Abstract
Apparatus, systems, and methods for detecting, alerting, and responding to an emergency vehicle. One such method includes receiving, using a first vehicle, a warning signal from an emergency vehicle. The first vehicle broadcasts a recognition signal based on the warning signal received by the first vehicle. A second vehicle receives the warning signal from the emergency vehicle and the recognition signal from the first vehicle. The second vehicle broadcasts a confirmation signal based on both the warning signal and the recognition signal received by the second vehicle. The confirmation signal is received from the second vehicle using a third vehicle. Finally, the confirmation signal is rebroadcasted from the third vehicle based solely on the confirmation signal received by the third vehicle.
