SureCross™ DX80 M-GAGE™ Node with Integrated Battery
Good Placement
Figure 10 shows the optimum placement of
M-GAGE™ sensors for vehicle detection.
When the sensor is positioned in the middle
of the traffic lane, it can be configured to
a threshold level to detect vehicles only in
the lane of interest. This is known as lane
separation, or not detecting a vehicle in an
adjacent lane.
A threshold level also aids the sensor in
vehicle separation – detecting a break
between the back bumper of a leading
vehicle and the front bumper of the next
vehicle. With proper placement and
configuration, the M-GAGE can achieve
vehicle separation with distances of 24
inches or less between vehicles.
Poor Placement
The drawing at left depicts a potential
problem installation. While mounting
the sensor at the side of a lane may be
successful, this mounting location increases
the potential for problems. To reliably detect
a vehicle from the side, the sensor threshold
must be increased to see objects further
away in the lane of interest. Unfortunately,
this enables the sensor to also detect lawn
mowers in the median or vehicles in adjacent
lanes, causing false counts.
Place the M-GAGE sensor at the edge of a
traffic lane only if there is no possibility of
the sensor detecting other objects. To avoid
detecting other objects, ensure no vehicles
will be within 10 feet of the sensor on the
non-traffic side.
