A new partnership between The University of Michigan Medical School and OnStar is working to collect crash and injury information from specific vehicle crashes. Acting as an eyewitness, OnStar's Advanced Automatic Crash Notification transmits the crash severity, number of airbags deployed and location of the vehicle to an adviser, who passes that information along to first responders. With the permission of the owners and occupants the medical information, histories and x-rays are gathered and combined with the vehicle information to get a greater understanding of why injuries occur. This new research tool has the potential to improve emergency medical response techniques and improve vehicle safety.
