Name: IDOT Safety Tiers Intersections - Statewide

Display Field: PeerGroupName

Type: Feature Layer

Geometry Type: esriGeometryPoint

Description: The Illinois Department of Transportation (IDOT) conducted a safety tier analysis for the state system, and assigned the safety road index (SRI) for roadway segments and intersections. The safety tier categorizes roadway segments and intersections into different SRIs based on their potential for safety improvements, providing a rating for relative comparison.
