Generally, a scope of services is set, and a list of pertinent roads and intersections is compiled. These can be as few as those immediately adjacent to a site, or as many as several miles from an individual site. The initial analysis includes roadway, transit, and bicycle-and-pedestrian levels of service. These conditions are projected over the future planning horizon, generally using appropriate traffic engineering tools. This can be done as far as 1 year out for immediate development, or as far as 25 years out for a long-range transportation plan. The future year system performance without the project is measured against the future year systems with the project or projects. <br />Deficiencies must be mitigated. Each mitigation method is tested until the system performs favorably. For individual transportation projects, at least three alternatives are tested, including a “no build” scenario. These alternatives are evaluated as to their impact on the environment, community profile, economic development, and transportation level of service in the community. Intensive public involvement is typically held, and ultimately, a locally preferred alternative is selected. Often, when federal funding is sought, these processes can be highly competitive, and individual benefits must be advocated for strenuously. As explained in the ITE Traffic Engineering Handbook 7th Edition, “traffic engineering studies are used to obtain relevant empirical data, and that data must be collected in an unbiased, objective manner to result in appropriate decisions for improvements.” As the City initiates projects, these traffic <br />engineering studies can be used to explore alternatives, conduct operational analysis, evaluate system/network performance, etc. Corradino staff have been involved in various types and sizes of traffic engineering studies, ranging from single-intersection turn-lane analyses to corridor operational analyses to statewide roadway safety audits. No matter the size or type of study, Corradino will provide the necessary technical expertise to collect data, analyze/evaluate alternatives, provide recommendations, and, if needed, implement a solution. <br />| TRAFFIC SIGNAL TIMING <br />A traffic signal timing project can be as small as one intersection or as large as an entire City’s traffic signal system. Over the past couple of years, the South Florida Region has deployed adaptive signal control technology (ATSC) in numerous municipalities. However, several other corridors around South Florida continue to experience changes in travel patterns and increased volumes, both of which could necessitate updated traffic signal timing and coordination. <br />Corradino will follow this process for a typical corridor-type signal timing project: <br />• Data Collection – existing timing data; traffic counts; field inventories• Evaluation of Existing Conditions using the Synchro model• Timing Plan Development – number of plans; system boundaries; cycle length; TOD schedule; yellow-red clearances; split; offset; phase sequence; coding sheets• Field Implementation and Fine-Tuning• Before and After Study <br />Corradino staff have completed numerous signal timing projects for various agencies. Our staff knows their way around the traffic signal cabinet and traffic signal controllers. They can take on any traffic signal timing project and complete all tasks from data collection through controller programming and final reporting/presentations.
