The infotainment and telematics systems in a number of vehicles store data from cell telephones and other systems within the vehicle. A valuable data element is GPS or navigation data; this information is retained in the form of tracklogs. This information can potentially provide a history of a vehicle’s geolocation. This could be useful when reconstructing and investigating an automobile accident. A team at Kineticorp is currently researching and exploring the data that is being recorded on various makes and models of vehicles.
The data obtained from event data recorders (EDRs) found in passenger vehicles has been extensively analyzed in peer-reviewed literature. Since the introduction of the commercially available Bosch Crash Data Retrieval tool in 2000, hundreds of vehicles have been tested and data from event data recorders has been validated. In 2016, Bortles, et al., provided a thorough review and analysis of all the known validation testing to date . They concluded, “The analysis presented here supports the notion that original equipment EDRs tend to be accurate, and tend to underreport Pre-Crash speed and ΔV values… EDRs provide valid and useful data that can be used as a supplement to a thorough accident reconstruction.” …..
