

4. Divide the result of Step 3 by the length of the centerline<\/SPAN><\/P>

<\/P>

The result of Step 4 is a ratio where:<\/SPAN><\/P>

\u2022 1 = full sidewalks on both sides of the street<\/SPAN><\/P>

\u2022 0.5 = sidewalk on one side of the street<\/SPAN><\/P>

\u2022 0 = no sidewalks on either side of the street<\/SPAN><\/P>
