NATIONAL ACCIDENT SAMPLING SYSTEM 1994 CRASHWORTHINESS DATA SYSTEM DATA COLLECTION, CODING, AND EDITING MANUAL. 17TH EDITION

The National Accident Sampling System (NASS) consists of 24 teams of accident researchers situated throughout the country. At each Primary Sampling Unit (PSU) site the accident research team investigates a probability sample of police reported accidents involving passenger cars, light trucks, and vans which were towed, according to the police report, from the scene due to damage. This system has been termed the Crashworthiness Data System (CDS). Zone centers have been established to provide for the quality control of the CDS data collected and the technical management of the teams within their zone. The purpose of this manual is to provide PSU team members, zone centers, the Transportation Safety Institute NASS Training Program Coordinator, and the National Center for Statistics and Analysis with a consistent, standardized set of instructions for sampling accidents and collecting, coding, and editing the data. The manual is divided into the following seven sections: (1) Introduction; (2) Description of the Sampling Frame; (3) Overview of Sampling Activities; (4) Overview of Information to be Collected on Sampled CDS Accidents; (5) CDS Submission Instructions; (6) GES (General Estimates System) Quality Control and Submission Instructions; and (7) Coding Instructions. The Appendices contain some of the necessary references, including the Uniform Symbols for Scene Marking, the Uniform Symbols for Accident Diagramming, and the listing of Variable Computer Formats.
