<DIV STYLE="text-align:Left;"><DIV><DIV><P STYLE="margin:0 0 0 0;"><SPAN>The SPIS score is determined by a weighted calculation based on summarized crashes over 3 years and traffic volume within 1/10 mile around intersections that have a Washington County jurisdiction road involved. The score is a total score considering frequency, rate, and severity. This is a 50% list of all SPIS-eligible intersections after the calculation was run. A SPIS eligible intersection either has 1) 3 or more crashes OR 2) 1 or more fatal crashes, over the 3 year period. The traffic volume is calculated based on the most recent traffic count data (from Washington County and other jurisdictions) of the 3 year crash data (i.e. the crash data is from 2014-2016 so the traffic volumes are from 2016 traffic counts).</SPAN></P><P STYLE="margin:0 0 0 0;"><SPAN /></P><P STYLE="margin:0 0 0 0;"><SPAN>See the SPIS score field metadata definition for the full SPIS calculation equation.</SPAN></P><P STYLE="margin:0 0 0 0;"><SPAN /></P><P STYLE="margin:0 0 0 0;"><SPAN>There is a model builder model within the following folder that outlines and details most of the process: \\emcgis\NAS\GISDATA\Workgroups\GISEngineering\Traffic\SPIS\2014_2016\model</SPAN></P></DIV></DIV></DIV> |
