UDOT demonstrates crash‑data platform and safety‑analysis tools for local agencies

A UDOT traffic‑and‑safety analyst demonstrated the department’s crash‑data platform to the TAC on April 15, showing tools that local agencies can use to identify hotspots and evaluate countermeasures.

Sianka Nan, UDOT data and safety manager, outlined three primary tools: a crash‑query function that filters by county, crash attributes (pedestrian‑ or bicycle‑involved, DUI), hour of day and severity; a network‑screening tool that ranks locations by EPDO (equivalent property‑damage‑only) to identify hotspot intersections; and a safety‑analysis module that estimates benefits from countermeasures and supports project development for UDOT and regional partners. She demonstrated drawing a circle around an intersection and reported counts by severity (for example: 71 crashes at a selected intersection, including one fatal crash and 14 injuries) and said the platform provides redacted crash narratives for fatal and serious incidents.

Nan described how the safety‑analysis tool suggests countermeasures (rumble strips, barriers, friction treatments) and said UDOT can provide access to city and county staff. "If you don't have access and if you want to explore this tool we can provide you access," she said, and dropped a link in the meeting chat to request permissions and tutorials.

UDOT staff noted narratives are redacted to remove PII and that local agencies may request help running network screening or safety analyses for specific corridors. The presentation included a brief technical glitch earlier in the meeting as staff joined and reconnected; the demonstration proceeded once the presenter resumed connection.
