"The idea behind TrafficSense is built on the premise
that increasingly, everybody has their cell phone on
while they're driving," explained Modena, Cellint's Vice
President of Business Development and Marketing.
"The information is relayed directly to the traffic
management system of the road operator - it's quick,
easy to install, and there's no problem with privacy.
It finds the exact locations of all active mobile phones
without burdening the cellular network and without
changing it in any way, simply by analyzing the control
signals on the cellular network.
Unlike traffic detection sensors that detect incidents
and measure travel times at sensor locations only,
the TrafficSense technology allows travel time
measurements over dynamic travel intervals and
accurate incident detection anywhere on the roads.
While those approaches showed promise at the time,
none of those early efforts proved both economically and
operationally feasible for transportation applications.
The major testing ground for TrafficSense has been
the Ayalon Freeway, the main highway in Tel Aviv
where the system has been operational since 2002.
This issue becomes vital when dealing with the
system Cellint has developed for drivers, which will
revolutionize the way in which commuters will get from
place to place.
TrafficSense from Cellint uses anonymous signaling
on cell phones to directly relay traffic information
quickly and easily. Cellint's "VirtualSensor"
technology finds the exact location of the mobile
phone by analyzing the control signals on the cellular
network.
