Chapter 1: Introduction

General

The Autoscope RTMS Sx-300 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 Autoscope RTMS Sx-300 can monitor traffic in up to 12 lanes. The

Autoscope RTMS Sx-300 can be mounted on road-side poles and aimed perpendicular

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 communication

interfaces. Note, other data is also available, for a full list, see “Define Message

Composition” on page 4-20.

The Autoscope RTMS Sx-300 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 Autoscope RTMS Sx-300 to detect stationary and

moving vehicles in multiple detection zones. When pointed onto a roadway, the

Autoscope RTMS Sx-300 microwave beam projects an oval footprint. Its range is

divided into multiple micro-slices, in which vehicles are detected.

The Autoscope RTMS Sx-300 receives reflected signals from all surfaces within its

beam; pavement, barriers, vehicles and trees. 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.

Figure 1-1: Beam Range and Micro-Slices

Multiple operating modes optimize internal parameter settings for highway (mainly

free flowing traffic) and urban (mainly congested traffic) applications. A user can

select how the Autoscope RTMS Sx-300 is configured by setting these modes in the

Autoscope RTMS Setup Utility.

Chapter 1: Vehicle Detection

For mounting:

•The Autoscope RTMS Sx-300 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.

*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 Autoscope RTMS Sx-300 tends

to be less accurate under very low speed conditions.

•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.

•Large trucks may occlude smaller vehicles. If there is a high number of trucks

in traffic, the potential of occlusion increases, which may affect accuracy.

•For more information about our installation, surveying, and training

programs, contact your Autoscope RTMS Sx-300 sales representative.

Pre-Installation Considerations

The following information on power, cabling and communications should be taken

into consideration prior to installing the Autoscope RTMS Sx-300.

Power Considerations

The Autoscope RTMS Sx-300 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 the correct ranges to operate the Autoscope RTMS

Sx-300. The voltage must be between 12 and 24 volts (DC or AC RMS) with the

voltage level read at the Autoscope RTMS Sx-300. Voltages below 12 volts will be

insufficient to power the Autoscope RTMS Sx-300; voltages above 24 volts will cause

the Autoscope RTMS Sx-300 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.

Chapter 2: Pre-Installation Considerations

Current in sufficient quantity must be available: at 12 volts, the Autoscope RTMS

Sx-300 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 Autoscope RTMS Sx-300 will be

12*0.1 = 1.2 watts, or roughly 40% of the power needed to turn on the Autoscope

RTMS Sx-300.

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

Autoscope RTMS Sx-300 to sense an overvoltage condition and shut down to protect

itself.

If additional hardware (such as optional communications modules) is added to the

Autoscope RTMS Sx-300, the power required to operate the Autoscope RTMS Sx-300

will increase. The voltage seen by the Autoscope RTMS Sx-300 will remain the same,

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

Cabling Considerations

The design of an Autoscope RTMS Sx-300 installation should include a breakout box

close to the Autoscope RTMS Sx-300 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. For additional information see

Appendix A: “Cabling and Connectors” and Appendix B: “Surge Protection”.

Communications Considerations

The communication method that comes standard on all Autoscope RTMS Sx-300

units is serial, which can be configured for RS-232 or RS-485 and Bluetooth. Port 1 is

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

to also communicate with the outside world (for a complete list, see “Autoscope

RTMS Sx-300 Options” on page 1-3).

It is recommended that serial port 1 be accessible to field technicians for maintenance

purposes, even if the primary communication with the Autoscope RTMS Sx-300 will

use Port 2.

IMPORTANT: The serial port can support hardware handshaking. It is critical that

hardware handshaking (RTS/CTS) not be enabled by the software if

the corresponding wires are not installed in the cable. Enabling

RTS/CTS without the wires being in the cable will prevent the

Autoscope RTMS Sx-300 serial port from communicating.

Chapter 2: Placement in Side-Fired Highway Configuration

Placement in Side-Fired Highway Configuration

Autoscope RTMS Sx-300 is designed to mount on existing poles and road structures.

Figure 2-1 shows typical cases of Autoscope RTMS Sx-300 side-fired/highway sites.

The design considerations for each case are:

•Case 1 — Maximal utilization of the Autoscope RTMS Sx-300 zone

capability. Limitations are as follows:

– A 12-zone coverage requires a larger setback (the distance to the first

lane. If setback is insufficient, two Autoscope RTMS Sx-300 units may be

required (see “Height and Setback Requirements” on page 2-5).

– Limitations in mapping range slices to lanes will cause decreased

accuracy. The site designer must weigh the trade-off between required

level of accuracy and cost.

– In almost all cases, the Autoscope RTMS Sx-300 can resolve the barrier

return signal from that of the vehicles in the lane immediately behind it as

long as 50% of vehicle can be seen (see “Guardrails and Barriers” on

page 2-8).

•Case 2 — Overpass installations: Do not mount the Autoscope RTMS Sx-300

on a perpendicular overpass. Instead, use poles located at least 5 m (17 ft)

from the overpass to avoid multi-path. Multi-path is a situation in which the

reflected signals from vehicles can also reach the Autoscope RTMS Sx-300

by a secondary reflection from a large flat surface (such as a sign or overpass).

If the overpass is at an angle to the road, take advantage of the angle to point

the Autoscope RTMS Sx-300 at the monitored roadway and away from the

overpass. Do not aim the beam under it.

•Case 3 — Using median poles to mount two Autoscope RTMS Sx-300

sensors, one per direction may save poles but the designer should verify

available set-back (see “Height and Setback Requirements” on page 2-5).

•Case 4 — Sign-structure installations (see “Installing Autoscope RTMS

Sx-300 on Sign Structures” on page 2-10).

•Case 5 — Typical ramp metering site.

Chapter 2: Placement in Side-Fired Highway Configuration

Figure 2-1: Autoscope RTMS Sx-300 Side-Fired Highway Sites

Setback

Chapter 2: Placement in Side-Fired Highway Configuration

Height and Setback Requirements

The Autoscope RTMS Sx-300 has a detection area of 76 m (250 ft), and is able to

detect up to 12 lanes of traffic within that distance. Make sure that all lanes of traffic

are within 76 m (250 ft) of the Autoscope RTMS Sx-300.

Setback is the distance between the nearest edge of the first lane of traffic to be

monitored and the front of the structure on which the Autoscope RTMS Sx-300 is

mounted. Setback is a limiting installation parameter of the Autoscope RTMS Sx-300.

More lanes can be covered with a larger setback.

Zero Setback The Autoscope RTMS Sx-300 has the ability to detect vehicles in lanes with zero

setback, i.e., pole location immediately beside the first lane of detection. Many

Midblock detection sites, as well as bridges, have limited setback.

Figure 2-2: Zero Setback

Zero setback operation is limited to a maximum of four lanes and the mounting height

would be approximately 4 m (14 ft).

It is always recommended to obtain as much setback as possible as this may improve

the overall detection. The zero setback feature is available with all RTMS Sx-300

units and should only be used if the situation dictates. Where significant setback is

available please refer to the standard installation charts.

Standard Setback The Autoscope RTMS Sx-300 should be mounted at a minimum height of 5 m (17 ft)

to minimize occlusion of vehicles even by the tallest trucks.

It must be set back from the first monitored lane to ensure it includes all required lanes

within its field of view. The amount of setback varies with the width of the road to be

covered.

Use the diagrams in Figure 2-3, Figure 2-4, and Figure 2-5 to determine the setback

required to monitor a given number of lanes. The correct installation height can be

determined once the setback 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.

Chapter 2: Placement in Side-Fired Highway Configuration

NOTES:

•It is almost always better to be further back from the minimum. If clear space

is available, move the Autoscope RTMS Sx-300 further back.

•The mounting height is based on the setback. Using the correct height value

allows the Autoscope RTMS Sx-300 to be aimed so that it receives maximum

return signal while covering all required lanes. Mounting the Autoscope

RTMS Sx-300 at an incorrect height will reduce accuracy.

•Widths of roadway medians must be included in the total detection area. For

example: You may be able to set up 12 zones, but they must be within 76 m

(250 ft).

Figure 2-3: Autoscope RTMS Sx-300 Initial Aiming

The amount of setback you have will determine your actual detection area. As shown

in Figure 2-2, a setback of 0 to 1.6 m (0 to 5 ft) will allow the Autoscope RTMS

Sx-300 to detect vehicles up to about 15 m (50 ft). A setback of 7 m (23 ft) allows the

Autoscope RTMS Sx-300 to detect vehicles up to 61 m (200 ft) of the Autoscope

RTMS Sx-300.

Chapter 2: Placement in Side-Fired Highway Configuration

Figure 2-4: Setback Distance Chart

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

mounting height based upon actual setback distance.

Chapter 2: Placement in Side-Fired Highway Configuration

Figure 2-6 shows the effect of restricted setback on the number of lanes that can be

monitored by a single Autoscope RTMS Sx-300. Depending on the total area of

detection required and the available setback the need for a second unit may be

required. The same pole can be used to install the unit; however, a minimum of 1 m

(3.3 ft) is required between the units.

Figure 2-6: Effect of Low Setback

Guardrails and Barriers

In almost all cases, median guard-rails or barriers do not interfere with traffic

detection. In the few cases in which such interference may occur, e.g., large metal

barrier, very tall barriers or movable metal fences, a good solution is to use a second

sensor on the other side of the road. Each of the sensors can monitor lanes on its side

of the barrier, requiring a smaller setback to cover fewer lanes, as shown below.

Figure 2-7: Two-Sided Placement

Chapter 2: Placement in Side-Fired Highway Configuration

Elevated Roadway

On elevated or sunken roadways with insufficient outside shoulders, it may be an

impossible job for a single sensor. Two Autoscope RTMS Sx-300 units, configured as

shown by Figure 2-8, will cover all lanes if detection zones are defined as shown in

Figure 2-8.

Figure 2-8: Autoscope RTMS Sx-300 on Elevated Roadway

Autoscope RTMS Sx-300 can also monitor elevated highways from tall poles erected

on the lower level. However, in this case the setback should be less than 8 m (26 ft), to

avoid the strong reflection from the side of the structure.

Figure 2-9: Pole Location for an Elevated Roadway

Chapter 2: Placement in Side-Fired Highway Configuration

Sunken Road and Roadside Walls

When vertical surfaces reflecting microwaves (e.g., dense chain link fences or

retaining walls of a sunken roadway) are present, multi-path reflections from large

vehicles in close lanes cause additional false (ghost) detection in farther detection

zones.

