Abstract: A computer-implemented method for alerting passenger vehicles of approaching emergency vehicles is implemented by an alert management computing device. The method includes receiving an emergency vehicle alert request message from an emergency vehicle transmitter, receiving passenger vehicle location data from a plurality of passenger vehicle user computing devices located in a plurality of passenger vehicles, wherein the passenger vehicle location data includes a present passenger vehicle location and a present passenger vehicle trajectory, identifying an alert zone for the emergency vehicle based on the present emergency vehicle location and the present emergency vehicle trajectory, identifying a vehicle zone for each of the plurality of passenger vehicles, identifying a subset of the passenger vehicles within the alert zone by comparing each vehicle zone to the alert zone, and transmitting a warning to the subset of passenger vehicles via the passenger vehicle user computing devices.

Abstract: A radio opaque container for communication devices upon a vehicle has a bottom joined to four walls, a pivoting lid sealing upon the walls, a connector from the container to a vehicle, a locking mechanism keeping the lid closed, and circuitry between the locking mechanism and the vehicle that engages the locking mechanism only when the vehicle's electrical system is on. In an emergency, the contents within the container remain available to a vehicle operator but the container opens only when vehicle's electrical power has been turned off. The container forms at least one faraday cage around the contents and prevents equipment placed therein from activating and distracting a vehicle operator. In an alternate embodiment, the container includes a shelf therein.
