Emergency Vehicle Alert System Presentation
A state of the art visual signal to civilian drivers that an emergency vehicle is coming through the intersection.
When the Emergency Vehicle begins an emergency run, a transmitter installed in that vehicle is activated, sending an encrypted signal to a receiver in the EVAS device. When the transmitted signal is received by the EVAS, the fire truck symbol begins to flash in all directions of traffic. Click here for more.