Figure 2-10: False Target Generated by Fence Or Wall

To avoid this problem install the Autoscope RTMS Sx-300 higher and increase the

elevation angle to detect the far lanes of traffic excluding the nearest lanes, as shown

on the right in Figure 2-10.

Installing Autoscope RTMS Sx-300 on Sign Structures

The installation of the Autoscope RTMS Sx-300 on Message Sign structures is

acceptable only if the Autoscope RTMS Sx-300 is mounted to be offset from the

overhead span of the structure. Structures can reflect the microwave signal and distort

the accuracy of detection. Some structures such as DMS units have very wide, flat

metal bottoms to the structure that are similar in nature to bridges, these type can

cause more interference than other lattice work type structures and may require

consultation with Autoscope RTMS Sx-300 Technical Support.

The best way to mount the Autoscope RTMS Sx-300 is to place a horizontal mast arm

or pipe approximately 1.3 m (4 ft) away from the structure (1.8-2.4 m [6-8 ft] if

DMS), ideally on the back of the structure away from any lighting or signs. Ensure the

detector is aimed perpendicular to the traffic flow.

Figure 2-11: Autoscope RTMS Sx-300 on Sign Structures

Chapter 2: Placement in Side-Fired Highway Configuration

Grade Differentials

When grade differences are small, a single unit on the high side may work, provided

all lanes are within range.

Figure 2-12: Small Grade Differentials

When the grade differential is large enough to put a part of the lower level in a

“shadow”, two Autoscope RTMS Sx-300 units are required as shown by the

following.

Figure 2-13: Large Grade Differential

Trees

Trees and bushes in the path of the microwave beam (in the setback or in medians)

must be avoided. Autoscope RTMS Sx-300 units must be relocated or a gap in

vegetation maintained in the path of the beam.

Chapter 2: Placement in Midblock Applications

Placement in Midblock Applications

Placement in Midblock application is similar to Side-fired Highway. If sufficient

setback is available, up to 12 zones of traffic can be configured. If the Autoscope

RTMS Sx-300 is mounted in a zero setback configuration, only the nearest four zones

are available for detection; however, the nearest zones can be excluded from detection

(creating adequate sensor setback) if data from zones farther away is desired. The

installer should verify which intersection approaches are most critical to proper data

collection and configure the Autoscope RTMS Sx-300 to capture information from

these lanes of traffic.

Figure 2-14: Midblock Placement

Mounting and Aiming Procedure

Chapter 4: Configuration and Setup

General

This chapter describes the procedures for configuring the Autoscope RTMS Sx-300

system using the Autoscope RTMS Setup Utility.

Configuration Process

After the Autoscope RTMS Sx-300 hardware and software are installed (see Chapters

2 and 3), you must set up and configure each of the Autoscope RTMS Sx-300 units in

the system.

The configuration process requires you to physically connect the computer where the

Autoscope RTMS Setup Utility is installed to each Autoscope RTMS Sx-300 in the

system. Once connected, you must start the Setup Utility (see “Starting the Setup

Utility” on page 3-7).

Each Autoscope RTMS Sx-300 must be set up (configured) according to the following

eight step process.

•Step 1:Set the Application Mode

•Step 2:Run the Wizard

•Step 3:Adjust the Zones

•Step 4:Verify Vehicle Counts

•Step 5:Calibrate Speed

•Step 6:Define Message Composition

•Step 7:Define Vehicle Classifications

•Step 8:Save the Configuration File

After the Configuration process is completed, you can adjust the Autoscope RTMS

Sx-300 setup as needed for your site. For more information see Chapter 5: “Operations

and Adjustments”.

Required Equipment/Personnel

The following equipment and personnel will be needed in order to perform the

configuration process.

•At least two persons

•A hand-held tally counter

•Light Detecting and Ranging (LIDAR) radar gun

•Speed calibration worksheet (see Appendix E: “Speed Calibration

Worksheet”)

•Stop watch

Chapter 4: Required Equipment/Personnel

Step 1: Set the Application Mode

You must define whether the Autoscope RTMS Sx-300 is to operate in a Side-Fired or

Midblock application.

1. On the Main Screen, click Manual Settings.

The following screen appears.

2. Click Application =.

Chapter 4: Required Equipment/Personnel

The following screen appears.

3. Select the application the Autoscope RTMS Sx-300 will be used for.

•Side Fired Highway — in general, used when:

– traffic is mainly free-flowing

– farther detection distance needed

– lanes are wide

•Midblock — in general, used when:

– traffic is mainly urban (can be congested)

– shorter detection distance needed

– lanes are narrow

Chapter 4: Required Equipment/Personnel

NOTES:

•Click on the application to be used even if it already appears to be selected.

This will ensure that all settings are sent to the Autoscope RTMS Sx-300.

•If you get a message indicating that the application requires a new wizard

setup, click Yes.

4. To return to the Main Screen, click Exit.

5. Continue with “Step 2: Run the Wizard” on page 4-5.

Chapter 4: Required Equipment/Personnel

Step 2: Run the Wizard

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

It scans the range of the Autoscope RTMS Sx-300 microwave beam and positions up

to 12 detection zones, representing lanes where vehicles are detected.

The Autoscope RTMS Setup Utility automatically detects traffic in its detection area

and configures lane parameters accordingly. This is a two-stage process.

•Initial setup: The Wizard finds zones which match up to the lanes of traffic.

•Final setup: The Wizard fine tunes the zone boundaries and detection

parameters.

NOTE: You may receive warnings while detecting traffic in low-volume lanes. The

warning asks if you would like to continue detection for one additional

minute. If the sensor is installed where it detects both mainline and secondary

zones such as ramps or frontage roads, these potentially low-volume zones

can be ignored if desired. Extending the wizard setup for the benefit of the

secondary zones is not necessary.

1. On the Main Screen, click Wizard Setup.

The following screen appears.

Chapter 4: Required Equipment/Personnel

Step 4: Verify Vehicle Counts

The vehicle count verification of a successful zone setup is an essential part of the

installation. During the process you will compare Autoscope RTMS Sx-300 volume

counts over a period of time to a manual (visual) count for the same interval. Use of a

hand-held tally counter is recommended.

IMPORTANT: The recommended and most accurate method of verifying vehicle

counts is to perform the verification individually on each zone.

However, if a sufficient number of personnel are available, all zones

can be verified simultaneously. This alternate process requires at

least one person per zone for manual count purposes.

1. On the Main Screen, click Verify Counts.

The following screen appears.

Chapter 4: Required Equipment/Personnel

2. Are you verifying counts for a single zone or for all zones?

The elapsed time counter starts automatically, and the count for each selected zone

is updated as vehicles pass.

3. Continue counting until a minimum of 50 vehicles (more than 50 is

recommended) have been counted for the zone being verified. This will usually

take several minutes.

4. Click Stop when there is a gap in the traffic and immediately stop your manual

counting.

5. Select the box in the Manual column and enter the manual count for the zone.

Single Zone All Zones

a) Select the check box to the left of

each zone.

b) Click Clear Selected and

immediately begin counting

vehicles as they cross the

Autoscope RTMS Sx-300 beam.

NOTE: There must be one person

per zone.

begin counting vehicles as they cross

the Autoscope RTMS Sx-300 beam.

Chapter 4: Required Equipment/Personnel

The difference between the Autoscope RTMS Sx-300 and the manual counts in

difference and percentage deviation is immediately displayed. Deviation of more

than 5% requires zone setup correction to improve detection accuracy.

If the Autoscope RTMS Sx-300 count is greater than 5% of the manual count, this

could be caused by:

– Splashing” (vehicles in one zone are shown as being detected in an

adjacent zone)

– Lane changing

– Reflections from fixed objects

– Sensitivity set too high

Chapter 4: Required Equipment/Personnel

If the Autoscope RTMS Sx-300 count is less than 5% of the manual count

(negative percentage), this could be caused by:

– Missed small vehicles (sensitivity is too low)

– Occlusions

– Incorrect aiming

6. Are any of the percentages over five percent (either plus or minus)?

7. (Optional) If you want save the accumulated results of verification in a text file,

click Save to File.

The following window appears.

Yes No

You should make corrections before continuing. See

“Optimizing Volume Count Accuracy” on page 5-34.

12. Continue with “Step 5: Calibrate Speed” on page 4-15.

Chapter 4: Required Equipment/Personnel

Step 5: Calibrate Speed

Speed calibration is a three step process that requires the following to be performed:

•Setting up the reference speed

•Running the automatic calibration

•Checking the calibration

In order to perform the speed calibration process, the following is required:

•Light Detecting and Ranging (LIDAR) radar gun or a similar device

•Speed calibration worksheet (see Appendix E: “Speed Calibration

Worksheet” or the online version in the Autoscope RTMS Sx-300 help files).

•Two people

NOTES:

•Prior to performing any speed calibration on the Autoscope RTMS Sx-300,

ensure that the volume accuracy has been optimized. This will enable the

speed calibration to proceed smoothly and provide quality results.

•Speed calibration should be performed when traffic is moving at the posted

Chapter 5: Message Operations

Message Operations

There are three different operations that have an effect on the messages that are sent

by the Autoscope RTMS Sx-300 sensor:

•Defining the message composition

•Defining per vehicle messages

•Changing the frequency at which messages are sent

Defining the Message Composition

This operation defines the format of the statistical message (G4 or X3) and what data

is to be included in the message. For information about setting the composition of the

message, see “Step 6: Define Message Composition” on page 4-20.

Defining Per Vehicle Messages

When the Per Vehicle option is turned ON, a message is sent for every vehicle when it

is detected.

In the data file (see Appendix C: “Data Files and Message Formats”) the per vehicle

data is listed between the statistical messages that are sent for each message period

(see Figure C-4 on page C-5). The per vehicle data will add up to the same values that

are listed in the statistical message.

When Per Vehicle is ON, the per vehicle data is sent in between the regular statistical

messages. The data provided is as follows:

•Autoscope RTMS Sx-300 ID - ID number assigned to the sensor

•Lane - the zone where the vehicle was detected

•Class - the vehicle classification (small, medium, truck, etc.)

•Speed - the detected speed of the vehicle

•Length - the length of the vehicle

•Dwell - amount of time, in milliseconds, the vehicle is being detected

NOTE: If the Autoscope RTMS Sx-300 sensor is set to polled mode (see “Changing

the Data Mode” on page 5-2) with Per Vehicle turned ON, there will not be

any per vehicle data available in the live data stream. However, the per

vehicle data is available from internal memory downloads if the Store Into

Memory function is enabled (see “Defining Memory Options” on page 5-25).

