High-Injury Network Corridor Safety Audits

VZ Safety Audit_action shot.png

Vision Zero safety audits are conducted on Arlington’s High-Injury Network corridors. Our High-Injury Network (HIN) includes corridors in Arlington that have recently experienced concentrations of critical crashes. Arlington’s High Injury Network represents just 7% of over 555 miles of roadway in the County, but these corridors saw 78% of all serious or fatal crashes in 2017-2019. Staff are prioritizing audits on corridors where there are upcoming/ongoing projects (to assist in coordination on safety features in these projects) and on corridors adjacent to areas identified by equity data (income + race).

The purpose of the audits is to visit each High Injury Network corridor to identify:

  • Quick-build projects that we can implement quickly to improve safety,
  • Existing/upcoming projects occurring on the corridor and how they will help address safety, and
  • Other opportunities or needs to enhance safety for consideration for future capital projects or plans.

HIN safety audits are not intended to fix all safety needs immediately. Rather, they are a strategy for staff to identify safety needs that we can address quickly and safety needs that we can begin to plan to address on a larger scale.

Upcoming HIN Safety Audits

Below is the tentative timeline for safety audits of the 2023 High-Injury Network. The schedule order takes into consideration: crash severity, upcoming/ongoing site development, upcoming/ongoing capital projects, recently implemented projects, and coordination with nearby plans or studies:
