Using E.D.R. Pre-Crash Data to Calculate a Range for Speed at Impact
Event Data Recorders (EDR), which are included with most modern vehicles, record pre-crash data and include a value for speed just prior to crash. A number of factors can complicate the relationship between the EDR's last-documented speed and the actual speed at impact (SAI), including: data latency, speedometer errors, asynchronously collected data, and wheel slip. In this article, the authors offer a model to account for these factors and determine a range for SAI based on EDR's pre-crash data. Crash reconstructionists look to understand vehicle speed and they have a duty to relate EDR data to the crash under investigation. The authors suggest the importance of comparing EDR data with other available data for consistency.
