Service Description: <DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>This analysis identified the sidewalk coverage of each OSM street centerline across the region.</SPAN></P><P><SPAN>For each street centerline, a PostGIS query applied the following logic:</SPAN></P><P><SPAN /></P><P><SPAN>1. Select all non-crosswalk segments from the sidewalk layer that intersect a 25-meter (82’)</SPAN></P><P><SPAN>buffer around the centerline</SPAN></P><P><SPAN /></P><P><SPAN>2. Refine the selection to include sidewalks that either:</SPAN></P><P><SPAN>a. have an intersection length greater than 25 meters,4 or</SPAN></P><P><SPAN>b. are less than or equal to 25 meters in total length 5</SPAN></P><P><SPAN /></P><P><SPAN>3. Sum the lengths of the intersections of the remaining selected sidewalks</SPAN></P><P><SPAN>4. Divide the result of Step 3 by the length of the centerline</SPAN></P><P><SPAN /></P><P><SPAN>The result of Step 4 is a ratio where:</SPAN></P><P><SPAN>• 1 = full sidewalks on both sides of the street</SPAN></P><P><SPAN>• 0.5 = sidewalk on one side of the street</SPAN></P><P><SPAN>• 0 = no sidewalks on either side of the street</SPAN></P><P><SPAN /></P><P><SPAN>For more details of the analysis, please visit </SPAN><A href="https://dvrpc.github.io/network-routing" STYLE="text-decoration:underline;"><SPAN>https://dvrpc.github.io/network-routing</SPAN></A></P></DIV></DIV></DIV>
