An apparatus and method for an emergency vehicle alert system transmits signals
from one or more emergency vehicles to nearby commuter vehicles. When an initiation
switch in the emergency vehicle is activated, a transmitter broadcasts a unique
identifier for the vehicle. Information regarding other characteristics such as
position, speed, route, and direction of travel can also be transmitted to provide
alert information to commuter vehicles in the vicinity of the emergency vehicles.
The information is presented to occupants of the commuter vehicle and can include
audio and visual displays such as lights, voice warnings, moving map display with
symbols representing the vehicles' position relative to one another, and a textual
display providing identification and distance information.
