HSA’s primary tasks include conducting Signal Warrant Analysis, Signalized Intersection Studies, Speed Zone Studies, School Zone Studies, Corridor Analysis, and Traffic Signal Timing Analysis. In addition to operational studies, HSA assists in the management of the Traffic Operations Roadway Characteristics Inventory (RCI). Traffic Operations RCI tasks include reviewing and justifying speed zone discrepancies within the RCI database and developing state regulatory documents for Traffic Operations features. Additionally, HSA conducts as-built plans review, design plans review, school zone inventories, and has developed a Traffic Signal Access Database used to generate the five year work program funding for the Traffic Signal Maintenance and Compensation Agreement.
In the development of recommendations for a Traffic Operations Study, we understand the necessity of communication with the public, local maintaining agencies and FDOT Traffic Operations Staff. Our primary goal is to provide a clear and concise operational recommendation supported by both State and Federal standards using manuals such as the FHWA Traffic Signal Timing Manual, the FDOT Traffic Engineering Manual, the FDOT Manual on Uniform Traffic Studies (MUTS), and the Manual on Uniform Traffic Control Devices (MUTCD). HSA uses a variety of operational analysis tools including the use of National Cooperative Highway Research Program (NCHRP) reports, Synchro Analysis and SimTraffic Models, SIRDA software for roundabout screenings and analysis, and highly trained professional engineers with decades of experience to develop quality engineering recommendations.
HSA has developed high resolution video monitoring systems and video processing software specifically engineered for Traffic Operational Studies. Quickly and safely deployed in self contained weatherproof cases, these camera systems allow HSA to collect high volumes of data at numerous locations simultaneously, processing the data using both manual and automated vehicle counting software. The small size and long recording times allow us to conduct spy speed studies without influencing traffic patterns, long term turning movement counts, video intersection delay studies, and queue and cycle length analysis. HSA also utilizes handheld microwave radar systems for traditional spot speed studies and pneumatic counters for traffic volume and classification counts.
With an FAA certified Drone Pilot and DJI Phantom 3 Professional Drone which utilizes 4K Video and has the capability to generate orthorectified aerial imagery, HSA can now commercially fly small unmanned aerial systems (UAS) for a variety of projects. This equipment can be used in the creation of Condition Diagrams accurately reflecting the existing conditions of an intersection or roadway. The FAA maximum 400-foot flight ceiling can also provide an excellent birds-eye overview of traffic patterns for use in a Corridor Analysis.
The ability to quickly collect high quality data enables us to conduct a precise analysis and determine the optimum traffic operational recommendations.
