This course will teach the student how to analyze any event data recorder (EDR) data they encounter, regardless of manufacturer. The student will also learn how to analyze the EDR data which has been collected with imaging tools. During the course, you will learn how to:
Topics will include:
- Analyze any set of EDR data you encounter, regardless of manufacturer
- Determine if the event recorded is from your crash
- Identify circumstances where EDR data is incomplete or has nothing to do with your crash
- Understand Delta-V
- Use EDR Delta-V along with other scene evidence to get closing speed and speed at impact
- Use Delta V from the vehicle with the recorder to determine the Delta V of the other vehicle
- Recognize vehicle operational conditions that would cause EDR speed data to not accurately reflect true vehicle speed
- Determine the effect that equipment modifications have on EDR speed data
- Use pre-crash data to identify when a vehicle lost control in order to select the peak speed before the vehicle lost control
- Calculate the appropriate ranges for Speed at Impact for different EDR’s
- Use time-distance analysis to estimate the point of first perception
- Utilize EDR data to gain previously unavailable insight into driver behavior and approach speed
- Use OEM specific Excel© templates to analyze EDR data
- Support Frye and Daubert hearings with references to copyrighted research and non-copyrighted items
- Show analytical tools techniques for heavy truck data
