![]() ![]() ![]() In early 1998, the National Highway Traffic Safety Administration's Office of Research and Development formed a working group comprised of industry, academia, and other government organizations. In 1997, the National Transportation Safety Board (NTSB) issued recommendations to "pursue crash information gathering using EDRs." NASA's Jet Propulsion Laboratory, in April of the same year recommended that NHTSA "study the feasibility of installing and obtaining crash data for safety analyses from crash recorders on vehicles." They can make a major impact on highway safety, assisting in real-world data collection to better define the auto safety problem, aiding in law enforcement, and understanding the specific aspects of a crash. EDRs are devices which record information related to an "event." In the context of this site the event is defined as a highway vehicle crash.ĮDRs can be simple or complex in design, scope, and reach. We are not using the term to include any type of device that either makes an audio or video record, or logs data such as hours of service for truck operators. For instance, EDRs may record (1) pre-crash vehicle dynamics and system status, (2) driver inputs, (3) vehicle crash signature, (4) restraint usage/deployment status, and (5) post-crash data such as the activation of an automatic collision notification (ACN) system. When we use the term EDR in this site, we are referring to a device installed in a motor vehicle to record technical vehicle and occupant information for a brief period of time (seconds, not minutes) before, during and after a crash. Since the term "EDR" can be used to cover many different types of devices, we believe it is important to define the term for purposes of this research site. ![]()
