Abstract: An alert transceiver in commuter vehicles in a line-of-site warning area receive line of sight (LOS) alert signals from another vehicle, such as an emergency vehicle. Upon detecting the LOS alert signal, the alert transceiver can relay the alert signals to other alert transceivers in commuter vehicles within a warning zone that are outside of LOS zone, thereby creating mobile tracking network (MTN). The alert signals can include any relevant information, such as information regarding a hazard that includes the type of hazard (emergency vehicle, fire, ambulance, etc.), the time stamped location, direction of travel, speed and planned route for the emergency vehicle; and/or the coordinates of warning zone as determined by alert transceivers.

Abstract: 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.
