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 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 for each micro-slice. Vehicles are

detected when their reflected signal exceeds the background level in their micro-slice by a

certain threshold. If that detection is part of a defined zone, its contact (optional) is closed

during the detection period to indicate detection. Statistical measurements are available

through two data points, including optional IP and Radio modems.

Chapter 1 About the G4 System

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 the 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

set. 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 is 5 feet [1.5 m].



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.

Figure 2.1. RTMS Aiming

Chapter 2 RTMS G4 Installation

Mounting and Aiming Procedure

Warning

Installation of 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. Lynch pin.

 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.

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 Figure 2-1. 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 the close 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. Minimum setback is 5 feet. Minimum height is 17 feet.

Figure 2.2. Set-Back Distance Chart

A setback greater than the minimum is desirable if room is available. Obtain the proper

mounting height based upon actual set-back distance.

Figure 2.3. Mounting Height Chart.

Zero Setback Options

The G4 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 Max range of ~50 feet, or 4 lanes of traffic.

 Recommended mounting height is 14 feet.

Chapter 2 RTMS G4 Installation

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

ports

Zone contact option added to any of the above:

Option 1 one wire for each contact

(Max 16)

Option 2 two wires (1 pair) for each

contact (Max 8)

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 to create 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.

MS Connector Pin-Out

Caution

Pin labeling in Figure 2-4 is a guideline only – verify pin location on

actual connector before inserting wire.

Warning

The RTMS unit can be configured for a variety of communication

options. It is important to know which options are included with your

unit prior to preparing cables. MS connector pins cannot be shared.

Dual RS-232 Ports

The G4 has two independent serial ports (only available with additional hardware). The

primary port can be soft-configured to RS-485 operation for increased range. The secondary

port can be soft-configured to RS-422. The second port is also used when another device such

as an RF Modem or TCP/IP server is ordered with the unit. Below is the wiring for two

independent RS-232 ports configuration. Each port can be operated separately at its own speed

and carry different streams of information.

Contact Closure

The G4 can provide, in parallel with the serial port and RF/IP/Cellular communications, up to

16 contact closures, delivering real time presence indication in each of its detection zones. The

contacts are arranged in two wiring configurations and operating modes:

 8 Isolated contact pairs (as in RTMS Models X2/X3 and K3). In this configuration each of

the contacts is isolated from the other.

 16 contact pairs. In this configuration all contacts will share a common Serial Ground. The

contact closures can be configured to operate either in Single Loop mode or Dual Loop

(Speed Trap) mode. Single mode provides up to 12 lanes or zones of detection, Dual mode

provides up to 8 lanes of Dual Loops.

You should wire the cable based on your preferred contact closure output mode and set the

RTMS mode using the Contact Closure Setup in the Advanced screen of WinRTMS.

Connecting RTMS to External Modems

The RTMS may be connected to a remote traffic data collection system over private telephone

lines using modems.

Multiple RTMS units connecting to remote systems, including the Cluster Hub or NEWS Hub

systems must be placed in Polled mode and may require the use of modems.

Modem Cables

A cable connecting the RTMS RS-232 port to the modem's RS-232 port must provide the

following:

 Male connectors at both ends (null cable).

 The cable must operate within the parameters provided below.

A modem's RS-232 ports will usually employ DB9 or DB25 connectors.

RS-485 Multi-Drop

The RS-485 setting of the G4 Serial Port allows up to 32 RTMS units to be employed on the

same serial bus over distances up to 4000 feet [1200 m].

The diagram Figure 2-12 shows the use of a 4-Wire line. The use of a half-duplex 2-Wire line

is feasible but it is suitable for data collection only. Consult RS-485/422 Application Guides

for details on wiring solutions for your project.

Figure 2.12. RS-485 Multi-Drop Wiring

Chapter 2 RTMS G4 Installation

Wiring Notes

1. The DB9 connectors and terminal blocks serve as a disconnect point, which allows

disconnecting the RTMS from the transmission line for direct connection to the laptop's

COM port for setup.

2. Terminating resistors (100-120 ohms) are required at the extreme ends of the Receive and

Transmit transmission pairs.

3. Transmit and receive pairs must be transposed when connecting to a DTE (PC, Data

processing System). To interface with a PC an RS-485/232 converter may be required as

PCs typically do not have RS-485 interfaces.

4. RS-485/232 converter connector type and pin assignment are not shown as these are not

standardized and vary between models.

RTMS Troubleshooting Guide

Field troubleshooting of the RTMS consists mainly of ensuring that the unit is powered and

communicating. Communication with the sensor in Normal mode is confirmed by presence of

the moving vehicles and menu buttons, and by the flashing of the indicator in the lower right

corner of the screen, denoting data transmission activity. The table below outlines symptoms

and suggested action in troubleshooting power and communication problems. Further

information on problems with the power supplied to the unit, with the wiring, or with the

communications parameters not being set correctly is provided below the table:

Notes on Power:

The RTMS G4 is a constant power device that requires in its basic configuration 3 watts of

power. Electrical power has two components, voltage and current; both must be available in

Chapter 2 RTMS G4 Installation

the correct ranges to operate the G4.

The voltage must be between 12 and 24 volts (DC or AC RMS) with the voltage level read at

the RTMS. Voltages below 12 volts will be insufficient to turn on the G4; voltages above 24

volts will cause the G4 to shut down to protect itself from an overvoltage condition. Losses in

the cable must be addressed in setting the voltage to be supplied to the unit.

Current in sufficient quantity must be available: at 12 volts, the G4 will draw 250 mA of

current; at 24 volts 125 mA (base model, higher for units with additional communications

options).

Using an adaptor that provides 12 volts and 100 mA of current means that the total power to

the RTMS will be 12*0.1 = 1.2 watts, or roughly 40% of the power needed to turn the G4 on.

On power up, there will be an inrush current that will be several times higher than the

operating current. The power supply must be able to handle this temporary current flow.

If the power supply is unregulated (such as a simple step-down supply from 120 VAC to 24

volts (AC or DC)), the output voltage may be higher than specified when the current draw is

less than maximum available from the supply This may cause the G4 to sense an overvoltage

condition and shut down to protect itself.

If additional hardware is added to the G4, such as a radio modem or an Ethernet card, the

power required to operate the G4 will increase. The voltage seen by the G4 will remain the

same, but the current will increase to meet the new power requirement.

Note on Cabling:

ISS Canada recommends that the design of an RTMS installation include a breakout box close

to the RTMS that can be used for setup and maintenance purposes, and can include surge

suppression circuitry and external communications devices as required. Reference designs are

available.

Notes on Communications:

The base communication method used with the G4 is serial RS-232 or RS-485. Port 1 is the

main port that is connected to the outside world, Port 2 (optional) is installed to speak with

other internal devices such as a DSS or Cellular radio, or a serial-to-Ethernet converter. Port 2

can also be connected to the MS connector for direct access to the outside world (factory

option).

It is recommended that serial port 1 be accessible to the outside world for maintenance

purposes, even if the primary communication with the G4 will use another method.

Communication between the second serial port and another device will be fixed at a rate of

115200 bps. When connecting to an internal device through the serial ports, it is necessary that

serial port 1 is set to 115200 bps for the connection to be successful.

Both serial ports can support hardware handshaking if the external lines are available. It is

critical that hardware handshaking (RTC/CTS) not be enabled using the WinRTMS software if

the lines are not installed in the cabling. Enabling RTS/CTS without these lines will prevent

the RTMS from communicating with the outside world.

*Accuracy Performance Conditions

Error performance parameters outlined above are achieved under normal, high-flow traffic

conditions and are subject to proper installation and setup. Lower accuracy is expected under

the following conditions:

 Low speed, high congestion conditions: The RTMS tends to be less accurate under very

low speed conditions (below 1 mph [1.6 km/h]).

 Improper selection of installation site: insufficient set-back, height beyond the

recommendation, obstruction by barriers or high fences before monitored lanes.

 Improper fine tune setting for the road geometry (lane width, barriers, etc.) will result in

―splashing‖ and, therefore, over-counting.

 In Forward-Looking Hwy configuration the following conditions may result in errors:

 High variance between the volumes in the speed trap zone.

 Improper aiming, mounting height (too high) or incorrect offset parameters

 Obstructions within the trap range.

