SUMMARY:
I will be working with a CSV file recorded during an acceleration/braking event using the G-Field Recorder phone-app. We will digitally integrate the accelerometer data to get speed. If time permits, I'll compare these results with a VBox Sport running at the same time during the test. Topics will include:
-File structure & saving your work - don't lose original file!
-digital integration of acceleration - multiply time step duration by ft/s/s to get ft/s speed change in each step, then sum them all all to get total speed change.
-Setting up columns for simple chart generation, or selecting non-contiguous columns
-Adjust bias out of signal acceleration data, shifting timebase to line GPS and calculated speed values
-Borders, gridlines, axis labels, titles, fonts, colors
-Dual axis charts - managing color & scales
-Legend, if you must
-Sharing your chart - printing or inserting into a report
One possible result from the file we'll be using looks like this:
Finding A/B stiffness values from NHTSA data - 2 hour Zoom with Dan Vomhof 3rd
We will have Dan Vomhof III (Known to many as DV3) with us to show us how to find A & B stiffness coefficients from NHTSA crash test data.

MOTORCYCLE COLLISION RECONSTRUCTION
INSTRUCTOR: LOU PECK
The Motorcycle Collision Reconstruction course equips the analyst with a firm understanding of motorcycle dynamics and current reconstruction techniques through deep review of literature, sample evidence, and exercises. The following topics are covered:
Introduction to motorcycle crash causation, motorcycle anatomy, and specification research
Review of kinematics including units, conversions, and derivations of basic equations
Fundamentals of motorcycle dynamics (geometry, stability, steering, weight transfer, suspension, etc.)
Motorcycle inspection
Rider perception-response time
Braking systems and rider performance
Introduction to Excel for collision reconstruction
Dynamics of swerving and rider performance
Acceleration behavior, calculations, and gearing analysis
Sliding friction for downed motorcycles
Analysis of wheelbase reduction for determination of impact speed
Angular momentum
Rider and pillion vault analysis
Event data recorders and dataloggers
Simulation analyses for impact speed determination
Monte Carlo analysis to determine confidence in speed ranges
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).
