Traffic Engineering
Traffic engineering is the backbone of a safe, efficient, and reliable transportation system. It involves planning, designing, building, and managing the features that help people travel safely — whether they’re driving through a roundabout, navigating a construction zone, or depending on clear signage to reach their destination.
NDOT's traffic engineering team thoughtfully designs intersections, road layouts, signals, and signage to keep traffic flowing smoothly and reduce the risk of crashes — but it doesn’t stop when the concrete dries. Traffic engineering also includes setting up and managing work zones to protect both workers and drivers during construction and maintenance projects, as well as the ongoing upkeep that keeps our roads safe year-round. This means maintaining and replacing signs, updating guardrails and lighting, mowing roadsides for visibility, and ensuring drainage systems work properly to prevent hazards.
