• 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 3 tiers:• Tier 1: All locations Criteria 1 & 2• Tier 2: All locations with at least

one crash & Criterion 3• Tier 3: All the remaining locations

Curves with Safety Improvement Potential

High Priority Pedestrian Safety Corridor

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

All fatal and A-Injury crashes in Illinois for

2007-2011

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 2007-2011125 fatal crashes418 A-Injury crashes
