Corridor map
Priority segments are the barrier candidates: unprotected crashes only (not contained by existing barrier). The design centerline is split into curve (violet) and tangent (teal) sections; segments are highlighted by section and sized by EPDO. Radii are as-built values, shown for reference.

Priority segments
Each barrier-candidate segment with its section and, on curves, the as-built radius. Sort any column; filter by section.

Curves with recurring dry-pavement crashes
Horizontal curves with a repeat crash pattern that is mostly on dry pavement, where friction is unlikely to be the cause, whether or not barrier is present. As-built radius is shown for reference; tighter radii are the stronger candidates. Threshold: at least 3 crashes and over half on dry pavement.
