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.
