Beginning 2016, as part of the effort to modernize NHTSA’s data collection system, NCSA designed two new national probability-based crash sampling systems – the Crash Report Sampling System – to replace the National Automotive Sampling System General Estimates System (NASS/GES) and the Crash Investigation Sampling System (CISS) to replace the NASS Crashworthiness Data System (CDS). CRSS was designed completely independent of GES or CISS. CRSS has the same scope as GES : all police reported motor vehicle crashes that occur on a trafficway. The source of the information for CRSS continues solely to be the police crash report (PAR). The CRSS police crash report sample is selected in multiple stages to produce a nationally representative probability sample since nationwide direct selection is infeasible. (Author/publisher)
