Claim 19:
20. An alert management system for monitoring an emergency vehicle and a passenger vehicle, the emergency vehicle having an emergency vehicle transmitter configured to transmit information including a present location of the emergency vehicle to the alert management system and the passenger vehicle having a passenger vehicle transmitter configured to transmit information including a present location of the passenger vehicle and at least one of an emergency vehicle speed and an emergency vehicle acceleration to the alert management system, the passenger vehicle further having a passenger vehicle receiver and an emergency warning device coupled to the passenger vehicle receiver, the alert management system comprising:
a receiver for receiving the information transmitted by the emergency vehicle transmitter and by the passenger vehicle transmitter;
a processor coupled to the receiver adapted to determine an alert zone for the emergency vehicle having an area determined as a function of the information received from the emergency vehicle transmitter including the present location of the emergency vehicle and at least one of the emergency vehicle speed and the emergency vehicle acceleration and to determine a vehicle zone for the passenger vehicle as a function of the information received from the passenger vehicle transmitter;
wherein the processer is further adapted to:
expand the area of the alert zone in response to an increased speed or acceleration of the emergency vehicle; and
contract the area of the alert zone in response to a decreased speed or deceleration of the emergency vehicle;

wherein the alert zone includes an area next to the emergency vehicle;
a transmitter for transmitting information to the passenger vehicle receiver, wherein the processer is coupled to the transmitter and is configured to:
compare the alert zone for the emergency vehicle to the vehicle zone for the passenger vehicle; and
send an alert signal via the transmitter to the passenger vehicle receiver as a function of a partial overlap between the alert zone and the vehicle zone,
whereby the emergency warning device is activated in response to the alert signal to provide a warning in the passenger vehicle.
