Document Type: Informational
Number: 07-504 v1   (***No further updates to be made - reference only***)

The purpose of this "Automatic Collision Notification and Vehicle Telematics Technical Information Document” is to understand and describe in both technical and operational terms the current telematics industry and telematics emergency calls and associated information delivered to Public Safety Answering Points (PSAPs). The document scope also reflects on the current 9-1-1 infrastructure, the next generation emergency networks, and it discusses the integration of telematics emergency calls and information into those networks. This Technical Information Document (TID) will provide information to allow the National Emergency Number Association (NENA) and other interested parties to develop new communications methodologies and protocols to facilitate emergency communications between Telematics Service Providers (TSP) and PSAPs.


A variety of services are available through telematics suppliers. Some services are only available using specific equipment and/or service vendors. Generally the services fall in five categories: emergency, navigation, convenience, vehicle, and dealer/manufacturer services. This document will address only two specific services within the Emergency Services category, and those are: Emergency Services and Telematics Call Centers.

  • Mayday calls – Occupant pushes button in the car to summon help
  • Automatic Collision Notification – Call is initiated by a collision’s characteristics, without occupant intervention, usually air bag deployment or seat belt tensioning system deployment. Newer systems may be activated by impact with the car, from any direction without airbag deployment.
