VirtualSensor technology

VirtualSensor connects in a passive way to cellular networks and continuously monitors control channel communication of anonymous cellular phones. This data is immediately correlated with reference data using unique pattern matching algorithms to identify the exact road and extract accurate travel time. By continuous aggregation and analysis of this data for the whole covered area, VirtualSensor provides real-time travel time, traffic speed and incident reports for all relevant roads in all directions. Unlike traffic detection sensors that detect incidents and measure travel times at sensor locations only, the VirtualSensor technology allows travel time mesurements over dynamic travel intervals and accurate incident detection anywhere on the roads .

Technology Comparison


Technology	Cost	Coverage	Deployment	Other Limitations

Video Image Processing (FCD)Â	Very HighÂ	Highway only	Months, traffic obstacles at installation	Real time incident detection near cameras only

Active InfraredÂ	High	Highway only	Months, traffic obstacles at installation	Travel time not accurate

Inductive Loop DetectorsÂ	High	Highway only	Many months, Intrusive and dangerous road work	Travel time not accurate

Microwave Doppler RadarÂ	High	Highway only	Months, traffic obstacles at installation	Travel time not accurate

Toll tag detectors (FCD)Â	High	Mostly highway, very high cost to cover arterials	Years due to the need for a large installed-base in vehicles	Real time incident detection near detectors only

Cellint VirtualSensor (FCD)Â	Low	Highway and arterials with one central system	Weeks	Little information at late night times
