Project Overview
CFX began the capacity improvements of the southern corridor of SR 417 from four to six lanes (three lanes in each direction) to improve traffic flow on one of CFX’s busiest expressways. The project is also adding wider median shoulders that can temporarily accommodate additional traffic during emergency response events, such as traffic accidents or hurricane evacuations. Several noise walls will also be built along the corridor.

Project Leadership and Scope

Members of our team served as the ITS Engineer of Record for three projects within this initiative, covering extensive enhancements to the expressway’s Intelligent Transportation Systems (ITS). Collectively, these three projects spanned over 16 miles of SR 417 from International Drive to Boggy Creek Road.

Design Features and Innovations

Our team led the design, which included:

• Part-time shoulder use and variable speed limit signage on SR 417

• Installation of over 125 miles of fiber optic and electrical cabling

• Deployment of dozens of CCTV cameras, vehicle detectors, and over 200 dynamic message signs

• Design of power services for all ITS systems

As part-time shoulder use and variable speed limit signage were new to the Central Florida Expressway Authority (CFX), Members of our team collaborated closely with CFX representatives to develop custom installation details, which were later adopted as system-wide standards.

Power System Design Expertise

The power system design included:

• Sizing uninterruptible power supplies (UPS)

• Conducting voltage drop and conductor sizing calculations

• Performing load flow assessments, fault current calculations, and arc flash hazard assessments

• Developing Python software to perform electrical load calculations and UPS sizing

• Creating detailed electrical models using SKM PowerTools for ITS and lighting power services

These efforts ensured robust and reliable power systems to support the expanded ITS infrastructure, enhancing traffic management and safety along the corridor.
