SmartSensor Matrix
Bid Specication
1.0 General. This item shall govern the purchase of above-
ground radar presence detector (RPD) equivalent to the Wave-
tronix SmartSensor Matrix™.
An RPD detects vehicles by transmiing electro magnetic
radar signals through the air. The signals bounce o vehicles
in their paths and part of the signal is returned to the RPD.
The returned signals are then processed to determine trac
parameters.
RPDs are not aected by normal weather and environmental
conditions such as rain, wind, snow, dust, etc. They also do
not require cleaning and can maintain performance over a
wide range of ambient temperatures.
RPDs provide a non-intrusive means of detecting trac. This
property not only makes them safer to install but also more
cost eective than sensors that require roadway modications
or placement.
2.0 Sensor Outputs. The RPD shall present real-time presence
data in 10 lanes.
The RPD shall support a maximum of eight zones.
The RPD shall support four channels and have user-selectable
channel assignments.
The RPD shall use OR logic to combine multiple zones to a
channel output, and shall have channel output extend and
delay functionality.
The RPD algorithms shall mitigate detections from wrong
way or cross trac.
The RPD system shall have fail-safe mode capabilities for
contact closure outputs if communication is lost.
3.0 Detectable Area.
3.1 Detection Range. The RPD shall be able to detect and
report presence in lanes with boundaries as close as 6
ft. (1.8 m) from the base of the pole on which the RPD is
mounted.
The RPD shall be able to detect and report presence in
lanes located within the 100 ft. (30.5 m) arc from the base
of the pole on which the RPD is mounted.
3.2 Field of View. The RPD shall be able to detect and re-
port presence for vehicles within a 90 degree eld of view.
3.3 Lane Conguration. The RPD shall be able to detect
and report presence in up to 10 lanes.
The RPD shall be able to detect and report presence in
curved lanes and areas with islands and medians.
4.0 System Hardware. For each approach to be detected, one
RPD corner radar shall be used.
4.1 Preassembled Backplate. Each RPD shall have a traf-
c cabinet preassembled backplate with the following:
● AC/DC power conversion
● Surge protection
● Terminal blocks for cable landing
● Communication connection points
The preassembled backplate for the RPD shall be a cabi-
net side mount or rack mount.
4.2 Contact Closure Input File Cards. The RPD shall
use contact closure input le cards with 2 or 4 channel
capabilities.
The contact closure input le cards for the RPD shall be
compatible with industry standard detector racks.
5.0 Maintenance. The RPD shall not require cleaning or ad-
justment to maintain performance.
The RPD shall not rely on baery backup to store congu-
ration information, thus eliminating any need for baery
replacement.
Once the RPD is calibrated, it shall not require recalibration
to maintain performance unless the roadway conguration
changes.
The mean time between failures shall be 10 years, which is
estimated based on manufacturing techniques.
6.0 Physical Properties. The RPD shall not exceed 4.2 lbs. (1.9
kg) in weight.
The RPD shall not exceed 13.2 in. by 10.6 in. by 3.3 in. (33.5 cm
x 26.9 cm x 8.4 cm) in its physical dimensions.
All external parts of the RPD shall be ultraviolet-resistant,
corrosion-resistant, and protected from fungus growth and
moisture deterioration.
6.1 Enclosure. The RPD shall be enclosed in a Lexan EXL
polycarbonate.
