Collision avoidance systems that detect pedestrians around blind corners either do not need line of sight or are mounted at the corner itself. Ultra-wideband (UWB) and other radio tag systems measure distance around racking, so they warn a tagged pedestrian and an operator before they see each other. Fixed cameras or sensors at an intersection watch both approaches and switch a warning light or alert the truck. Truck-mounted cameras, radar and LiDAR need a direct view, so they detect a person only once the corner opens up. Tag systems protect only tagged people; fixed units protect only the places where they are installed.
The full guide is Forklift intersection safety, covering right-of-way rules and traffic controls alongside technology. OSHA 1910.178 requires operators to slow down and sound the horn where vision is obstructed; detection adds to that rule and does not replace it.
Forklift proximity detection technologies compared sets the methods side by side. During a pilot, test the worst corners in your building with a person walking out at normal pace, and record how early each side is warned.
