Crash Mapping and ARNOLD Leveraging Statewide Local Road Network Crash Mapping PROJECT SCOPE / OBJECTIVES Locate State and Off-state crashes on single map Have the ability to display multiple years of crash data Perform statewide safety analysis query functions 10 Other Uses High Risk Rural Roads (HRRR) Incident Locator Tool (ILT) Wisconsin Department of Transportation
