The National Highway System supports our economy, safety, and daily travel. But delays that are caused by planned activities, like work zones and events, or unexpected problems, like crashes and bad weather, interrupt its function. Both transportation workers and travelers need accurate, up-to-date information, but this can be hard to get due to: I

Despite the widespread use of basic digital tools, many transportation projects still face delays and data gaps throughout the planning, development, and maintenance process. The current paper and PDF-based workflows require staff to manually re-enter the same information into multiple systems. This increases the risk of errors and slows down proje

Nighttime work zones create extra challenges for transportation agencies, highway workers, and drivers. As agencies shift more work (construction, maintenance, utility) to nighttime to reduce daytime delays, and with more highway workers on the job than in previous years, safety risks for nighttime crews have increased. In 2023, approximately half

After the success of EDC-5, which led to drone use in all 50 States, the focus is now on improving how these tools are used. New features include remote docking, better work zone lighting, and more accurate performance to help transportation assets, like bridges and roads, last longer and perform more reliably. Many transportation agencies face ong

Highway designers in the United States often do not have reliable information about what lies underground where projects are planned. Unexpected conflicts during construction are one of the leading causes of delays and cost overruns. Subsurface Utility Engineering (SUE) helps solve this problem by using engineering, surveying, and underground-detec
