• Abstract:
  The Illinois data system includes the following basic files: Accident data, Roadlog File, Bridge (Structures) File, RR Grade Crossing File. The first two of these files are currently being captured in the HSIS. Raw file data are provided to the Highway Safety Research Center where they are retained as backup information. The documentation (variable listings, definitions, etc.) for these raw files and for the SAS files that are developed from them is available at FHWA offices. The conversion programs developed by HSRC and LENDIS to convert the files into SQL and SAS formats are included in the Programmer’s Guidebook, which is available at the HSIS offices at FHWA.
