What this tracks
This dataset shows the locations and details of impact attenuators (crash cushions) installed on Tennessee highways, interstates, and ramps.
Why it matters to you
Knowing where attenuators are placed helps you assess roadside safety on your regular routes—like spotting protective barriers before sharp curves on SR362 in Carter County. Truckers can check if ramps have crash cushions before planning heavy-load routes. Residents near high-risk intersections (like exits with frequent rear-end collisions) can advocate for new attenuators using this data when contacting TDOT.
How to read this data
ROUTE — The highway identifier (e.g., “SR362”).
LOC_DESC — Which side of the road the attenuator is on (e.g., “Left”).
FEAT_DESC — The type of attenuator (e.g., “TRACC” for trailing-arm crash cushion).
LATITUDE/LONGITUDE — Precise coordinates (e.g., 36.33197315, -82.2659414) to map locations.
