APPENDIX D: OVERALL HIN CORRIDOR LIST This appendix includes the entire list of High-Injury Network segments in West Orange based on the crash and equity analysis. The project team developed the HIN using the Safer Streets Priority tool by Toole Design Group that utilizes a sliding window analysis to develop high-injury corridors for pedestrians, bicyclists and vehicles (or other crashes). The sliding window analysis uses a 1/2 mile window and 1/10th mile increment across all corridors to identify high-injury crash concentration for each segment of roads in West Orange. The HIN score assigns a higher weight to the most severe crashes. The HIN score is calculated by multiplying the number of Fatal (K) and Incapacitating Injury (A) crashes by 3, and multiplying the number of Non-Incapacitating Injury (B) crashes by 1. Once the weights are established and applied to the crashes, the total number of crashes are aggregated along a corridor while incorporating the crash severity weighting. Possible Injury (C) crashes and Property Damage Only (O) crashes are not reflected. Separate weighted HINs were developed for each mode (pedestrian, bicycle and motor vehicle) based on different thresholds. The Pedestrian HIN includes all segments with a score of 1 or greater and covers ~17 miles or 10% of West Orange roads. The Bicyclist HIN includes all segments with a score of 1 of greater and covers ~8 miles or 5% of West Orange roads. The Vehicular HIN includes all segments with a score of 5 or greater and covers ~22 miles or 13% of West Orange roads. The combined HIN included all three of the individual-mode HINs and covers about ~34 miles or 20% of all West Orange roads. The team then developed an environmetal justice score to identify which network segments should be prioritized based on equity factors. All HIN network segments were given a composite score based on the highest average score for each factor. As noted in the report, the project team then developed the final HIN score by combining the EJ composite score and the HIN crash score.
