Project Name (Name as to appear on plaque): US 98 at Trilby Road / CR 575 Roundabout

FDOT FM#:254646-1-52-01 Project Description (150 characters): This US 98 at Trilby Road Roundabout project was initiated in response to severe angle & left turn crashes & focused on Vision Zero Safety Solutions.

Project Narrative (500 char.): This project provided a unique design solution that ensured speed reduction to provide a safer facility for all road users. ELEMENT completed the survey and design on an accelerated design process so HSIP funds could be used for construction. We coordinated with project stakeholders, provided iterative design solutions to meet the design guidelines, avoided right of way impacts, and expedited the design services and utility coordination to deliver the final design in 10 months.

F. Detailed Project Information (Address all applicable award criteria):(750 characters max for each item)

1. Complexity of Project: US 98 at Trilby Road/CR 575 was a rural, high-speed, stop-controlled intersection with a posted speed of 55 MPH. Video count data had to be acquired at the project intersection to determine the specific design control vehicles to be used on this key freight corridor with 22 percent truck traffic. A 9-phase TTC plan was developed that maintained access to local businesses and residences, complied with the restriction of no full road closures of US 98, and maintained the truck traffic through the corridor.

2. Scheduling Challenges: Survey and design were completed within an accelerated 10-month schedule to meet an established letting date so available Highway Safety Improvement Program (HSIP) funds could be used for construction. Right of way acquisition would have extended the project duration by two or three years.

3. Innovative Technical Concepts: Understanding the high-speed nature of the corridor, the project incorporated a pilot effort related to maintenance of traffic that evaluated varying combinations of active work zone awareness devices (AWADs), dynamic speed feedback signs (DSFS), and law enforcement to reduce motorist speed in order to provide a safe facility for all users during construction. The study results from this effort have been taken and developed as best practices for speed management on other construction projects throughout the state.

4. Cost savings: The implementation of the roundabout is anticipated to have an overall savings to society of $28.9 million through eliminated crashes. The roundabout is expected to yield an 83 percent reduction in all crash types.

5. Public Involvement/Support: Throughout the design process, ELEMENT actively coordinated with key project stakeholders, including Pasco County, elected officials, and FDOT staff. They have all applauded the completed project and immediate enhancement to safety, both at the intersection and in the surrounding area, due to the reduced operating speeds along the corridor.

6. Minimization of Negative Impacts: From 2012 to 2017, there was a total of 37 crashes that resulted in three fatalities. A unique design solution was required to ensure speed reduction to provide a safer facility for all users. After iterative design solutions that would avoid right of way impacts, a roundabout was identified as the most effective solution. The roundabout is expected to reduce the overall crashes at the intersection by 83 percent, resulting in a significant savings to society. A 9-phase temporary traffic control plan was developed to maintain access to local businesses and residences, comply with the restriction of no full road closures of US 98, as well as maintain the high truck traffic through the corridor.

7. Partnering: Throughout the design process, ELEMENT actively coordinated with key project stakeholders, including Pasco County, elected officials, and FDOT staff. In addition, throughout construction, close coordination with the contractor resulted in the delivery of the project ahead of schedule.

8. Functionality of Project: As one of the first intersections in the region evaluated utilizing the Department's Intersection Control Evaluation process, this intersection will serve as validation of roundabouts as an effective countermeasure on high-speed facilities with over 20 percent truck traffic.

9. Aesthetics: The roundabout provides enhanced aesthetics through the use of colored pavement, lighting, and landscaping. The landscaping and lighting also serve as visual cues for vehicles as they approach the roundabout.

10. Environmental Impacts/Benefits: The minimization of right of way reduced the overall footprint of the project resulting in less disturbance of the existing landscape. The use of the roundabout allowed for landscaping to be installed which will help provide cleaner air. The new roadway lighting used LED fixtures that use friendly backlight, uplight and glare technology that reduce light pollution with more focused roadway lighting and help with "Dark Skies". LEDs have a lower energy consumption than other light fixtures and contribute the least amount of carbon dioxide into the atmosphere.

11. Sustainability: The implementation of the roundabout is anticipated to have an overall savings to society of $28.9 million through eliminated crashes. Additionally, the roundabout was designed to accommodate pedestrian and bicycle facilities as additional right of way is acquired.

12. Cost Overruns and Time Extensions: The project was completed under budget and ahead of schedule. The budgeted cost of construction was $2,778,535. The actual cost was over $50,000 under budget. The scheduled construction completion date was October 10, 2020. The project was delivered four days ahead of schedule. The survey and design were completed within the 10-month accelerated schedule.

13. Technical/Engineering Challenges Overcome: Design challenges for this accelerated schedule included limited right of way, roadway speed, adjacent land uses, and the high volume of trucks on the corridor. Design solutions had to ensure the geometry in advance of the roundabout achieved the

required speed reductions. Designs had to limit right of way impacts while providing a design that allowed for future pedestrian and bicycle facilities, as additional right of way is acquired. The TCP Plan had to accommodate the project construction while maintaining access to local businesses and residences, complying with the restriction of no full road closures of US 98, and maintaining the truck traffic through the corridor.

14. Safety Improvements: An 83 percent reduction in all crash types is anticipated with an overallsavings to society of $28.9 million. Additionally, the roundabout was designed to accommodatepedestrian and bicycle facilities, as additional right of way is acquired. The LED fixtures provide higherColor Rendition Index that allows more constrast in color from reflected surfaces allowing road usersto see better with less light intensity.
