Abstract:
Comparing the 1988-2007 files with files from years prior to 1988 is not recommended. The

principal attributes of the NASS CDS 1988-2007 files include: focusing on crashes involving

automobiles and automobile derivatives, light trucks and vans with gross vehicle weight less

than 10,000 pounds (4,537 kg); giving special consideration to late model year vehicles (the five

most recent model years [four, beginning in 1996]); emphasizing the more serious injury

crashes; eliminating the pedestrian and non-motorist record, the driver record and vehicle

registration information. A revised set of data collection forms was designed in 1988 for the

crashworthiness data system. Some features are: the introduction of an Accident Event Record

to capture all events in the crash; the creation of three new vehicle records (General Vehicle,

Exterior Vehicle, Interior Vehicle); and the separation of occupant records into an Occupant

Assessment Record and an Occupant Injury Record, wherein all injuries are coded.

The NASS CDS file is available in two automated formats: a sequential data set or a Statistical

Analysis System (SAS) data set. Hard copy data collection records, sanitized to protect privacy,

are available for review through data collection year 1996. An electronic version of these

records is available beginning with data collection year 1997. These records contain

photographic images, scene diagrams, and vehicle damage diagrams.

This manual and the NASS 2007 Crashworthiness Data System's Data Collection, Coding and

Editing Manual are the primary documentation supporting the automated file. When using this

file one should be careful to understand the coding conventions of all variables used thoroughly.
