Brief Description
The RTMS (Remote Traffic Microwave Sensor) measures the distance to objects in the path of
its microwave beam. This ranging capability allows it to detect moving and stationary vehicles
in multiple detection zones.
A single sensor can monitor traffic in up to 8-12 lanes. The sensor can be mounted on road-
side poles and aimed at a right angle to the road; this is referred to as the side-fired
configuration.
The internal processor calculates volume, occupancy, average speed and vehicle classifications
for each lane and transmits the information using its data ports and communication interfaces.
Optional contact closure outputs are also available for compatibility with loop based systems.

Introduction to the RTMS
The RTMS G4 (Remote Traffic Microwave Sensor — 4th Generation) is a true RADAR
device, designed for traffic sensing applications. It measures the distance to objects in the path
of its microwave beam. The ranging capability allows the RTMS to detect stationary and
moving vehicles in multiple detection zones. When pointed onto a roadway, the RTMS
microwave beam projects an oval footprint. Its range is divided into multiple micro-slices, in
which vehicles are detected.
The RTMS receives reflected signals from all surfaces within its beam—pavement, barriers,
vehicles and trees. It maintains a background signal level from fixed objects in each micro-
slice. Vehicles are detected when their reflected signal exceeds the background level in their
micro-slice by a certain threshold level. If that detection is part of a defined zone, its contact
(optional) is closed during the detection time to indicate detection and internal counters are
incremented. Statistical measurements are available through two ports, including optional IP
and Radio modems.
G4 User Manual © 2009 ISS Canada. 1-5

About the G4 System Chapter 1
Figure 1.1. RTMS Microwave and Beam Footprint
Several operating modes optimize internal parameter settings for highway and intersection
applications. Two mounting configurations are possible: side-fired and forward-looking.
In side-fired mounting:
•The RTMS is located on a roadside pole and is aimed perpendicular to the traffic lanes.
•Micro-slices corresponding to the location of traffic lanes are allocated as detection zones
during the setup process.
•Each detection zone consists of multiple micro-slices.
•The length of the detection zone is determined by the width of the beam's footprint.
In forward-looking mounting:
•The RTMS is mounted on an overhead structure and is aimed along the center of the lane.
•In highway applications the sensor's aiming angle is adjusted to confine the footprint to
one or two lanes.
•The RTMS accurately measures vehicle speed and travel direction.
Figure 1.2. RTMS Mounting Configurations
Vehicle Detection
RTMS technology allows accuracy in the following conditions, even with a relatively low
mounting-height:
•Severe weather.
•Strong vibrations common to roadways that carry large vehicles.
•When vehicles are completely occluded by other vehicles.

Chapter 2
RTMS G4 Installation
Side-Fired Mounting and Aiming
The distance between the close edge of the first lane of traffic to be monitored and the front of
the structure on which the RTMS is mounted is referred to as set-back. Set-back is a limiting
installation parameter of RTMS. More lanes can be covered with a larger set-back.
Use the diagrams in Figures 2.1, 2.2, and 2.3 to determine the setback required to monitor a
given number of lanes. The correct installation height can be determined once the set-back is
calculated. Height is measured relative to the road surface of the detection area. Do not
measure height from the bottom of the mounting pole.
Example: For 3 lanes the minimum set-back should be 5 feet [1.5m].

Note
It is almost always better to be 20 feet [6 m] further back from the
minimum than 2 inches [5 cm] closer than the minimum. If real estate is
available, move the RTMS further back.
The mounting height is based on the setback. Using the correct height value
allows the RTMS to be aimed so that it receives maximum return signal
while covering all required lanes. Mounting the RTMS at an incorrect
height will reduce accuracy.
Median strips are equivalent to lanes and must be included in total lane
count. For example: an eight lane road with a two lane-wide median strip
has 10 equivalent lanes.

