North Carolina 1997 Code book Introduction This code book documents data sets describing North Carolina motor vehicle accidents that occurred during calendar year 1997. The data sets were generated by the Transportation Data Center at the University of Michigan's Transportation Research Institute (UMTRI) from data provided by the North Carolina Department of Transportation. The cooperation of that agency is gratefully acknowledged. The data set supplied by the North Carolina Department of Transportation contains one record for each crash. This structure has been reformatted into a set of three rectangular files. The characteristics of the three system data sets that have been developed are presented in the table below. Characteristics of the North Carolina Data Sets Data Set Key Freq Variables Accident NC97ACC 231,630 1-50 Vehicle NC97VEH 426,500 1-50,101-190,201-221 Occupant NC97OCC 615,915 1-50,101-190,201-221, 301-307 The code book itself is divided into three sections that document the accident, vehicle & driver, and occupant records, respectively. The univariate frequencies and percentages displayed in each section are taken from the corresponding data set (i.e., vehicle and driver frequencies from NC97VEH, occupant frequencies from NC97OCC, etc.). An index at the end of the code book cross references words used in the code book by variable and code value number.

North Carolina 1997 Introduction While every effort has been made to provide accurate, reliable data, inconsistencies may arise from the source data or from the reformatting procedures used. Consequently, the Data Center cannot guarantee the accuracy of the data but will try to resolve any discrepancies that are found. Any comments or suggestions concerning the data or the codebook may be made by calling the Data Center at (734) 763-3230 or by emailing TDC-UMTRI@umich.edu. For more information about our full line of services, please visit our website: http://www.umtri.umich.edu/tdc/. The most current TDC codebooks are available there in PDF format and codebooks can now be ordered online. ii March 2008
