Hello, everyone
I am going to use hot spot toolbox in ArcGIS 9.2 to analysis and locate the high collision location. I list the step what I did. Then I struck inside.
1. Spatial join point (collision data) and polyline (Street Network), get collision count for each segment.
2. Calculate collision rate according to segment legth and traffic volume and count of collision.
3. Already use Moran's I index to judge collision point is spatial cluster, then I choose the appropriate distance band.
4. Using Hot Spot toolbox, and choose collision rate to be an input field.But I didn't get the statisfy result.
Anyone can help me out of my struggle.
Thanks
