Intersections are locations of a significant number of conflict points and therefore, by their nature, are locations that crashes are more likely to occur. Over 1,300 intersections in the region were assessed as part of the High Crash Intersection Assessment.
High Crash Intersections were ranked based on three factors:
· Crash Frequency: The number of crashes within 250 feet of the center of the intersection
· Crash Rate: The number of crashes per million vehicles entering an intersection
· Crash Severity Index: An index that assigns higher weights to crashes that result in injuries and fatalities than to crashes that result in property damage only
The cumulative rank of these three factors became the intersection’s score. An intersection with a lower cumulative score was ranked higher on the list.
There were high crash intersection lists developed for each state. Additionally, since there were not a significant number of Bullitt or Oldham County intersections on the Kentucky list, a separate list was created for each of those counties. Maps accompany each of the lists.
