Advanced Automatic Collision Notification

Advanced Automatic Collision Notification (AACN) is the successor to Automatic Collision Notification (ACN). To develop procedures that will help emergency medical responders better and more quickly determine if a motorist needs care at a trauma center after a vehicle crash, Center for Disease Control and the CDC Foundation recently partnered with OnStar and the GM Foundation. Through this partnership, CDC conducted a vehicle telematics initiative to develop evidence-based protocols for the emergency medical community to effectively use automotive telemetry data. By enabling responders to more quickly identify, diagnose, and treat injuries, these data will help to reduce death and injuries among vehicle crash victims. As part of this initiative, CDC convened a panel of emergency medical physicians, trauma surgeonspublic safety, and vehicle safety experts. The panel considered how real-time crash data from the advanced automatic crash notification (AACN) vehicle telematics system and similar systems can be used to determine whether injured patients need care at a trauma center. By using a collection of sensors, vehicle telemetry systems like AACN send crash data to an advisor if a vehicle is involved in a moderate or severe front, rear, or side-impact crash. Depending on the type of system, the data include information about crash severity, the direction of impact, air bag deployment, multiple impacts, and rollovers (if equipped with appropriate sensors). Advisors can relay this information to emergency dispatchers, helping them to quickly determine the appropriate combination of emergency personnel, equipment, and medical facilities.
