A high injury network (HIN) consists of mapping roadway corridors of a network and evaluating the associated number of people killed and severely injured in traffic crashes. Adoption of a HIN is recommended in Vision Zero, which is a strategy aimed at eliminating all traffic fatalities and severe injuries, while increasing safe, healthy, and equitable mobility for all road users. As part of the adoption of Vision Zero, a practical and repeatable process was developed for the city of Madison, Wisconsin. Accounting for data and resources available, the methodology consisted of network segmentation into intersections and segments, crash data collection, and evaluation of crash frequency analysis using the equivalent property damage only (EPDO). Safety levels were defined based on percentile thresholds by facility type. The results of the analysis are maps of the network with intersections, segments, and corridors—color coded according to the level of safety.
