Key Takeaways
  • A traffic-control plan should communicate need, priority, path, and response time consistently.
  • Color, pattern, shape, and placement work as a system rather than as isolated decorations.
  • Retroreflectivity and wet-weather visibility are operational design concerns.
  • Final device dimensions, warrants, and placement must follow the authority having jurisdiction.
