Abstract

The authors hope to provide an intermediate method of data extraction, taking advantage of the improvements in child passenger data collection and recording. The authors also wish to highlight the importance of appropriate usage of the data. As suggested in the Eigen 2007, the enhanced data set SAS files, also known as the 30-file data set, will be contrasted with the 11-file data set format, the traditionally available NASS CDS SAS files, and analysts will be referred to the NHTSA web site for supplementary information. Further, frequently asked questions will be addressed to provide uniform information dissemination to all users. The primary data source will be the National Automotive Sampling System (NASS) Crashworthiness Data System (CDS). As conclusion, the authors propose a three-step extraction methodology to be used until the enhanced data files can be released. This includes traditional data extraction to retain weighting factors, extraction of the enhanced variables, attributes, and associated graphics, and manually integrating the two data sources.
