Crash Avoidance and Autonomous Vehicles Research at CIRP

Self-driving and Highly Autonomous Vehicles are widely anticipated to be the future of automotive safety. Current commercially-available vehicles are increasingly automated with Advanced Driver Assistance Systems (ADAS) including Forward Collision Warning and Lane Departure Warning, and automated features such as Automatic Emergency Braking.

The CIRP research team focuses on a particularly vulnerable population – teen drivers – and how they interact with ADAS technology when behind the wheel. As self-driving and semi-autonomous vehicles enter US roadways, CIRP researchers are also investigating new safety challenges for child passengers.

The multidisciplinary research team utilizes CIRP’s Advanced Driving Simulator, which can emulate semi-autonomous and self-driving vehicles, to study the human factors at play when transitioning from one driving mode to the next in both day-to-day driving or in an emergency situation. Data analysis of the Strategic Highway Research Program 2 (SHPR2) Naturalistic Driving Study is allowing the team to investigate 1,500 real life crashes, many of them involving teens. In addition, the research team conducts qualitative research through focus groups and national surveys to assess the knowledge and comfort level of young drivers with ADAS and automated technologies.

Areas of Crash Avoidance and Autonomous Vehicles Research

Current Crash Avoidance and Autonomous Vehicles Projects

Novice Teen vs. Experienced Adult Drivers

  • Driving Analytics: Comparison of Teen and Adult Naturalistic Car-Following Patterns -- This line of research uses the large-scale SHRP2 naturalistic driving database to compare crash rates between teen drivers ages 16 to 19 and experienced adult drivers ages 35 to 54. Scene videos were reviewed for all events to identify rear-end crashes and near-crashes, allowing the investigators to compare rear-end crash rates, crash severity, and impact velocity between novice teen drivers and experienced adult drivers. The results will help vehicle manufacturers design active safety systems to address the braking deficits of newly licensed teen drivers. Principal Investigators: Helen Loeb, PhD; Thomas Seacrist, MBE Funding: Center for Child Injury Prevention Studies (CChIPS)

  • Emergency Autonomous to Manual Takeover in Driving Simulator: Teens vs. Adult Drivers -- This study uses CIRP’s advanced driving simulator to safely introduce teen and adult drivers to driving in an autonomous vehicle and assess their ability to remain vigilant and promptly take over in the case of a failure of the autopilot. The project aims to understand how much driving experience is needed to safely take over from autopilot mode, as well as how the driver’s age influences the ability to sustain attention. This information can be used to better understand the human factors at play in self-driving technology. Principal Investigators: Helen Loeb, PhD; Aditya Belwadi, PhD Funding: Center for Child Injury Prevention Studies (CChIPS)

User Perceptions of Automated Vehicle Technology

  • Active Safety Technology and Teen Drivers: Impressions, Perceived Need, and Intervention Preferences -- This project seeks to understand how teens and parents are responding to the advent of autonomous vehicles, particularly Advanced Driver Assistance System (ADAS) technologies such as forward collision warnings, blind spot warnings, and lane keeping assist. Three teen focus groups and two parent focus groups were conducted to better understand perceptions about ADAS, if teens and parents are interested in using them, and what barriers might exist in their use. The findings of the focus groups have been used to develop a national survey being administered to 1,000 teens and 1,000 parents. Principal Investigators: Thomas Seacrist, MBE; Eve Weiss, MS Funding: Center for Child Injury Prevention Studies (CChIPS); State Farm Mutual Automobile Insurance Company
  • Ensuring Safety of Children in Self-Driving Vehicles -- This study seeks to understand the safety needs of children riding unaccompanied in self-driving vehicles. Many parents rely on services like Uber to bring their children, riding unaccompanied by a parent or caregiver, to afterschool activities or other functions. As self-driving cabs are now entering the roadways, the question about the proper age for a minor to be unaccompanied in a cab becomes more complex. This research will help inform specification of safety features, guidelines, and policies that will enable children to safely ride unaccompanied in self-driving vehicles. Principal Investigator: Patrice Tremoulet, PhD Funding: Center for Child Injury Prevention Studies (CChIPS)

Virtual Driving Assessment

  • Ohio Portable Driving Simulator Systems Study -- Using software developed and validated on CIRP’s high fidelity fixed-based driving simulator, CIRP researchers are collaborating with CHOP spin-out company Diagnostic Driving to adapt a validated virtual driving skills assessment for real-world deployment by state DMVs, beginning with implementation through the Ohio Bureau of Motor Vehicle’s licensing centers, to help reduce the high crash rate among newly-licensed drivers. Principal Investigator: Flaura Winston, MD, PhD Funding: Ohio Department of Public Safety
