Pre-crash safety systems are reversible systems that are deployed in a vehicle when external and internal sensors determine that a crash is likely. This paper provides a preliminary estimate of the effect of such systems in reducing the number and the severity of injuries to automobile occupants in traffic accidents. These estimates are obtained by combining test data for pre-crash system response with the statistical information on vehicle crashes available in NASS-CDS database for years 1996-2007. It is observed that significant reductions in the number and the severity of occupant injuries may be achievable by pre-crash systems that include pre-crash braking enhancements and seatbelt pre-tightening actions.

Rollover research data is a valuable resource in the field of accident reconstruction and automotive safety. This data can provide the accident reconstructionist with information regarding number of rolls versus roll distance and vehicle average deceleration during the rollover event. One source of rollover research data readily available to the general public is the National Highway Traffic Safety Administration's (NHTSA) Crash Test Database which includes dolly rollover test data. This data includes testing performed using the FMVSS 208 dolly fixture and the NHTSA Rollover Test Device (RTD) used from 1985 to 1995. The purpose of this paper is to provide a more thorough analysis of the RTD rollover tests performed for NHTSA which includes a history of the RTD test series, detailed review and analysis of the available data and videos to provide a better understanding of the actual vehicle test dynamics.

The National Automotive Sampling System (NASS) Crashworthiness Data System (CDS) contains a wealth of field accident data. As the size of the database continues to grow, the statistical significance of the data increases and trends can be observed. Numerous papers contain analysis and graphs of particular aspects of the data, but they are usually included in a supporting role to the main topic of the paper, and are extremely difficult to locate in a focused document search. The purpose of this paper is to provide an updated, comprehensive resource to reference when looking for commonly sought-after accident statistics. Charts include accident distributions by Delta-V and impact direction with corresponding injury severity rates. Rollover data is also analyzed, as well as historical trends for injury severity, belt usage, and air bag availability.
