Arlington conducts an in-person safety audit for each High-Injury Network corridor over the course of the three-year HIN cycle. The audits include staff across teams and disciplines to visit each corridor and identify:
HIN safety audits are not intended to fix all safety needs immediately. Rather, they are a strategy for staff to identify key safety needs and plan out improvements both in the short, intermediate, and long term.
We publish a follow up review of each HIN corridor about three years following the safety audit to ensure that all action items are complete and to check for any continued or new crash patterns.
Below are the initial safety audit documents and applicable progress updates organized by HIN audit cycle
