NW 13th St & NW 16th Ave
Grade F. About 27 crashes a year, 2.1× what a similar intersection sees. Most are rear-end crashes; left-turn crashes stand out. Suggested fix: appropriate yellow change intervals.

Read the full write-up
The intersection of NW 13th St & NW 16th Ave ranks 12 citywide, recording 125 crashes since 2022 with 14 excess crashes per year. In the 2015-2018 (FDOT) period, FDOT data showed 41 left-turn crashes, representing an elevated pattern. The evidence points to left-turn movements as a significant contributing factor. The imagery shows that dedicated left-turn lanes exist on all approaches at this signalized intersection, though signal arrow phasing cannot be verified from imagery. Implementing appropriate yellow change intervals is evaluated as a primary countermeasure.
Left-turn. In the 2015-2018 (FDOT) period, left-turn crashes totaled 41 against 21 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.
