Vehicle Information and Communication System ( VICS ) is a technology used in Japan to transmit information about traffic jams and adverse traffic conditions to drivers.
According to its functional characteristics, this system is an analogue of TMC (Traffic Message Channel) technology. See also road traffic channel
Working Principle
Data on road conditions and road incidents can be displayed in car navigation systems in three ways:
- Level-1: Text Information
- Level-2: Charts
- Level-3: Superimposed on the map (including traffic data)
Thus, navigation systems provide drivers with the opportunity to receive free of charge information on their navigator about service stations, parking places, road works, traffic jams and traffic restrictions, as well as the time that can be stuck in a traffic jam, and alternative routes.
The data sources are: radio and optical beacons, sensors and cameras installed along the roads; patrol cars and motorists calls. [one]
For data transfer can be used:
- Infrared radiation
- Microwave radiation in the ISM-range .
- FM , on the same principles as in RDS .
In terms of the number and prevalence of cars equipped with navigation systems , Japan is one of the world leaders, which is largely due to the active state support for traffic optimization technologies. Currently, traffic problems in this country cannot be solved only by improving roads and increasing their number, since the land here is very expensive, and construction takes a considerable time. Therefore, according to the Japanese, the optimization of the route of each car will help to reduce driver fatigue and ultimately reduce the number of accidents and traffic accidents. An additional advantage may be more efficient use of fuel (and this is also a sore point in Japan's resource-poor) and improved environmental situation.
Currently, the largest car manufacturers in Japan ( Toyota , Nissan , etc.) offer cars equipped with navigation systems with support for VICS technology. Support for VICS technology is also provided by manufacturers of navigation systems. [2]
