) to deliver the vehicle's GPS location, crash-related data and open a voice communications channel to the emergency call center.

The Advanced ACN improves the data sent from the ACN version, as it include crash-severity data (including: speed, delta velocity, number of occupants and rollover data) as collected by in-vehicle sensors. This additional data could be used by emergency services providers to determine the quantity and type of rescue equipment that should be dispatched.

Vehicular Emergency Data Set (VEDS)

The Vehicular Emergency Data Set is an XML-based standard for reporting collision data elements and medical data elements related to a collision. The standard was developed by the ComCARE Alliance, and is aimed at relaying critical information to facilitate efficient emergency response. This data set can be transmitted automatically to a response center, which can then forward it to emergency services providers. In the U.S., the Next Generation 9-1-1