To enable the Per Vehicle option, do the following.

1. On the Main Screen click Per Vehicle to turn the option ON or OFF.

Chapter 5: Message Operations

When the option is turned ON, the following window appears.

2. Click Ye s to enable (turn ON) the Per Vehicle option, or No to cancel the

operation.

Chapter 5: Message Operations

Changing the Message Period

The message period is the amount of time between sending statistical reports from the

Autoscope RTMS Sx-300. When the system is set up, a default period of 30 seconds is

used. This is the message period generally used for Real-Time traffic data. A 300 to

900 second period (5 to 15 min) is recommended for counting applications.

To change the message period, do the following.

1. Start the utility (see “Starting the Setup Utility” on page 3-7).

2. On the Main Screen, click Manual Settings.

3. On the Manual Setup screen, click Message Period.

The following screen appears.

Chapter 5: Optimizing Volume Count Accuracy

4. Click the Up and Down arrows or use the arrow keys on your computer to set

Message Period to the desired interval.

For G4 STAT protocol the range is 5 to 3600 seconds. For X3 STAT protocol it is

5 to 900 seconds.

5. To synchronize the message with the Autoscope RTMS Sx-300 clock, select the

Sync check box.

Example: If the message period is set to 30 seconds, the message will be sent out

at 00:00:00 and 00:00:30; not at 00:00:03 or 00:00:33.

Note, this feature synchronizes the Autoscope RTMS Sx-300 clock and message

period with the connected PC. The program must be running to synchronize

Autoscope RTMS Sx-300.

6. Click OK.

The new value is set and you are returned to the Manual Setup screen.

Optimizing Volume Count Accuracy

The most common reasons for vehicle count discrepancies are:

•Zone boundaries overlap or are too close – When this occurs, vehicles in one

zone are shown as being detected in an adjacent zone. This is referred to as

“splashing.” In this case, changing the zone by increasing or decreasing the

boundary by one or more micro-slices can eliminate splashing.

•Improper sensor aiming – When this occurs vehicle counts are below what is

expected. If the sensor is aimed too low or high, or is not perpendicular to the

zone, vehicles may not be detected.

•Sensitivity too high or low – If the sensor is correctly aimed, incorrect counts

could be caused by an improper sensitivity setting.

•Obstruction between the sensor and zone – An obstruction, such as a concrete

lane divider may cause smaller vehicles to be missed.

•Occlusion – This is when a vehicle is hidden from view by another vehicle or

object. A large truck can occlude (hide) the detection of a small car hidden

behind.

The following provides information about the possible cause and solution for various

conditions that can cause inaccuracies in the volume count.

Chapter 5: Optimizing Volume Count Accuracy

Condition A: Over/Under Count in Adjacent Zones

In the situation shown in Figure 5-3, zone 2 shows an over count, while zone 3 shows

and under count.

Figure 5-3: Over/Under Count: Adjacent Zones

The above could indicate that vehicles from zone 3 are being detected in zone 2. Fine

tune the zone boundary between the two zones by one micro-slice to begin with

(Move Closer –1). See “Adjusting Zone Boundaries” on page 5-55. Recheck the

results and adjust further if needed.

Chapter 5: Optimizing Volume Count Accuracy

Condition B: Under Count in Near Zone

In the situation shown in Figure 5-4, the count for zone 1 is well below what is

expected; vehicles are being missed.

Figure 5-4: Under Count: Near Zone

The above is probably due to aiming issues. The sensor may be missing small profile

vehicles. Check the aiming of the Autoscope RTMS Sx-300 and make sure it is aimed

down enough to view the first lane of traffic (zone 1).

Chapter 5: Optimizing Volume Count Accuracy

Condition C: Under Count in Far Zone

In the situation shown in Figure 5-5, the count for zone 8 is well below what is

expected; vehicles are being missed.

Figure 5-5: Under Count: Far Zone

The above is probably due to aiming issues. The sensor may be missing small profile

vehicles. Check the aiming of the Autoscope RTMS Sx-300 and make sure it is aimed

up enough to view the last lane of traffic (zone 8).

Chapter 5: Optimizing Volume Count Accuracy

Condition D: Under Count in Several Zones

In the situation shown in Figure 5-6, the count for many zones is below what is

expected; vehicles are being missed.

Figure 5-6: Under Count: Many Zones

In the above situation the signal strength reflection may be too low. This could be

caused could by the following:

•The aiming angle is not perpendicular to the traffic.

•The sensitivity is too low.

Check the aiming angle. If this is OK, then increase the sensitivity (see “Sensitivity

Adjustment” on page 5-47).

Chapter 5: Optimizing Volume Count Accuracy

Condition E: Over Count in Several Zones

In the situation shown in Figure 5-7, the count for many zones is above what is

expected.

Figure 5-7: Over Count: Many Zones

In the above situation the signal strength reflection may be too high, causing

“splashing” into adjacent lanes. The most likely cause is that the sensitivity is too

high. Decrease the sensitivity (see “Sensitivity Adjustment” on page 5-47).

