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
17
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 High Priority Pedestrian Safety Corridor
