County SHSP
  • Top 35 counties plus those within MPOs
  • State and Local Roadways
  • Aligns with the State SHSP
  • Identify Opportunities for Focus
  • Local Workshops

5 high priority locations for safety
5% “High Priority Locations” for Safety
  • 5% Locations Weighted for KAB
  • Criterion 1: Locations with 1+ KA and 3+ KAB crashes
  • Criterion 2: Locations with 1+ KA and 2+ KAB crashes
  • Criterion 3: Locations with 1+ KAB crashes
  • 100% local roadway segments were divided into 3tiers:
  • Tier 1: All locations Criteria 1 & 2
  • Tier 2: All locations with at least one crash & Criterion 3
  • Tier 3: All the remaining locations with zero crashes

High Priority Pedestrian Safety Corridor

All fatal and A-Injury crashes in Illinois for 2007-2011

D1 had different criteria than D2-9 due to the number of pedestrian fatalities and severe injuries.

  • For D1 a high priority pedestrian safety corridor was defined as a segment which had at least 3 fatal pedestrian crashes close together
  • For Districts 2-9, a pedestrian severe injury corridor was defined as a segment which had:
    • At least 2 fatal crashes close together or
    • At least 2 A-Injury crashes close together or
    • At least 1 fatal crash and 1 A-Injury crash close together
