Beyond the Last Precrash Speed Value – Wade Bartlett

WHEN: 05 Dec 2025 12:00 – 14:00 (EST) Location Worldwide via Zoom Spaces left 1400 Beyond the Last Precrash Speed Value DATE: Friday, 05 December 2025
TIME: 12 noon – 2pm EST (GMT-5, or 9am-11am Pacific Time)
COST: Free for NAPARS members; $6 for non-members
ACTAR: This event will be submitted to ACTAR for CEU consideration. All attendees will be able to request an attendance certificate during the show. The show will be recorded and put in the Reference Library along with various supporting materials. ABSTRACT: Crash investigators often open an EDR report, look at the last speed value recorded, and say, “That’s the speed at impact.” And while it _might_ be true, one can be terribly mistaken. Also, failing to examine the rest of the report leaves a ton of information on the table – yaw rate, steering angle, brake fluid pressure, wheel speeds, and actual precrash acceleration, for instance. This session will explore extracting that data from a report and using it to understand the whole event. We will discuss the mechanisms of traction and steering that manifest in the sensor data.     

A little history
     -Where is speed data coming from?
     -Making tabular data useful
     -Vehicle Dynamics and Friction
     -Newer = more sensors & more data = opportunity to answer lots of questions:
     -What is the driver doing with the controls?
     -What is the car commanding?
     -What is the chassis experiencing?
    -Confirming data with multiple sensors.

SPEAKER: Wade Bartlett has over 30 years of experience in all aspects of crash reconstruction, focusing heavily on friction, motorcycles, and EDRs. He is a licensed Professional Engineer in NH, holds ACTAR #789, and has been a part-time police officer in NH since 2003. He occasionally teaches for IPTM. He is the administrator of NAPARS.

Hydroplaning – Alan Moore

WHEN: 16 Jan 2026 12:00 – 14:00 (EST) Location Worldwide via Zoom

DATE: Friday, 16 January 2026
TIME: 12 noon – 2pm EST (GMT-5, or 9am-11am Pacific Time)
COST: Free for NAPARS members; $6 for non-members
ACTAR: This event has been submitted for ACTAR CEU consideration.

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

The presentation will be recorded and put in the Reference Library along with any supporting material.

TOPICS TO BE DISCUSSED:

==> Traditional derivation of hydroplaning – aircraft, tire pressure, locked wheel skid

==> Application to road vehicles – tire size, tread depth, surface macrotexture, water film thickness

==> Modern testing of wet tire performance

==> Wet tire characteristics – pneumatic trail and hydrodynamic drag

==> Comparison of hydroplane testing and theory to hydroplane case studies (Daytona, Oscoda, LA)

==> Application of hydroplaning theory in accident reconstruction

OUR SPEAKER: 

Alan Moore is one of our favorite guests. He is a mechanical engineer and principal of A.B.Moore Forensic Engineering. (https://www.abmoore.com/home.html)

He specializes in vehicle accident reconstruction, vehicle design analysis, and mechanical engineering consulting. 

Mr. Moore holds a Bachelor of Science in Mechanical Engineering from Michigan State University and a Masters degree in Business Administration from the University of Florida. He is a licensed Professional Engineer, a Board Certified Forensic Engineer, and an ACTAR-certified accident reconstructionist. His past experience includes two decades of accident reconstruction and automotive engineering.

He previously worked at Ford Motor Company as a design engineer on the Ford Expedition and Excursion. Mr. Moore also serves as a high-performance driving coach for aspiring race car drivers through the Porsche Club of America. 

Some Hydroplaning references to freshen up with before the show:

Start with Frank Navin’s SAE paper 950138, “Hydroplaning and Accident Reconstruction”, and then “Single Vehicle Wet Road Loss of Control; Effects of Tire Tread Depth and Placement”, Blythe & Day, SAE 2002-01-0553, and “Realistic Rear Axle Hydroplaning during Forward Motion” by, Metz, Kinney, and Herling, SAE 2006-01-1560
