Research and Innovation Division
About Us / Contacts
UDOT’s Research and Innovation division mobilizes research studies and employee ingenuity to help drive continuous Department evolution.
Our Research team partners with UDOT experts, Utah universities, and consultants to identify transportation research that meets UDOT’s most important needs. They prioritize these needs in an annual workshop hosted by the division. They manage research projects, promote implementation, share research results, coordinate with national research organizations, field-evaluate products, and provide information services.
Our Innovation team gathers and supports employee ideas, and tracks them through a development process with the goal of implementing the best ideas across UDOT. They head an Innovation Council whose Stewards lead grassroots innovation efforts in their own regions and areas. They also compile the most successful ideas in our annual Innovation and Efficiencies Report which is shared with Utah legislators and the public.
Together with our partners, UDOT’s Research and Innovation division helps keep Utah moving.

September 2022: NEW RESEARCH PROJECT MANAGER
Brad Loveless is our new Research Project Manager. Brad started his career with UDOT in 2006 as a Rotational Engineer after graduating from the University of Utah. He spent 1½ years as a Roadway Design Engineer before transferring to the UDOT Willard Construction Crew where he served for over 9 years as a Field Engineer and 2½ years as a Resident Engineer. During his time in construction he has had the opportunity to work on project teams for a variety of projects including using digital delivery.
Outside of work, Brad enjoys spending time traveling with his wife and 3 sons, and is always looking for an opportunity for new experiences. Some of his favorite places that his wanderlust has taken him include the Redwoods, Lava Tubes National Monument, and the Florida Everglades.
His top five Clifton Strengths are Deliberative, Analytical, Discipline, Responsibility, and Harmony.

RESEARCH PROGRAM
UDOT's Research Prioritization Process (Annual Research Workshop)
UDOT’s annual research prioritization process matches up today’s toughest transportation challenges with the best problem solvers available to develop implementation-ready solutions. Whether you have an intractable transportation-related challenge, or are part of a talented problem-solving team, the process is here to help fuel tomorrow’s innovative transportation solutions today!
UDOT’s Research & Innovation Division spearheads this process by holding an annual research prioritization workshop each spring (also known as “UTRAC”) to help determine how the Department allocates a portion of state planning and research funds allotted to each state via 23 U.S.C. 505(a).
Workshop process participants include professionals from UDOT, FHWA, local governments, MPOs, transit agencies, universities, and the private sector. These technical stakeholders help to shape a leaner, smarter, and safer transportation network in alignment with UDOT’s Strategic Direction.
The 2024 workshop was held in person on April 15-18, 2024 for only invited UDOT/UTA evaluation teams and problem statement champions to discuss and prioritize research needs. Other changes to the workshop process this year include a simplified problem statement form, no problem statement presentations, and an exchange of written Q&A between evaluation teams and problem statement champions/authors prior to the workshop. For more information, see the updated links below or contact UTRAC@utah.gov.
UTRAC TRAILBLAZER AWARD
The Trailblazer Award is given annually during the Research Workshop to a UDOT employee or to one of our academic or consulting research partners who has a significant history of collaboration with UDOT Research and has made notable contributions toward excellence in the field of transportation research.
