Cargo Securing Design Criterion

The integrity of a cargo securing design is a function of acceleration/deceleration assumed in the design criterion.

Cargo Securing Designs are evaluated to determine if they will meet a standard that is based on acceleration/deceleration ( rate of change of velocity ) this is the criterion for evaluation.  At any given velocity a distance can be calculated within which a vehicle would have to travel during deceleration or acceleration such that if that distance was not allowed for during the deceleration/acceleration that is applied to the load would it exceed the Design Criterion used in the evaluation of the design.

If you are traveling at 50 mph a complete vehicle package would require a minimum distance for deceleration to stop that would cause the deceleration applied to be less than the design criterion.

With that in mind a transporter would set up a transport safe operating plan that would insure that the required distance be open ahead of the vehicle at all times. The lower the traveling speed the shorter the distance. At 50 mph you would need at least 337 feet to stop the vehicle and have no more than ½ G applied to the vehicle.  It is hard to appreciate the effect ½ G.

At 25 mph you need 85 feet  to stay below the ½ G requirement. If you are walking at 3 mph and you stop in 1.5 feet you experience over ½ G. Consider letting your car roll and then jumping on the breaks. Probably ½ G all because of the short stopping distance.

The issue of deceleration and the chosen criterion used to evaluate the capacity of the cargo securing design is significant in mitigating transportation risk. There are criterion for each transport process.
