  1. Driving Zero Fatalities to a Reality: Partnering for Safety Priscilla Tobias, PE State Safety Engineer, Bureau Chief Illinois Department of Transportation

  2. ILLINOIS FATALITIES 10 year average: 1450

  3. ILLINOIS SERIOUS INJURIES

  4. What to Do?

  5. STRATEGIC HIGHWAY SAFETY PLAN

  6. Illinois SHSP

  7. County SHSP • Top 35 counties plus those within MPOs • State and Local Roadways • Aligns with the State SHSP • Identify Opportunities for Focus • Local Workshops 48.2% 46.3%

  8. County Data Trees

  9. Emphasis Area Heat Map

  10. 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

  11. 5% “High Priority Local Roadway Segments”

  12. 5% “High Priority Local Roadway Intersections”

  13. Systemwide Improvements • http://www.idot.illinois.gov/Assets/uploads/files/Transportation-System/Manuals-Guides-&-Handbooks/Safety/Systemic%20Safety%20Improvements%20Analysis,%20Guidelines%20and%20Procedures.pdf

  14. Curves with Safety Improvement Potential • Represent Approximately 10% of Severe Crashes • Represent Approximately 30% of Roadway Departure Crashes

  15. 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

  16. High Priority Pedestrian Safety Corridor • A total of 161 corridors were analyzed for Districts 1-9 • The 161 corridors had a total of 543 severe (K & A-Injury) pedestrian crashes for 2007-2011 • 125 fatal crashes • 418 A-Injury crashes

  17. Safety Data Analysis & Tools • Safety Data Portal • Crash Data • Crash Reports • Local 5% Lists • Data Trees • Heat Maps • Look for Common Crash Trends • Determine Future Needs

  18. Strategic Highway Safety Plan

  19. Partnering and Collaboration bring the best ideas and maximize the limited resources for the greatest impact.
