<br />FHWA Rule 940. Next, we will identify the locations of traffic signals and ITS devices (i.e., CCTV, ADMS, MVDS, Bluetooth, and CAV, etc.) to make sure they satisfy the design requirements of the latest version of FDOT Design Manual (FDM), FDOT Plan Preparation Manual (PPM), FDOT TEC, Miami-Dade County standards and specifications, and AASHTO Green Book. We will pay special attention to the utility conflicts and right-of-way (ROW) restrictions to ensure the new traffic/ITS installations have utility and ROW clearances. Power is critical to the functioning of ITS devices. We will also prepare the power design and voltage drop analysis report to ensure that the design of conductors, transformers, groundings, and disconnects complies with the requirements of the NEC, FDOT Construction Specifications, and the Power Company (i.e., FPL).
<br />The Corradino Team has a complete understanding of the Miami-Dade County DTPW standards, specifications, and Qualified Product List (QPL). We have reviewed hundreds of traffic signals and ITS design plans. Most recently, we reviewed the deployment plans for the new type 2070 controllers and BlueTOAD devices at 300 and 60 locations, respectively, in Miami-Dade County’s Traffic Signal Modernization Project. We are also aware of special requirements, such as the grounding requirements for video detection cameras and the minimum number of cameras based on the number of approaching lanes, including bike lanes. Corradino has led the ITS expansion across Metro Nashville, including the deployment of ATMs at numerous local agencies in Tennessee.
<br />| TRAFFIC SAFETY
<br />The City of Sunny Isles Beach’s goal is to complete projects that reduce existing or future risks or address safety hazards or needs. This goal aligns with the previously mentioned goals, as it addresses pedestrian and cyclist safety. Recently, the City has constructed complete streets projects that have improved pedestrian and bicycle safety where hazards previously existed. Corradino has expertise in evaluating high-accident/crash locations and has used Signal Four Analytics to assess these locations for other municipal clients, including the City of Cooper City, the City of Doral, the Town of Cutler Bay, and the Village of Key Biscayne. Signal Four Analytics is a program developed by the University of Florida that evaluates crash data from the Florida Department of Highway Safety and Motor Vehicles. Crash Data is updated nightly and is geo-located, allowing it to be shown on an interactive map and presented as a spatial distribution of crashes. Using Signal Four Analytics, intersection and road segment crash data can be analyzed for specific timeframes to evaluate crash types (vehicle/bike/pedestrian), time of day, road conditions, and other variables. Signal Four
<br />Analytics is a critical tool for synthesizing crash data and evaluating citywide assessments to identify potential safety improvements. This can serve as an impetus for future Capital Improvement projects. The heat map in this exhibit shows the locations of crashes that occurred over the past 12 months in the City. There were 503 total crashes observed, with 69 injuries and 0 fatalities. A similar map/list can be generated for pedestrian- and bicycle-related crashes only, allowing for a drill-down into safety issues for the most vulnerable road users. Signal Four Analytics can isolate the number of crashes involving pedestrians and bicyclists, including how many were fatal. Signal Four Analytics indicates there have been 0 fatal crashes involving pedestrians and bicyclists out of 29 total crashes in the past 12 months. This data enables an in-depth review of crash type versus crash severity to assess whether specific crash patterns can inform effective countermeasures. The key to successfully starting and completing a systemic safety analysis is a clear, specific understanding of the agency’s priorities, goals, and expectations for the process. The first issue to be resolved clearly and concisely is the availability of high-quality crash, traffic, roadway, and environmental data. While crash data and traffic count data are often readily available, a systemic safety analysis program can also benefit from detailed inventories of roadway infrastructure changes over the analysis years, as well as databases and the locations of signage, safety equipment, and traffic control devices. The more data that is available, the greater the resulting detail in crash-
