A “random traffic floor” typically refers to a floor slab designed for areas with non-uniform or unpredictable wheel traffic patterns. This term is often used in the context of industrial, commercial, or warehouse floors, where vehicles like forklifts, pallet jacks, or carts move anywhere they want. This is opposed to a “defined traffic floor” where vehicles are confined to specific defined routes by physical or electronic means.
Key Characteristics of a Random Traffic Floor:
- Tested using ASTM-E1155(M), TR-34FM or various Gap Under Straightedge standards such as DIN-18202.
- Flatness and Levelness: May have more forgiving tolerances than defined-traffic floors, but still must meet performance specs for the intended vehicle type, and if it is specified with the F-Number system defined in ASTM-E1155, a Ff of 80 or higher is considered “superflat”
Contrast With Defined Traffic Floors:
- Defined traffic floors: Used in places where vehicles follow a defined path.Examples: Wire-guided trucks, rail-guided trucks, pre-programmed robot trucks.
- Random traffic floors: Used where the truck can move anywhere on the surface that is not obstructed by racks, pallets, etc.Examples: loading dock areas, turnarounds, wide bay aisles, human-operated/guided trucks, and some machine learning controlled robotic trucks.
