Using Vehicle Dynamics Simulation and Surrogate Models to Understand Factors and Mechanisms Affecting Rollover

This project investigates the feasibility of developing surrogate model for rollover crashes using vehicle dynamics simulations. Rollover crashes are still represented highly in terms of frequency and fatalities among other crash category. Although there are many vehicular technical innovations that act as a preventative or protective improvement, rollover crashes and subsequent loss of life and injuries are still highly represented in crash statistics. According to National Automotive Sampling System (NASS) Crashworthiness Data System (CDS), “A rollover is defined as any vehicle rotation of 90 degrees or more about any true longitudinal or lateral axis”. Many studies investigated the rollover causation through crash data analyses using available crash databases. The vast wealth of research on rollover as it relates to highway safety is basically derived from crash data analyses. Exceptions are for roadside safety devices (such as barriers, crash cushions…etc.) that are physically crash tested and thus will not be used if the vehicle rolled over during the crash test. However, limited studies investigated the initiating mechanisms contributing to vehicular propensity to rollover. Hence there is still a gap in knowledge to understand initiation factors (plus the causation factors) that affect rollover events and thus provide enhancement to our understanding of roadway, vehicular and human factors affecting rollover events. The objectives of the proposed research are to: (1) enhance understanding of rollover scenarios giving certain roadway designs, vehicles types and maneuvers; (2) use vehicle dynamics simulations (and not crash data) to create several vehicle rollover crashes; (3) develop a surrogate model of vehicle roll angle as a function of the factors to be study in the project; and (4) present this model as a methodology for enhanced guidance on designing roadsides for safety.