RTMS G4 Installation Chapter 2
Mounting and Aiming Procedure
Warning
Installation ISS Canada hardware may require that you work above the
ground on a ladder or bucket truck. Please make sure you have all the
required equipment and are aware of potential safety issues before
starting any installation. DO NOT install any RTMS hardware if you
are unsure how to complete the installation or lack appropriate safety
equipment. ISS Canada does not recommend installing this hardware
during inclement weather.
The following equipment is required to mount and aim the RTMS unit:
•Provided By ISS Canada. RTMS unit and its housing.
•Not Provided. Bolts or stainless steel banding. The bolt specifications depend on the
mounting requirements: for example, different bolts may be required when the RTMS unit
is mounted on a wooden pole than when the RTMS unit is mounted on a concrete wall.
•Provided By ISS Canada. Lynch pin
•Not Provided. 7/16" wrench, 1/2" wrench, assorted tools to be determined by mounting
specifications.
To mount and aim the RTMS unit:
1. Attach the bracket to the roadside pole (or another specified location) using bolts or
stainless steel banding.
2. Secure the RTMS to the mounting bracket by inserting the lynch pin.
3. Aim the RTMS as indicated on the diagram above. A 7/16" wrench is required to
release/tighten the ball-joint bolt.
4. Adjust the RTMS to be perpendicular to the travel lanes and level side to side.
5. Look from behind the unit and use the top sight-ridge as a guide to align the bore sight.
6. Tilt so that the top of the RTMS is aimed to the first 1/3 of the monitored lanes.
7. Secure the position by tightening the bolt.

Chapter 2 RTMS G4 Installation
Set-Back Height Diagrams
Total width is the distance from edge of the first lane to the outside edge of the last lane.
Divide this number by the average lane width. For most applications, 12 feet is considered a
typical lane width. Example: total detection area = 120 feet; lane = 12 feet; 120/12 = 10
equivalent lanes.
Figure 2.2. Set-Back Distance Chart
Increase the setback as much as possible if room is available. Then obtain the proper mounting
height based upon actual set-back distance.
Figure 2.3. Mounting Height Chart.
Zero Setback Options
Current generation hardware/software has new features that enable the RTMS sensor to work
with zero setback. For example: zero setback might be required for installation on a bridge.
However, appropriate setback distance should always be used when setback is available.
•The zero setback feature has a maximum range of ~50 feet or 4 lanes of traffic.
•Recommended mounting height is 14 feet.

RTMS G4 Installation Chapter 2
Cabling
Surge Suppression
Each RTMS unit has built-in surge-suppression hardware. Please keep in mind the following:
•ISS Canada recommends installing external surge-suppression devices with every detector.
•The communication and power lines of the RTMS should be equipped with external surge-
suppression devices when long cable runs are required.
•Install surge-suppression devices close to the sensor. For example, in a cabling cabinet
mounted on the pole below the RTMS.
See Recommended Surge Protection for further details on installing surge-suppression devices.
The RTMS Cable
The RTMS ships with all required connectors, crimp pins, and back-shells.
•RTMS G4 units (same as earlier RTMS models) use a single 32-pin MS connector for
power and communications.
•The RTMS cable should be made from 20 or 22 gauge stranded wire arranged in twisted
pairs.
•Cables exposed to outdoor conditions should be UV shielded.
The number of pairs required depends on the communication options chosen:
Table 2.1.Cable Pair Requirements
Communication Options Number Of Pairs
Standard RS232/485 plus power 5
Standard RS232/485 and Internal RF modem option
plus power 5
RS232/485 and TCP/IP plus power 7
RS232/485 and second serial port RS232/422 plus
power 7
Zone contact option added to any of the above:
Add 1 wire per zone for each option.
Option 1 (Maximum 16 contacts)
Option 2 (Maximum 8 isolated
contacts)
Preparing a Cable
Use cable such as the Belden number 95xx (xx indicates number of pairs. For example: 9516 is
a 6-pair cable). In preparing a cable note the following:
•Decide whether or not to install extra cable pairs for growth purposes.
•The crimp pins are designed for stranded wire only.
•Do not use cable employing solid wires.
•ISS suggests the Daniels Manufacturing Corporation crimping tool M22520/1-01 AF8
with head number M22520/1-02 or equivalent.
•Do not solder crimp pins!

Chapter 2 RTMS G4 Installation
Connecting a Cable to the RTMS
Use the following procedure to connect a cable to the RTMS device:
1. Thread cable through the backshell before inserting pins into shell.
2. Use the insertion tool (red) to insert wires with crimped pin into shell.
3. Use the extraction tool (white) to remove a crimped wire to correct an error.
4. Access to the serial connection should be available within view of the monitored lanes.
−For example: inside an access panel or cabinet on the pole.
−Verifying the sensor's calibration is easy when the user sees the RTMS data together
with manual counts.
