Advanced Investigative Techniques
-
Body Language: Unspoken Communication for Expert Witnesses (Alan Moore)
- Alan Moore, P.E., A.B. Moore Forensic Engineering
A significant part of human communication occurs non-verbally, which is known as body language. It is valuable for a testifying expert to understand body language, both to help convey meaningful testimony and to understand how listeners (such as lawyers and jurors) are absorbing the testimony. In this real-world discussion, Alan Moore will teach you how to use body language to improve expert testimony.
-
Fundamentals of Rotational Mechanics for the Traffic Crash Reconstructionist (John Daily)
- John Daily, MSME, Jackson Hole Scientific Investigations, Inc.
Further your Traffic Crash Reconstruction knowledge with this advanced course on Rotational Mechanics. In investigating collisions, rotational motion may be present along with translational motion. We will discuss how you can calculate delta-v vectors not only at the CM, but at other locations within the vehicle, assisting with occupant kinematic analysis. Examples of reconstructions completed with rotational mechanics will be presented.
-
Expert Testimony in Vehicular Crimes Cases (Aaron Harder)
- Aaron Harder, Bureau Chief - Vehicular Crimes, Maricopa County (AZ) Attorney's Office
Learn how an officer becomes qualified as an expert witness for trial in this session with Bureau Chief Aaron Harder. He will discuss the Daubert and Fry standards for collision reconstruction testimony and evidence; best practices for presenting collision reconstruction testimony during trial; and what to expect from jurors. You will also learn about scene investigation and how prosecutors and collision reconstruction experts work together at a scene to obtain all relevant evidence to present to a jury. The session will end with volunteers demonstrating trial testimony.
-
Nighttime Recognition of Objects: What Can We Really See (Swaroop Dinakar)
- Swaroop Dinakar, Managing Scientist - Human Factors, Driver Research Institute, LLC
Research has shown that in dark lighting conditions, many factors can affect a driver’s ability to recognize pedestrians, vehicles, or other objects in the roadway. This interactive presentation will discuss these factors with case examples and videos. You will learn how to approach your investigations by applying the appropriate methodology and avoiding any biases. The presentation will address what numbers to use when testifying and how to support your opinions in courtroom questioning.
-
Peeling the Onion: A CMV Distracted Driving Case Study (Steven Schmit)
- Corporal Steven M. Schmit, Pennsylvania State Police
Using a 2014 fatal case study that involved a commercial motor vehicle that struck a pedestrian, we will look at the various elements of the investigation; what went well, what could have been improved upon, and how distraction, driver fatigue, and poor company philosophy ended with disastrous results. What started out as a "routine" fatal collision investigation quickly unfolded into a multi-layered tale of negligence and reckless behavior leading up to the collision. This case study is designed for both collision investigators and enforcement officers.
-
Speed and Motion Through the Digital Lens (Josh Guthrie)
- Josh Guthrie, Force Analysis and Multimedia Review
Attendees will be introduced to methods for determining speed and motion from video evidence. Obtaining accurate timing information from video evidence will be examined. In addition to timing, methods for determining distance from video evidence and 3D scan data will also be discussed and demonstrated through case studies.
-
A Tire's Role in Crash Investigation (T.J. Tennent)
- T.J. Tennent, The Tyre Guy, Tennent and Associates
Understanding a tire’s language can give you the advantage needed to determine the success or failure during an investigation. The tire(s) are important to a crash, whether they have become disabled or not. It is your job to not only understand the language that the tire is speaking but be able to translate it so that everyone understands what it is telling you.
-
Using a Scientific Method to Evaluate a Driver's Response (Swaroop Dinaker)
- Swaroop Dinakar, Managing Scientist - Human Factors, Driver Research Institute, LLC
This presentation will explain how drivers' response times are related to the comparative probability of the event. More common events like cut-offs and suddenly slowing lead vehicles associated with faster response times, but lower probability events such as head-on crashes, U-turns, and pedestrians at mid-block locations at night being associated with longer response times.
Crash Testing
-
Live, Instrumented Crash Testing (Sponsored by CARFAX for Police)
Bill Wright, M.E., Symposium Crash Team Coordinator, will lead IPTM’s team of renowned crash reconstructionists as they conduct staged pedestrian crashes, gather, and analyze all the data. Full test data will be available after the conference. -
Post-Crash Data Analysis and Review (Wright, Harmon and Rich)
Bill Wright, M.E., Andy Rich, M.E., and Ken Harmon will present their findings and analyses of the live, instrumented crash testing during two identical breakout sessions on Thursday morning.
EDR
-
EDR in Traffic Crash Reconstruction Update (Andy Rich)
- Andy Rich, M.E., Principal, Rich Consulting LLC
This session will provide you with the latest updates to EDR equipment, software and the new data available. Andy Rich will discuss known issues with hardware, software and data, and explain the latest updates to EDR access law, EDR regulations, and research supporting EDR data admissibility.
-
Investigating EDR Anomalies Using 3D Simulation (Brian McHenry & Stanley McHenry)
- Brian McHenry and Stanley McHenry, McHenry Software
EDRs tell part of the reconstruction story. They are a great additional piece of the crash reconstruction puzzle, however they have issues/failures and do not tell you everything you need to know about a crash. Using a 3D simulation program can help when things go wrong with EDRs results. This presentation will add additional crash investigations and raise important issues to be considered and addressed when reconstructing a crash with an EDR.
New Technology
-
