High Injury Network

In 2022, DDOT conducted an analysis of all corridors in the District based on reported injury and fatality crash data from June of 2016 – July of 2021. The resulting corridors are mapped here as the High Injury Network (HIN). Tier 1 streets segments and corridors represent the highest priority segments citywide. The Tier 2 segments supplement Tier 1, to represent the highest priority segments and corridors for each Ward. The streets highlighted in green are streets that were evaluated in 2015, continue to see high rates of injury, and are funded in the FY2023 budget to receive safety treatments in the next few years. In service of the Mayor's Vision Zero initiative, DC Government will prioritize safety interventions on the roadways with the most deaths and injuries as our High Injury Network.