Chapter 5: Optimizing Volume Count Accuracy

Condition F: Under Count in First Zone Past a Barrier

In the situation shown in Figure 5-8, the count for zone 5 is lower than what is

expected.

Figure 5-8: Under Count: First Zone Past Barrier

The above could indicate there is some kind of barrier between zones 4 and 5. The

signal from the barrier is imposing on zone 5, causing smaller vehicles to be missed.

Moving the zone boundary away from the barrier should help resolve this situation.

Fine tune zone 5 by moving the zone boundary closest to the barrier further away from

the barrier (move away +1). An adjustment of 1 or 2 micro-slices can make a large

improvement. See “Adjusting Zone Boundaries” on page 5-55. Recheck the results

and adjust further if needed.

Chapter 5: Polling Sensors

Polling Sensors

This option can be used to verify the operation of a single Autoscope RTMS Sx-300

sensor or multiple Autoscope RTMS Sx-300 sensors that share the same

Zone Setup

After the initial configuration is complete, it may be necessary to add or delete zones,

or to adjust the boundaries of individual zones or sensitivity, such as when “splashing”

occurs or for accommodating wider merge lanes, etc. For information about sensitivity

see “Sensitivity Adjustment” on page 5-47.

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.

Appendix A: Cabling and Connectors

General

Autoscope RTMS Sx-300 units use a single 32-pin MS connector for power and

communications. For information about the MS pinouts, see “MS Connector Pin Out”

on page A-3.

The Autoscope RTMS Sx-300 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 RTMS Sx-300 model.

Table A-1: Required Wiring Pairs

Model Number of Pairs

RTMS Sx-300 (Base Unit) Standard RS-232/485 plus power: three pair

If using RTS/CTS option for RS-232: four pair

If using RS-485: four pair

RTMS Sx-300 TCP (Base Unit plus TCP/IP) Two additional pair

RTMS Sx-300-SSP (Base RTMS Unit plus

Second Serial Port)

If using without RTS/CTS option for RS-232: one additional

pair

If using RTS/CTS option for RS-232: two additional pair

If using RS-485: two additional pair

Contact Closures: The Sx-300 SSP model has

built in Contact Closures. If you are utilizing

them you will need:

Eight additional pair. Note, Up to eight additional only if all

Contact Closures are used.

Preparing a Cable

Use cable such as the Belden number 951x (1x indicates number of pairs). For

example: 9516 is a 6-pair cable. In preparing a cable note the following:

•Use the Connector Kit from ISS to match the product:

– For Sx-300 base system use RTMS CNSET RS232 per ISS Part Number

A750-1146

– For Sx-300 TCP use RTMS CNSET RJ45 per ISS Part Number

A750-1153

– For Sx-300 SSP use RTMS CNSET RS232 per ISS Part Number

A750-1149

– For Sx-300 SSP-CC use RTMS CNSET RS232 per ISS Part Number

•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.

•The Daniels Manufacturing Corporation crimping tool M22520/1-01 AF8

with head number M22520/1-02 or equivalent is recommended.

•Do not solder MS connector pins to the cable. They must be properly

crimped.

The following table lists the maximum length of the cable based on the type.

Table A-2: Max Cable Length

Protocol Max Cable Length

RS-232 For baud rate of 19,200 or 115,200: 15 m (50 ft)

For baud rate of 9600: 152 m (500 ft) is the recommended

maximum. However, you can go up to 244 m (800 ft) when

the:

•Cable has a minimum gauge of 20 AWG

•Baud rate is 9600

•Environment is ideal

•Cable is continuous

RS-485/RS-422 1219 m (4000 ft) for all baud rates.

TCP/IP over CAT 5 91 m (300 ft)

Connecting a Cable to the Autoscope RTMS Sx-300

To connect a cable to the Autoscope RTMS Sx-300 device, do the following.

1. Thread the 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 Autoscope

RTMS Sx-300 data together with manual counts.

Surge Suppression/Protection

Each Autoscope RTMS Sx-300 unit has built-in surge-suppression hardware. For

complete information see Appendix B: “Surge Protection”

Wiring Notes

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

disconnecting the Autoscope RTMS Sx-300 from the transmission line for direct

connection to the laptop's COM port for setup.

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

and Transmit transmission pairs.

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.

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

not standardized and vary between models.

MS Connector Pin Out

Pin labeling in Figure A-1 is a guideline only. Verify pin location on actual connector

before inserting wire.

NOTES:

•The Autoscope RTMS Sx-300 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.

Take note of the individual wiring instructions provided in this manual.

•Connect the cable’s shield (drain wire) to pin U at the MS connector.

The Autoscope RTMS Sx-300 comes with a Serial Port that can be configured as

RS-232 or RS-485. For information about how to set the communications

configuration, see “Defining Communications” on page 5-7.

Standard RS-232 Port Wiring

The standard Autoscope RTMS Sx-300 RS-232 port wiring consists of Transmit (Tx),

Receive (Rx), Request to Send (RTS), Clear to Send (CTS) and Ground lines wired to

the MS pins respectively. The use of a female DB9 connector and wiring shown

allows the use of standard serial cable for direct connection to the PC for setup

purposes. For the maximum cable length, see Table A-2 on page A-2). Rear views of

connectors are shown to assist in cable preparation. The Autoscope RTMS Sx-300 is

RS-485 Port Wiring

There is no standard pin configuration for RS-485 on a DB9 connector.; so we suggest

the following configuration. The wiring diagram shown will connect directly to a

RS-232 configured DB9 without the need for an RS-232/RS-485 converter. The

maximum cable length is 1219 m (4000 ft). Over short distances (9 m [30 ft]) the

wiring diagram shown below is compatible with an RS-232 port.

