  9. GIS-Based Analysis http://s-salemrev-110/main/transgis_tutorials.htm • Useful tool for crash patterns (snow/ice crashes, lane departure crashes, etc.) • More complex analysis possible • Relationship between crashes and other data (i.e., high speed signalized intersections) Ice Sensor Dynamic Signs
