Districtwide Traffic Operations Studies Contract

In preparation of the studies, tasks involved field reviews, crash analysis, collision diagrams, level of service analysis (using traffic engineering software such as Synchro, HCS, SIDRA, and VISSIM), and all types of traffic data collection (such as machine counts, turning movement counts, delay data, gap data, pedestrian/bicycle counts, speed data, ball bank studies, and queue data). 

As part of the subject contract, CTS performed numerous traffic operations and safety studies, which included qualitative assessments, signal warrant analysis, intersection/arterial analysis, left-turn phase warrant analysis, sight distance evaluations, lighting analysis, safe curve speed studies, before/after evaluations, road safety audits, Intersection Control Evaluation (ICE) studies, bottleneck mitigation studies, mid-block pedestrian crossing evaluations, access management evaluations, conceptual improvement sketches, and preliminary cost estimates.

These studies were typically conducted in response to citizen requests and other agency requests. Some examples of completed assignments include access management evaluations for SR-823 and SR-909; signal warrant analysis for SR-90/SW 147 Avenue and SR-5/NE 18 Street intersections; mid-block pedestrian crosswalk evaluation in City of Key West; road safety audits for SR-112 and SR-907; bottleneck mitigation studies for SR-90/SW 74 Avenue and SR-90/ SW 137 Avenue intersections; lighting evaluations for Shark Key and SR-112; speed limit evaluations for A1A, SR-990, and Village of Miami Shores; and wrong-way signage/pavement marking assessments for I-75 and SR-856.
