Abstract
An emergency vehicle alert system includes a traffic control device having a transceiver. The transceiver is configured to receive a first signal and to transmit a second signal. A receiver is configured to receive the second signal from the transceiver and to initiate an alert upon receiving the second signal from the transceiver. The first signal is transmitted to the transceiver from an emergency vehicle and causes the traffic control device to transition from a first configuration to a second configuration. The transceiver transmits the second signal in response to the transceiver receiving the first signal.
