Signal Intersections

Traffic control devices are signs, signals, roadway markings, and other devices located along highways and streets to provide for the secure and well-organized movement of all road transport users. These devices are located in key locations to direct and normalize traffic movement, control vehicle speeds, and caution of potentially dangerous conditions. Traffic control devices also offer significant information to users regarding detours and traffic delays. Traffic control devices at and in advance of intersections are of exacting significance.
