The purpose of this document is to describe the design for the human machine interface (HMI) display for the Next Generation 9-1-1 (NG9-1-1) System (or “system of systems”) based on the initial Tier 1 requirements identified for the NG9-1-1 System. The ubiquitous access to 9-1-1 emergency services needed in today’s world of evolving technology is driving the need to introduce a broader array of interconnected networks that would comprehensively support emergency services. The U.S. Department of Transportation (USDOT) is leading the effort to introduce the NG9-1-1 System, which is designed to improve management of emergency services throughout all aspects of operations, including public access to the emergency services; facilitation of services; and
delivery of emergency information to public safety answering points (PSAP), emergency call centers (ECC), and first responders.
USDOT views the NG9-1-1 System as a necessary transition to enable the general public to make a 9-1-1 “call”1 from any wired, wireless, or Internet Protocol (IP)-based device, and allow the emergency services community to take advantage of enhanced call delivery and advanced functional and operational capabilities through new internet working2 technologies based on open standards. By enabling access to 9-1-1 services through virtually any communications device, the NG9-1-1 System provides a more direct ability
to request help or share critical data from any location with emergency services
providers. In addition, call takers at the PSAPs will be able to transfer emergency calls to another PSAP and forward the location and other critical data, such as text messages, images, and video, with the call.
