Crash Investigation 2 Online is asynchronous and instructor led. At-scene traffic crash data collection is useful only if all appropriate data is properly collected, interpreted, and analyzed. Officers and investigators who successfully complete Crash Investigation 2 develop skills in technically preparing crash investigation data and collecting follow-up data. Building upon topics examined in Crash 1, students delve further into the information available at a crash scene, how to properly collect it, and how to initiate its interpretation. Like Crash Investigation 1, the course is rooted in Baker and Fricke’s Traffic Crash Investigation and emphasizes vehicle behavior in crashes, vehicle damage analysis, advanced measuring and mapping, properly downloading and preserving digital evidence from collision investigations, examining road marks and tire damage, and more.

Traffic Crash Reconstruction 2 builds upon the skills taught in Reconstruction 1 and focuses primarily on energy-based analysis. During this course, students learn the principles of energy and damage energy, occupant behavior, and momentum and energy analysis, and also receive an introduction to the concept of force balance.

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.
