It can be compared with the European TMC technology. VICS is transmitted using: * FM multiplex broadcasting (uses DARC). With this method, you have to manually select road conditions on-screen. *

Infrared Infrared (IR), sometimes called infrared light, is electromagnetic radiation (EMR) with wavelengths longer than those of visible light. It is therefore invisible to the human eye. IR is generally understood to encompass wavelengths from around ...
