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.
