The Knoxville Regional TPO executive board unanimously endorsed a supplemental Safe Streets and Roads for All (SS4A) safety plan May 28 that expands the regional roadway safety action plan to cover the entire Anderson County area outside the TPO planning boundary.
Jonah, the TPO presenter, told the board the supplemental planning grant totaled $30,000 from the Federal Highway Administration (FHWA), consisting of $24,000 federal funds and a $6,000 local match. The study was administered through FHWA on behalf of the Anderson County Highway Department and will be added as an appendix to the TPO regional safety plan after endorsement.
The supplemental plan covers unincorporated Anderson County and the small cities of Norris and Rocky Top and used public input via a project website and interactive safety map, two public meetings hosted by the highway department, and a crash analysis using TDOT’s AASHTOWare safety platform. Jonah said the plan used a five‑plus year crash period (2016 through September 2021) consistent with the original regional plan.
Public input and crash analysis produced recurrent themes: poor visibility and roadway signage, a need for guardrails and reflectors, speeding and lack of enforcement. The presenter said over half of serious crashes in the analyzed period occurred on roadways posted at 45 mph and that 65% of crashes on the corridors reviewed were single‑vehicle (run‑off‑road into a ditch or fixed object). The study identified 11 priority roadway segments, ranked by crash severity, public input, and equity overlays identifying disadvantaged communities; each segment entry includes primary crash types and recommended treatments.
Jonah said endorsement would allow Anderson County to apply for SS4A implementation funding under the FY25 notice, which offers planning and implementation dollars nationwide; he noted the FY25 application deadline for certain SS4A opportunities is June 26 and that implementation funding pools include substantial national dollars for projects that move forward.
The technical committee had unanimously recommended endorsement. Mayor Ron Williams moved the motion to approve and Mayor Terry Frank seconded; the board voted aye and the motion carried.