Recommended Surge Protection

It is recommended that communication and power lines of the RTMS be equipped with surge

protecting devices, located as close as possible to the sensor. For example: locate surge

protection in a cabling cabinet mounted on the same pole as the RTMS. The surge suppression

should be applied as follows:

 The Tx and Rx communication lines should employ low capacitance, bipolar surge

suppressors with a clamping voltage of 15 V.

 The Signal ground line should be grounded.

 A bipolar surge suppressor with a clamping voltage of 40 V shall be placed between two

low voltage (16-18V AC or 12-24VDC) power lines.

 One of the power lines, negative line in case of DC, shall be grounded.

How to Use the Automatic Setup Wizard

The automated zone setup process requires free flowing traffic in all lanes of interest. It scans

the range of the RTMS microwave beam and positions up to 12 detection zones—representing

lanes where vehicles are detected.

The WinRTMS software automatically detects traffic in its detection area and configures lane

parameters accordingly. This is a two-stage process:

 WinRTMS finds the lanes.

 WinRTMS fine tunes the lane assignment/detection parameters.

 You may receive warnings while detecting traffic in low-volume lanes. The warning

asks if you would like to continue detection for 1 additional minute. In some cases, such as

when the detector overlaps an exit ramp, continuing the wizard provides little benefit.

To perform Automatic Setup:

1. Click the button named Wizard Setup

Chapter 3 G4 Software

2. The resulting zone setup is presented for approval on the detection map when the Progress

Bar reaches its 100% point. The wizard sets sensitivity and positions detection zones

where vehicles are detected.

 Using the blips, confirm visually that the proposed location of lanes corresponds to the

lanes you wish to include in the setup.

3. Click the Zone Setup buttons to add or delete zones until desired number and position are

left.

4. Zones can be added or deleted in Fine Tune later as well.

5. Click the Continue Wizard button again to complete the setup.

Chapter 3 G4 Software

Final Setup:

The Wizard continues the automatic setup to a final Zone Setup unless stopped by clicking the

Pause button. (You can click the Pause button to avoid contaminating the process if traffic

slows down momentarily or there is a large gap in the traffic flow.)

On completion, the final positions of the detection zones will be displayed.

Watch the vehicle icons on the right side of the screen and look for possible "Splashing" of

vehicles in one lane into another adjacent lane also. (Trucks are responsible for most

"splashing".)

Chapter 3 G4 Software

How to Fix Splashing

Splashing occurs when a vehicle from one lane triggers a detection in another lane. Lane

changes are one cause of splashing. Narrow lanes or incorrect boundaries are other common

causes.

1. Start the WinRTMS software.

2. Select Manual Settings from the listed options.

3. Select Zones from the listed options.

4. Select Fine Tune from the listed options.

5. To fix splashing, select a Zone No. and boundary between zones by using left click or

SPACE.

6. Use the Move Away and Move Closer buttons to change the boundary by a single micro

slice at a time. Observe the effect on detection on the Fine Tune or Manual Setup Screen.

 The boundary move affects the zones on either side, reducing one and enlarging the

other.

 A counter shows the amount of shift at any time. This counter resets when you select

the next boundary.

 By selecting Add/Remove Zone button you can change the number of zones and

create wider zones spanning more than one lane.

 The same two mechanisms allow you to perform the entire zone setup process

manually, by adding zones and moving their boundaries manually.

Chapter 3 G4 Software

How to Adjust Sensitivity

Sensitivity adjustments may be necessary to detect small vehicles, or to reduce splashing.

1. Start the WinRTMS software.

2. Select Manual Settings from the listed options.

3. Select Sensitivity from the listed options.

 Increase sensitivity (if needed) to detect small vehicles.

 Reduce sensitivity if the button turns red. (Sensitivity is too high.)

 Adjust sensor aim if small vehicles in close or far lanes are missed. Tilt the sensor

towards the zones with poor detection.

 Do not increase sensitivity to compensate for improper aiming.

Chapter 3 G4 Software

How to Verify Counts

The verification of a good zone setup is an essential part of the installation. In it we compare

RTMS volume measurements over a period of time to a manual (visual) count for the same

interval. Use of a hand-held tally counter is recommended.

