BASIC HUMAN FACTORS IN CRASH RECONSTRUCTION
Instructors: Driver Research Institute
August 4, 2025 - August 8, 2025
Location: Oklahoma City Police Department Training Facility Building #3
3738 SW 15th St
Oklahoma City, Oklahoma 73108
This course is designed to introduce crash investigators, technicians, and crash reconstructionist to various driver response research in emergency situations as well as introduce them to research dealing with non-immediate responses also. Te attendee should have a thorough understanding of Time and Distance formulas on how to calculate speed in moving situations as well as to/from a stop situation, and constant speed situations. The goal is to introduce attendees to the foundations of driver response research, specifically, response times and nighttime recognition distances. The class is designed to meter out the tremendous amount of information between stories and examples that reinforce learning.
The average response times of common response time scenarios are discussed and practiced. Also, the results from nighttime recognition distance studies are discussed.
RESPONSE (formerly IDRR) software - attendees will receive a 30 day trial.

MOTORCYCLE COLLISION RECONSTRUCTION
INSTRUCTOR: ANDREW THOMAS
Andrew will be instructing the class, using Lou’s material
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

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.
