Event Data Recorder Use in Traffic Crash Reconstruction - Level II   

Print Course Description Download Registration Form

This course builds upon IPTM’s Event Data Recorder (EDR) Use in Traffic Crash Reconstruction - Level I by teaching you how to apply mathematical concepts to your EDR-based reconstructions.

We will begin by reviewing the math and physics concepts necessary to analyze EDR data in more complex non-central collisions. Topics such as the Law of Cosines; the Law of Sines; momentum; closing velocity; and change in velocity relationships will be discussed in detail. You will learn how each of these can be used in your reconstruction.

Actual EDR reports from a variety of collisions will be utilized to show you how to determine all the values necessary for a complete reconstruction. Projects and problem sets have been designed to reinforce the materials presented during lectures and will provide you with the tools you will need to complete actual reconstructions.

Topics Include

  • Solving momentum problems with EDR data when some data elements, such as departure speeds, departure angles, etc. are missing (aka “triangle momentum”)
  • How restitution affects your momentum-based reconstruction
  • The effects of rotation on delta-V and closing speed (Effective Mass Ratio)
  • The effects of external forces on momentum-reconstructions
  • Adjusting EDR delta-V for ACMs not located at the center-of-mass

Audience

Law enforcement and private traffic crash investigators, insurance fraud special investigators and claims adjusters, engineers1, attorneys, safety officers, military investigative personnel, collision animation and simulation graphics users

1Note to engineers: The first day is a review of trigonometry, which may not be necessary for engineers. Please contact instructor Andy Rich at arich@IPTM.org for more information.

Schedule Changes

This schedule is subject to change without notice. If you have not received an official confirmation email prior to the first day of class, please contact us at (904) 620-4786 or info@iptm.org before traveling or making airline reservations.

Registration and Fees

Full payment must accompany all registrations. You may register online and pay with your Visa, MasterCard, Discover or American Express credit card, or you may download a Registration Form and mail it to IPTM with a check.

Cancellation/Refund Policy

Complete the Cancellation Request Form and return it to IPTM. No telephone cancellations will be accepted. A 20% administrative fee will be assessed to all refunds if the cancellation request is received within 14 days of the course start date. In lieu of a refund, student substitutions can be made or a credit can be issued for a future course. No refunds will be given for no-shows. If materials for an online course were sent to the student, the appropriate materials and shipping costs will be deducted from the refund amount. Materials may be returned to IPTM in their original condition at the student's expense. Once IPTM has received and inspected them, the refund will be processed.

Due to the automated format of online independent study courses and Videos on Demand (VoDs), no refunds or substitutions can be made after registration.

Course Confirmations

A minimum number of registrations must be received for an in-person class to run as scheduled. When the minimum criterion has been met, written confirmation will be emailed to you. Please do not travel or make airline reservations until you receive written notification confirming that the course will run as scheduled.
