DANIEL CHACON ENGINEER TECHNICIAN Pedestrian Crosswalk Assessment – Collins Avenue & Poinciana Island Drive (2024) | I prepared a comprehensive technical memorandum evaluating the need for a midblock crosswalk at Collins Avenue and Poinciana Island Drive. This assessment was conducted as part of an FDOT District-Wide Traffic Operations study in response to resident concerns about pedestrian safety. I analyzed pedestrian demand, traffic patterns, and roadway conditions to determine the feasibility of a crosswalk installation. Based on my findings, I provided recommendations to enhance pedestrian protection and improve overall safety in the area. Xaviel Llerena, (305) 470-5303 Safety Assessment – SR 968/SW 1 Street from SW 17 Ave to SW 13 Ave (2024) | I conducted a technical analysis along SR 968/SW 1 Street from SW 17 Avenue to SW 13 Avenue to evaluate potential safety improvements. This study was part of an FDOT initiative in collaboration with the City of Miami Police Department under the High Visibility Enforcement (HVE) Grant. I assessed roadway conditions, lighting adequacy, and non-motorized traffic conflicts to identify hazards reported by officers. Based on my findings, I provided recommendations aimed at enhancing pedestrian and vehicular safety while improving overall corridor functionality. Xaviel Llerena, (305) 470-5303 Traffic Speed Study – Miami-Dade & Monroe Counties (2025)| I conducted traffic speed studies at seven locations across Miami-Dade and Monroe Counties as part of an FDOT District-Wide Traffic Engineering Data Collection Contract. The objective was to evaluate the need for adjusting posted speed limits based on field observations and traffic data analysis. Following FDOT’s Traffic Engineering Manual (TEM) and the Speed Zoning Manual (Section 9.3.3), I analyzed 85th percentile speeds, ten-mile pace, and compliance rates during peak and off-peak hours.
