High Injury Network

Vision Zero is an international movement to eliminate traffic deaths. Streets on the High Injury Network (HIN) have disproportionately high rates of traffic deaths and serious injuries. DOTI prioritizes these streets for targeted safety improvements. In 2023, DOTI revised the methodology for placing streets on the HIN. Using Esri’s High Injury Network Locator in the Traffic Crash Analysis Toolbox to analyze crash data from 2016-2021, the Vision Zero team broke Denver’s most dangerous streets into two tiers. Together, Tier 1 and Tier 2 streets account for 56% of all crashes. This update keeps all streets from the original HIN, adds 21 new roadway miles, and provides a two tiered ranking to prioritize investments in safety infrastructure.零愿景（Vision Zero）是一项旨在消除道路交通死亡事故的国际行动。高伤害路网（High Injury Network, HIN）上的道路，其道路交通死亡与重伤事故发生率畸高。DOTI将此类道路列为针对性安全改造的优先实施对象。2023年，DOTI修订了道路纳入高伤害路网的评选方法。本次修订借助交通碰撞事故分析工具箱（Traffic Crash Analysis Toolbox）中的Esri高伤害路网定位工具，对2016至2021年的碰撞事故数据开展分析，由零愿景团队将丹佛市的高危道路划分为两个等级。一级与二级道路累计覆盖了全市56%的碰撞事故。本次更新保留了原高伤害路网的全部道路，新增21英里道路里程，并通过双等级排序机制，为安全基础设施的投资优先级提供明确依据。
