In-Depth Analysis of Crash Causation Factors Using SHRP2 (Multiple Year Project)

Principal Investigator: Thomas Seacrist, MBE

Utilizing data from the Strategic Highway Research Program 2 (SHRP2) Naturalistic Driving Study, this study will quantify the behavioral, environmental, and experiential factors contributing to rear-end striking crashes among teen, young adult, and older drivers. The long-term objective is to inform the development of driver-specific Advanced Driver Assistance Systems that account for the unique errors exhibited by these risky driving groups.

Can the Startle Reflex be Manipulated to Reduce Take-over Time in Pre-crash Scenarios for Autonomous Driving?

Principal Investigator: Valentina Graci, PhD

This project examines if take-over reaction time to reach and turn the steering wheel during a simulated vehicle swerving is decreased by an acoustic startling pre-stimulus, i.e., a loud sound preceding the swerving event. Using a lateral oscillating sled device, two populations (adults vs. teens) will be studied and the role of driver awareness will be quantified by examining scenarios when the driver is ready to react and when the driver is involved…

Sensitivity Analysis on Factors that Influence Head Responses of Hybrid III 6-Year-Old ATD

Principal Investigator: Yun Seok Kang, PhD

This study aims to provide information that will allow child restraint system and vehicle engineers to understand the influence of neck cable tightness and repeated tests on responses of the Hybrid III 6-year-old anthropomorphic test device (ATD) head and neck in frontal impact scenarios, utilizing a controlled mini-sled system.

Biomechanics in Autonomous Vehicles: A Pilot Study to Explore Responses of Pediatric Occupants in Non-traditional Seating Conditions

Principal Investigator: Jalaj Maheshwari, MS

Autonomous vehicle seating designs have non-traditional seating positions, which potentially give rise to new impact conditions. Using computational modeling, this study explores the implications of non-normative seating conditions on booster seat-restrained pediatric occupants in simulated high-speed rear impacts.

Effectiveness of Boosters vs. Forward-facing Five-point Harness

Principal Investigator: Julie Mansfield, PhD

As the optimal time to transition a child from a forward-facing child restraint system to a booster is not currently clear, this study aims to help inform better guidelines for children during this transition. Statistical analyses will be conducted on cases in federally available databases and the mechanisms of injury in each type of seat will be analyzed to compile recommendations for industry interventions.

Effects of Adjacent Seat Positions on CRS Performance in Side Impacts

Principal Investigator: Julie Mansfield, PhD

Versatility in vehicle seating positions offer consumers the ability to adapt the vehicle environment to their family’s needs. However, it is currently not known how these various seat configurations and obstacles might interact with child restraint systems (CRS) in adjacent seats during side impacts. This study utilizes sled testing to define the performance outcomes of CRS in side impacts under specific seating configurations.

Understanding Child Restraint System Use on Airplanes

Principal Investigator: Aimee Palumbo, PhD, MPH

This study aims to identify strengths and critical gaps in flight attendant and parents’ knowledge and perceptions that lead to low child restraint system use for child airline passengers. Following surveys administered to both flight attendants and caregivers, analyses will estimate rates of CRS use and identify key themes and recommendations.

How Do Novel Seat Positions Impact Usability of Child Restraints?

Principal Investigator: Patrice Tremoulet, PhD

Autonomous driving technology offers manufacturers the opportunity to design vehicles with different interiors than traditional automobiles. It is important to consider the safety implications when contemplating different interior design possibilities, particularly for families with young children who will need to use child restraint systems. This study explores how having seats in non-traditional orientations within a vehicle may impact parents’…

Child Seats with Load Legs: Understanding the Response of the ATD in Mitigating Head Injury Risk Across Crash Directions

Principal Investigator: Aditya Belwadi, PhD

This study aims to quantify the response of the instrumented anthropomorphic test device (ATD) in rear-facing child seats with and without load legs in simulated frontal, oblique, and lateral impact crashes. The broad long-term objective of this line of research is to gain insight into ATD kinematics and kinetics as a function of the child seat.
