I list the step what I did. Then I struck inside. </SPAN><BR /><SPAN>1. Spatial join point (collision data) and polyline (Street Network), get collision count for each segment.</SPAN><BR /><SPAN>2. Calculate collision rate according to segment legth and traffic volume and count of collision.</SPAN><BR /><SPAN>3. Already use Moran's I index to judge collision point is spatial cluster, then I choose the appropriate distance band.</SPAN><BR /><SPAN>4. Using Hot Spot toolbox, and choose collision rate to be an input field.But I didn't get the statisfy result.</SPAN><BR /><BR /><SPAN>Anyone can help me out of my struggle.</SPAN><BR /><BR /><SPAN>Thanks</SPAN></BODY></HTML> Tue, 13 Dec 2011 21:28:44 GMT weipan 2011-12-13T21:28:44Z Collision data hot spot analysis https://community.esri.com/t5/transportation-questions/collision-data-hot-spot-analysis/m-p/342333#M1116 <HTML><HEAD></HEAD><BODY><SPAN>Hello, everyone</SPAN><BR /><BR /><SPAN>I am going to use hot spot toolbox in ArcGIS 9.2 to analysis and locate the high collision location.