A disconnect point is recommended to allow the Autoscope RTMS Sx-300 to be

detached from the transmission line without disruption of communications with other

sensors on the line. See “Connecting Autoscope RTMS Sx-300 to External Modems”

on page A-7 for details.

RS-485 Multi-Drop Wiring

The RS-485 setting of the Autoscope RTMS Sx-300 Serial Port allows up to 32

Autoscope RTMS Sx-300 units to be employed on the same serial bus over distances

up to 1219 m (4000 ft).

RS-485 is used for multipoint communications. This allows more devices to be

connected to a single cable, similar to an Ethernet network which uses a coaxial cable.

Most RS-485 use a Master/Slave architecture, where each slave unit has its own

unique address and responds only to packets addressed to it. The packets are generated

by a master (e.g., PC) which periodically polls all connected slave units.

The following diagram shows the use of a 4-Wire line. Note, a 2-wire line is not

recommended or supported.

Figure A-4: RS-485 Multi-Drop Wiring

Connecting Autoscope RTMS Sx-300 to External Modems

The Autoscope RTMS Sx-300 may be connected to a remote traffic data collection

system over private telephone lines using modems. Multiple Autoscope RTMS

Sx-300 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.

Autoscope RTMS Sx-300 sensors are deployed in locations where the quality of

power lines can be questionable. Industrial machinery and environmental factors can

cause excess noise and voltage/current spikes on power lines. Additionally, poor

grounding of equipment can amplify the effects of these disturbances. It is

recommended that all lines connected to the Autoscope RTMS Sx-300 sensor (i.e.,

power and communication) have surge protection and each sensor be sufficiently

grounded as outlined in this appendix.

The purpose of this appendix is to provide an understanding of why proper grounding

and surge protection is important to a successful Autoscope RTMS Sx-300 sensor

deployment and provide guidelines for grounding of equipment and installing surge

protection devices to protect each Autoscope RTMS Sx-300 sensor.

Breakout Boxes

Every sensor should have a breakout box on the same pole that the Autoscope RTMS

Sx-300 sensor is mounted (see Figure B-1). The breakout box should be no more than

6 m (20 ft) from the Autoscope RTMS Sx-300 sensor (see Figure B-1).

Figure B-1: Typical Installation

Each breakout box should contain a manufacturers approved surge suppression

package, which includes a power supply and all the necessary surge protection

devices.

Parts of the Surge Suppression Package

Cabling to the Breakout Box

The Mains power should enter the breakout box and go directly to the surge protection

package as described in the wiring diagram provided with the package. The earth

ground wire from the Mains power should tie to the breakout box, the surge protection

package, and directly to the grounding rod as described in “Grounding” on page B-5.

IMPORTANT: The Mains earth ground conductor MUST come with the Mains

power conductors from the utility. The local ground rod is only for

suppression of surge and must be tied to the earth ground reference

from the power source.

Cabling From the Breakout Box

The only cable leaving the breakout box should be the low voltage power cable going

directly to the sensor.

IMPORTANT: The cable from the breakout box to the Autoscope RTMS Sx-300

sensor should be routed up the pole directly to the sensor and should

not share conduits with or be routed next to high voltage/high

current (AC or DC) power lines.

Parts of the Surge Suppression Package

Power Line Protection

The first part of a surge suppression package is providing a barrier between the

incoming power lines and the power provided to the Autoscope RTMS Sx-300 sensor.

A circuit breaker (CB) and a power transient suppressor (PTS) provide this protection.

The incoming power line should go through the circuit breaker, then to the PTS

device. In this configuration, if a surge occurs the PTS will shunt excessive current to

earth ground and subsequently trigger the CB. This opens the circuit and prevents

damage to the sensor and the PTS. The CB must have a 2A rating.

IMPORTANT: The negative terminal of the low voltage side of the power supply,

battery, or solar controller must be connected to the earth ground in

order to provide a reference point for the Autoscope RTMS Sx-300

built-in surge protection.

Communication Line Protection

Communication lines to the Autoscope RTMS Sx-300 sensor are sensitive lines that

must be protected from external influences to prevent damage to the communication

interface on the sensor and ensure uncorrupted data flow to and from the sensor. Each

communication line should be protected by a device that will shunt excess current on

the line to earth ground rather than sending that current through the Autoscope RTMS

Sx-300 sensor and causing damage to the device. Care must be taken when providing

protection on communication lines to ensure the device chosen will not add excess

capacitance or inductance that could cause disruptions to the integrity of the data.

Figure B-3 and Figure B-4 show the protections provided by the manufacturers

approved surge suppression packages on the communications interfaces for the

Autoscope RTMS Sx-300 sensor.

Grounding

Providing a Proper Ground

Providing a low resistance earth ground connection is essential to achieving effective

surge protection. Total resistance from the protected circuit to the earth should be <5

ohms.

Figure B-5: Earth Ground Connection

A grounding rod (see Figure B-5) should be at least 1.83 m (6 ft) in length and placed

as close as possible to the base of the Autoscope RTMS Sx-300 mounting pole. The

grounding conductor should be flexible copper braid or copper wire 12AWG or larger.

