Types of data coding adjustments:

Reclassification of end terminals or injury severity, based upon additional documentation submitted by partners.

Deletion, based upon arrival of additional information, such as:
subject matter experts may find that cases do not qualify because the redundant case information; or

subject matter experts may find that the damaged end terminal was not an energy absorbing design and therefore not included in this study.

Disqualification, based upon a non-passenger vehicle impact, such as farm vehicles and tractor trailers, for which the end terminals are neither designed nor
tested.
