This study aimed at indexing crash worthiness capability of 20 most frequently used car brands in Iran. Since rollover crashes are one of the most important crash types due to their high impact on crash severity, they were chosen as the case study of the current research. In this regard, the data of 42,118 rollover crashes of urban and rural roads of Iran which occurred from 2009 to 2012 was us...

This paper summarizes the use of surrogate head forms in biomechanical research pertaining to head injury and, more specifically, mild traumatic brain injury. Because cadavers are limited and controlled studies of brain injury using live human subjects would be unethical, surrogate head forms are used to study the response of the human head to impact. Different head forms have been developed an...

Obtaining proper occupant restraint fit when using a wheelchair as a motor vehicle seat is often difficult to attain with vehicle-mounted restraint systems. The comprehensive evaluation conducted in this study illustrates the occupant crash protection benefits of wheelchair-integrated restraint systems, as compared to vehicle-mounted restraint systems. Using computer crash simulation, occupant ...

In this paper, the design and development of the Delphi Driver Protection Module (DDPM) using a systems and virtual engineering approach is presented. LS-DYNA software tool was used in virtual prototype studies. The DDPM consists of driver side energy absorbing components. The components included in this module are 1) an adaptive Energy Absorbing (EA) steering column, 2) driver air bag, 3) stee...

On March 19, 1997, the National Highway Traffic Safety Administration (NHTSA) published a Final Rule amending FMVSS No. 208 to allow manufacturers to de-power air bags in their passenger vehicles. This is considered an interim solution to the problems associated with aggressive air bag deployments. Consequently, the amended rule has a sunset provision that removes the amendment, with the additi...

Motor vehicle crashes remain a leading cause of injury and death in adolescents, with teen drivers three times more likely to be in a fatal crash when compared to adults. One potential contributing risk factor is the ongoing development of executive functioning with maturation of the frontal lobe through adolescence and into early adulthood. Atypical development resulting in poor or impaired ex...

Advanced Automated Crash Notification (AACN) algorithms use telemetric data from vehicles to notify emergency services of a collision involving the vehicle. The aim is to quickly dispatch the appropriate medical response to the crash scene. An important part of AACN systems is predicting occupant injury, which is highly dependent on the side of the vehicle that is struck in a crash. A given fro...

The objective of the study was to perform a benefits analysis of an injury-based advanced automatic crash notification (AACN) algorithm to estimate the reduction in undertriage (UT) and overtriage (OT) rates if the algorithm was implemented nationwide. In addition, the study sought to estimate the savings in societal costs using the Harm metric score. Benefits of an existing AACN algorithm were...

With the introduction of the FMVSS 208 upgrade for U.S. frontal crash safety, many new requirements were added. In order to meet these new requirements, manufacturers had to develop new methodologies for sensing, controlling, and deploying airbags. The standard achievement method is to use dual stage airbags with two firing thresholds. The objective of this research was to improve three key are...
