Midlands installed and
configured 645 detectors
at Trent Bridge.
Gough says, “We adjusted
the traffic light settings to
provide two levels of pedestrian
priority. Level 1 gives extra
green man time and extra allred
time when a large number
of pedestrians are waiting
to cross, and level 2 provides
even more green man time
and all-red time when a very
large group of pedestrians
are waiting.”
Gough and his colleagues
are very pleased with the
performance of the AGD 645
detectors, which will remain
at this site permanently.
“We have made some
adjustments to the detectors’
volumetric settings since the
initial installation to ensure the
best balance between pedestrian
utility and traffic congestion,
and we’re really pleased with
their performance,” he
concludes. “Going forward,
we will use the 645 as a tool
to solve specific issues related
to large fluctuations in
pedestrian and/or cycle flows
at other sites within the county
of Nottinghamshire, and
wherever required for our
traffic signal design clients
outside the county.”

Tactical approach
Until now, Nottinghamshire
County Council’s highways
team has been hard pressed to
address the issue of fluctuating
and often unpredictable
pedestrian demand. Without
data on the volume of
pedestrians wishing to use the
crossing, it has not been possible
to target the times when
pedestrians should be
afforded more priority.
This is why the team was
interested to learn that AGD’s
645 Pedestrian Detector might
be able to help. The 645 can be
employed to vary the crossing

times based on pedestrian
density, creating more
intelligent crossings that can
detect the volume of people
waiting and change the lights
accordingly.
“We were hoping that
the 645’s new volumetric
detection would allow us
to automatically provide
additional pedestrian priority
during busy pedestrian periods,
all without adversely affecting

Key facts about AGD’s
645 Pedestrian Detector
> Monitors a 10m (32ft)
x 3m (10ft) zone
> Real-time video can be
fed to control rooms for
remote zone adjustments
> Allows for dynamic
adjustment of crossing
times based on
pedestrian density
traffic flows during peak traffic
volume,” explains Gough.
The AGD 645 monitors
a 10m (32ft) x 3m (10ft) zone
with advanced optics that
ensure accurate detect and
reject, plus real-time video that
can be fed to control rooms
that allows remote zone
adjustments to be made.
Pedestrian behavior is
visible from the control room
via Ethernet IP connectivity,
delivering a richness of data that
was previously unavailable with
high reliability. This allows the
local controller to make
decisions in real time so when
the crowds subside, the signal
phases can be easily and quickly
returned to normal.
The 645 is part of AGD’s
comprehensive pedestrian
product suite that embodies
the company’s ethos of creating
safer, greener, more efficient ITS
solutions, complementing its oncrossing
detection and awardwinning
nearside signals to
ensure 24-hour pedestrian
crossing safety.
