Read the full write-up
This signalized intersection ranks 5 citywide, recording 143 crashes in dataGNV records since 2022. The crash rate per million entering vehicles exceeds the median for similar corners. In FDOT records from 2015-2018, left-turn collisions were an elevated pattern, accounting for 29 crashes where fewer were expected. The imagery shows that a dedicated left-turn lane is present on each leg, but whether left turns receive protected arrow phasing cannot be verified from imagery. Implementing appropriate yellow change intervals offers crash reduction benefits reported by FHWA, while reviewing left-turn signal phasing addresses the prominent turning collision pattern.
Left-turn. In 2015-2018 (FDOT) records, 29 left-turn crashes occurred compared to 16 expected at similar corners. The imagery shows a dedicated left-turn lane is visible on 4 of 4 legs and the intersection is signalized. The imagery shows whether left turns get a protected arrow can't be read reliably from the imagery.
