NW 13th St & NW 23rd Ave
Grade F. About 29 crashes a year, 1.7× 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
This signalized intersection ranks 19 citywide with 132 crashes recorded since 2022 under dataGNV screening, exhibiting 12 excess crashes per year above predicted values. In FDOT records from 2015-2018, left-turn collisions were identified as the distinctive crash pattern across the intersection. The evidence points to left-turn movements as a primary area of concern even though dedicated turn lanes exist on all four intersection legs. Implementing appropriate yellow change intervals and reviewing left-turn signal phasing are recommended to address these crash trends and enhance overall intersection safety.
Left-turn. During the 2015-2018 (FDOT) period, the intersection recorded 23 left-turn crashes compared to 15 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.
