One version of ADEC’s TDC3 detector
provides configurable trigger output
to tie into third-party equipment, such
as LPR (license plate recognition)
or enforcement cameras.

ADEC Technologies’
TDC3 detectors
are used by the
major installers
throughout
Europe, and
are compatible
with all
common
roadside stations
thanks to the
implementation
of the long-proven
TLS standard that,
among other aspects,
defines the protocols used to
address the variable message signs.
The detectors are available in
different versions, both with respect
to the mounting location (in front of
or behind the gantry) as well as the
number of distinct vehicle classes they
can differentiate. Vehicle classification
is useful extra information for road
operators, for example to obtain
statistical information about the
composition of the vehicle classes or
adjust speed limits not only on the
overall traffic volume but the volume
of specific vehicles for example to
minimize environmental impact.
TDC3 detectors for classification
into the common TLS 8+1 classification
scheme offer accuracy of between 85%
and 99.9% (a figure that has been
independently verified). Special
versions of TDC3 detectors are also
available to retrofit older installations
from previous generations of
overhead double and tripletechnology
detectors from
other manufacturers.
Every day, for many years,
thousands of TDC3 overhead
detectors help to maximize the
traffic volume and minimize delays
from phantom queues and other
disturbances by delivering up-todate,
reliable and accurate traffic
data around the clock. Delaying
or even avoiding stop-and-go traffic
has great environmental advantages
as well, reducing the carbon impact
of primarily fossil-fuel fed vehicles. ■

class; and infrared PIR (passive
infrared) sensors to assess the exact
position of a vehicle in the lane. The
devices are specifically designed for
mounting on the many overhead
gantries already in use.
Overhead gantry mounting
eliminates the need to
damage the pavement
to insert inductive
loops, which in
themselves can
be a problem,
especially
in warmer
climates
or regions
with major
temperature
swings.
Overhead
detectors can also
easily adapt to lanes
that have been shifted to
accomodate construction works. Most
importantly, overhead detectors are
not limited to only working in ideal
highway conditions, unlike many
popular side-fire radar detectors. In
fact, they work perfectly in tunnels to
immediately detect queues or even