Why Grounding is Important

Figure B-6: Surge Channeled into Earth Ground

The earth grounding rod, together with proper ground of the breakout box, and surge

protecting devices installed in close proximity of the mounting pole, create a barrier or

‘sink hole’ for any charges and surges coming towards the sensor from the

surrounding area (see Figure B-6). These charges and surges may be caused by

industrial noise, power surges, or lightning.

Thunderstorm lightning is in its own class of destructive forces to sensors. Typically, it

can generate 30 to 300 kA of current, far beyond the capabilities of any surge

protecting devices. Therefore, a direct or near direct lightning hit may cause

equipment damage even in the presence of surge/transient protecting devices.

Because lightning is a major influence on power line surge, it is important to

understand the exposure to thunderstorms in the area where the Autoscope RTMS Sx-

300 sensor is being installed. In areas that are exposed to large number of

thunderstorms, protecting sensors will be more challenging.

Mounting pole, sensor

and breakout box

Low Voltage Power

The manufacturers approved surge suppression packages include a 24VDC power

supply. The output of this supply is tied to the cable that powers the Autoscope RTMS

Sx-300 sensor. This cable should not be longer than 6 m (20 ft) in length and should

only be run directly from the breakout box at the mounting pole for each Autoscope

RTMS Sx-300 sensor up the mounting pole to the Autoscope RTMS Sx-300 sensor.

IMPORTANT: The cable from the breakout box to the Autoscope RTMS Sx-300

sensor should be routed up the pole directly to the sensor and should

not share conduits with or be routed next to high voltage/high

current (AC or DC) power lines.

You should not power Autoscope RTMS Sx-300 sensors from low voltage sources

(either AC or DC) over cables longer than 6 m (20 ft) for the following reasons:

•Long low voltage lines act as an antenna for all sorts of disturbances, noise,

and surges.

•Significant power loses can occur at long distances.

•305 m (1000 ft) of typical 18 AWG stranded wire introduces resistance of

about 6.6Ω per wire. The base Autoscope RTMS Sx-300 unit draws 0.25A at

12V. The cable loss can be calculated as:

Vdevice = IRTMS * Rcable = 0.25A * (2 * 6.6Ω) = 3.3 VDC

Note:

Rcable = 2 * resistance per wire because the current travels to the device on the

power wire and returns from the device on the ground wire.

With a cable input voltage of 12 VDC and a 3.3V cable loss, the voltage at the

Autoscope RTMS Sx-300 input will be 8.7V.

This is less than the minimum voltage requirement of the Autoscope RTMS

Sx-300 sensor (12V).

The manufacturer cannot guarantee proper operation of the unit and/or its longevity if

low voltage power over a long line is used to power an Autoscope RTMS Sx-300

sensor, and does not recommend or support providing power in this configuration.

However, the following are some things to help limit the risks.

•Use an isolated 24VDC power source.

•Increase the gauge of the power wires to reduce voltage drop. Reference the

datasheet for the wire you are installing or an American Wire Gauge lookup

table for resistance per foot of each wire gauge.

•Mount low voltage surge protection at the base of the mounting pole and

ensure the protection device has a low resistance reference (<5 ohms) to earth

ground.

•Avoid running Autoscope RTMS Sx-300 sensor cables parallel or close to

high voltage/high current power lines (including in conduits).

Autoscope RTMS Sx-300 Interface Panels

It is recommended that approved interface panels, which include appropriate surge

protection, be used to protect Autoscope RTMS Sx-300 sensors. The approved

interface panels, which include appropriate surge protection, are listed in Table B-8.

The connections for each surge panel is shown in the pages that follow.

Operations

General

IMPORTANT: Bluetooth shares serial port 1 in the Autoscope RTMS Sx-300;

therefore, any physical connection to port 1 must be disconnected so

that communications to the Autoscope RTMS Sx-300 via bluetooth

can be established.

Before you can set up Bluetooth communications with the Autoscope RTMS Sx-300,

use the manufacturer’s instructions to install a Bluetooth device on your computer.

Some computers come with pre-installed Bluetooth capabilities. We recommend that

you determine the specifications of the internal Bluetooth adapter prior to establishing

a link to the Autoscope RTMS Sx-300. Using the internal Bluetooth adapter may not

give you adequate range to establish a reliable link to the Autoscope RTMS Sx-300.

NOTES:

•It is recommended that at least Bluetooth 2.0+EDR Class 1, and strongly

recommends the Sena Parani UD100-G03 USB Bluetooth adapter.

•Bluetooth requires that the baud rate for port 1 in the Autoscope RTMS Sx-

300 be set to 115,200, which is the default setting.

There are three classes of Bluetooth devices. The different classes have different

ranges as follows:

•Class 3 radios – 1 m (3 ft)

•Class 2 radios – 10 m (33 ft): most commonly found in mobile devices

•Class 1 radios – 100 m (328 ft): used primarily in industrial use cases

Bluetooth is not a line-of-sight connection, so it can be used through walls and floors.

However, things such as walls, people, poles and vehicles can reduce the range.

The following sections describe how to locate and connect to a Bluetooth device when

using recommended Sena Parani adapter or through Microsoft Windows.
