Methodology

How this corridor profile is produced

No applied canonical mapping exists for I-405 yet, so this profile temporarily uses the legacy curated alias matcher against the officer-recorded primary-road label. The reporting window is 2025-07-02 through 2026-07-01. Source records come from the California Highway Patrol California Crash Reporting System.

Limitations

What the numbers cannot establish

  • Raw crash counts do not measure individual risk or identify the “most dangerous” segment.
  • Traffic volume, vehicle miles traveled, road length, construction, and enforcement exposure are not controlled here.
  • Road and city labels can be incomplete, inconsistent, or revised after publication.
