Emergency Vehicle Warning System (HAAS Alert): Virtual Technology Demonstration Report   [open pdf - 2MB]

From the Executive Summary: "First responder vehicles are frequently involved in motor vehicle collisions, and these collisions are increasing at an alarming rate. The use of emergency lights and sirens tends to not be as effective as it once was in getting the attention of other motorists in today's automotive landscape. This tragically results in substantial injuries among responders, loss of life, and property damage. These collisions also result in the responding units becoming unavailable to render aid at an incident. The personnel, vehicles, and specialized equipment they carry may not be available for subsequent service for some time afterwards. To address this issue, the U.S. Department of Homeland Security (DHS) Science and Technology Directorate (S&T) created a program to develop an Emergency Vehicle Warning System that could be used in car systems or phone applications to notify civilian drivers as they approach both en-route and on-scene emergency vehicles. The developed system was also intended to provide notifications for multiple emergency vehicles operating in proximity of one another traveling routes that may intersect. HAAS Inc. was contracted by DHS S&T to further develop and enhance their HAAS Alert technology to improve these functions and thereby provide a product that would help prevent collisions with first responder vehicles."
