    The Successes, Limitations, and Future of
    Automatic Emergency Braking Systems
    - 2hr Zoom w/ David Kidd

    DATE: Friday, 11 April 2025
    TIME: 12 noon - 2 pm EDT (GMT-4)
    COST: Free for NAPARS members;  $6 for non-members
    ACTAR: This event has been approved by ACTAR for 2 CEUs. Accredited attendees should be prepared to sign in with i-Attend app during the presentation.

    All attendees will be able to request an attendance certificate during the show.

    SUMMARY:

    We will have Dr. David Kidd, Senior research scientist at the Insurance Institute for Highway Safety (IIHS) to discuss AEB systems.

    Topics:

    • Almost every new private passenger vehicle is equipped with automatic emergency braking (AEB) which cuts the rate of rear-end crashes by around half.
    • Most private auto owners leave AEB on despite concerns about false crash warnings and braking.
    • AEB is still a nascent technology that is not foolproof. For example, it is not as effective at preventing crashes with large trucks, motorcycles, or vulnerable road users at night, and may not necessarily interact smoothly with automation.
    • Consumer information organizations, like the Insurance Institute for Highway Safety, and new regulation continue to push improvements to AEB technology, so what will AEB look like in the future?

    Our Speaker: 

    David Kidd is a senior research scientist at the Insurance Institute for Highway Safety. Dr. Kidd is a recognized leader in applied research and vehicle safety whose work focuses on identifying data-driven, pragmatic solutions for preventing harm from crashes. He has developed multiple consumer safety information programs at IIHS and authored over 40 peer-reviewed papers on topics such as seat belt use, distracted driving, advanced driver assistance systems, and driving automation technology. Dr. Kidd received a doctorate from George Mason University in 2011.


    Some of Dr. Kidd's recent publications include:

    Characteristics of automatic emergency braking responses in passenger vehicles evaluated in the IIHS front crash prevention program, David G. Kidd, Daniel Perez-Rapela, Jessica S. Jermakian, Accident Analysis & Prevention
    Volume 190, September 2023

    The Effectiveness of Forward Collision Warning Systems in Detecting Real-World Passenger and Non-passenger Vehicles Relative to a Surrogate Vehicle Target,  David Kidd, Benoit Anctil, Dominique Charlebois, SAE Paper 2024-01-1978, 04/08/2024

    We are pleased to announce Heavy Vehicle EDR training of 2025 hosted by NAPARS:

    Heavy Vehicle Event Data Recorder (HVEDR) Use in Traffic Crash Investigation Analyst Training, by Forensic Training Group (https://forensictraininggroup.com/)

    This 2.5-day starts with a refresher of definitions, supported vehicles and recent updates to OEMs. Progression into damaged vehicles, supplying power to a partial system, off-vehicle imaging considerations and predictive mentality are discussed. The bread and butter of the course talks about digital data from Advanced Driver-Assistance Systems from Wabco OnLane/OnGuard, Bendix Wingman Fusion, and Detroit Assurance. Other data sources such as dash cameras, electronic logs and fleet tracking systems are also included. The final pieces of this training opportunity included digital data from trailers and transmissions and how they may be of relevance to semi-truck collision investigations. This class offers a half day of practical testing with collision mitigation system(s).

    Heavy Vehicle Forensic Mechanical Inspection for Collision Investigators

    Instructor: Bill Foche

      Obtain the skills required to properly investigate, document, and analyze traffic crashes involving commercial motor vehicles. Collisions involving heavy vehicles often encompass unique documentation and analysis components. In this five-day course, crash investigation students learn to inspect collision-damaged heavy vehicles and gain additional skills for examining commercial vehicle crashes. This is a hands-on, basic investigation course for proper examination, documentation, and evidence preservation with no prerequisites. Curriculum includes lecture and hands-on training with collision-damaged trucks. Forensic work is conducted on the braking systems, suspension systems, wheel systems, and steering systems. Our expert instructors provide foundational information about each component, and students learn to use that knowledge to mechanically examine and test a damaged heavy vehicle. Participants complete this course able to restore a damaged air-braking system on a heavy-duty commercial vehicle to pre-collision condition in order to collect data for calculations used in evaluating the braking efficiency of a heavy-duty commercial vehicle. Students also will be able to identify parts and pieces of steering and suspension systems and explain how the components may have factored into a crash.
