High Injury Network

The most severe crashes are concentrated along certain corridors. The Vision Zero approach is to focus safety eff orts on these
corridors to make the greatest possible impact on severe crash rates. To identify the High Injury Network (HIN), a crash severity score was calculated for each functionally classified intersection and corridor based on the Highway Safety Manual’s Equivalent Property Damage Only (EPDO) Average Crash Frequency method.

This method considers the FDOT crash costs for each severity level (i.e., property damage, possible injury, non-incapacitating injury, incapacitating injury, and fatal crash) with a focus on severe injury and fatal crashes only. Locations with a higher severity score are experiencing more severe crashes, based on the FDOT crash costs. In considering all modes, the High Injury Network accounts for 62% of all fatal crashes and 25% of all severe injury crashes. From 2017 to 2021, 243 fatal crashes and 498 severe injury crashes occurred on these roads and intersections.