1. Start the WinRTMS software.

2. Select Manual Settings from the listed options.

3. Select Verify from the listed options.

4. Select which lanes you wish to verify by checking their adjacent boxes. Unchecked lanes

will remain unchanged.

5. Clear the checked RTMS data counters by clicking the Clear Selected button or by

clicking Clear All.

6. In the selected lanes, count vehicles as they cross the RTMS beam starting immediately

after hitting the Start button.

7. Several observers may be enlisted in the process, with each observer counting traffic in a

different lane. The RTMS Count for each selected lane (zone) will be updated as vehicles

pass.

8. Continue counting until each lane has a count of about 50 vehicles; this will usually take

several minutes. An Elapsed Time counter shows you the interval.

9. Click the STOP button when there is a gap in the traffic and immediately stop your

manual counting on all lanes.

10. Highlight a Manual Count box and enter the manual count for the zone in the

corresponding box.

11. The difference between the RTMS and the manual counts in absolute and percent

deviation terms is immediately displayed. Deviation of more than 5% requires zone setup

correction to improve detection accuracy. The verification process should then be repeated.

12. To save the accumulated results of verification in a text file, click Save to File. Use

normal Windows procedures to name and save the file using the Save As dialog. Similarly

click View File to be shown verification results previously saved.

Chapter 3 G4 Software

How to Modify Vehicle Classifications

The correct classification of vehicles by length requires good breakpoints.

1. Start the WinRTMS software.

2. Select Manual Settings from the listed options.

3. Select Advanced from the listed options.

4. Select Classification from the listed options.

 The Classification screen allows the editing of the five length breakpoints above Small

vehicle: Reg, Med, Large, Truck and XLong.

 For best results, ensure that differences between length breakpoints are greater than 10

ft (3 m) especially for larger vehicles. Small separation values increase potential for

"merging" of classes (vehicle counting errors are the result).

 To check the correctness of the breakpoints, start the per vehicle class counter and

compare the accumulated per vehicle classification counts to manual counts for a

period of at least one minute at a time.

 To select the number of classes, go to Message Composition in Manual Setup.

How to Perform Automatic Speed Calibration

Automatic Speed Calibration is intended for use with higher volume traffic, flowing at stable

speeds.

1. Start the WinRTMS software.

2. Select Speed Calibration from the listed options.

3. Use the Up/Down arrow keys to highlight the per-lane Reference Speeds.

The Left/Right arrow keys will decrease or increase the reference in 2 MPH / km/h

increments, which may be estimated or measured (For example: using a radar gun).

4. Click the Time Indicator and increase or decrease the calibration time with the Right and

Left arrow keys. A minimum of 2 minutes is required, although 3 to 5 minutes is better,

depending on traffic volume. The internal speed coefficients will not update if traffic is too

light.

5. Click the Start button and wait as the lane speeds change from their current level towards

the Reference Speeds.

6. You can click the Pause button to avoid contaminating the process if traffic slows down

momentarily or there is a large gap in the traffic flow. You can then Resume. This is

particularly handy when calibrating mid-block applications. You can also change the

Reference Speed during calibration, if more than 2 minutes are remaining. If after

sufficient time the difference to the reference speed is still more than 10%, manual

adjustment may be necessary.

7. Click on Manual if necessary.

8. Click Exit when you are finished.

Chapter 3 G4 Software

How to Perform Manual Calibration

Manual Speed Calibration is intended for very low-volume traffic (For example: traffic volume

of less than 5 vehicles per minute).



Note

To adjust the speeds after Automatic Speed Calibration, DO

NOT load defaults.

 ONLY Increase or decrease zone speeds as necessary

 It is always best to use Auto Speed Calibration first.

If Not:

 You can Load Default parameters and then observe the

actual reported average speed per lane.

 Compare the displayed speed measurement to your

estimated average speed in each lane.

1. Start the WinRTMS software.

2. Select Speed Calibration from the listed options.

3. Use Up/Down, Left/Right arrow keys to select a zone and adjust up or down in 2 MPH or

km/h increments; as an example, if speed readings are 10 MPH too low, increase that

lane's speed by 10. The new coefficients take effect immediately.
