Road-departure crash concentration
Road-departure crashes per ~0.5 mi station bin, stacked by outcome (unprotected, struck existing barrier, other). Bars rise for crashes on the left of the centerline and drop for the right. Zoom and hover to trace the point on the map above; click a bar to locate it.
| Rank | Station | Crashes | Unprotected | EPDO | Severity | Most common type |
|---|
Existing barrier performance
Road-departure crashes by object struck, and serious-injury rate by shielding (placed barrier vs unprotected hazards).
Barrier candidate locations
Unprotected crashes only (the vehicle was not contained: ran off into ditch, embankment, or rollover, or struck a shieldable hazard with no barrier on that side), clustered into candidate segments and ranked by EPDO. The Existing barrier column separates new-barrier locations from existing barrier to review. See the Barrier need map view.
| Station | Side | Crashes | EPDO | Severity | Existing barrier | Hazard behind |
|---|
Rock-face assessment
Rock-face involvement is inferred from the inventory (a run-off with rock mapped behind it), since the crash code rarely names it. The Rock face map view shows mapped rock, candidate barriers, and where barrier already shields it.
| Station | Side | Crashes | EPDO | Other hazard behind |

Evidence: every road-departure crash & the object it struck
Every road-departure crash tied to the inventory. Struck object is coded from the report; the associated feature is the mapped object matched to it. Click a row to locate it.
