8 INSTALLATION GUIDE
8.1 DIRECTION DETECTION
The TMA-3B3 measures in both directions, and associates a + sign to the speed for the approaching objects and a – sign for
the receeding ones. We recommend to install the radar so that the approaching direction is the direction with the largest
volume of cyclists.
8.2 CHOICE OF THE INSTALLATION LOCATION
•The TMA-3B3 is designed to measure on dedicated bicycle paths only. It is not able to count the bicycles in mixed traffic
situations.
•Select a free-flowing section to perform the counting, where targets are not supposed to stop in the sensor beam. Proximity of
intersections is not advised. A bloc of measurements with the same time stamp corresponds to the case where a target
stopped for some time in the "laser" beam. Currently this is not filtered out and generate a "long" target that is then sliced in so
many bicycles.
•The sensor measures both directions. If the bicycle path is one-direction, install the radar in the way it detects the approaching
direction.
•Max. measurement distance of the sensor: about 6 m (angle 45°). This results in a maximum width “D” of 4 m, see Figure 4.
•Max. width of the bicycle path: 4 m, offset included.
•Avoid obstacles like tree branches or leaves in the beam of the sensor.
8.3 PHYSICAL INSTALLATION
•Offset: distance between the pole and the near edge of the bicycle lane (perpendicular to the bicycles direction)
•Distance: distance between the pole and the far edge of the bicycle lane (perpendicular to the bicycles direction).
This distance (D) is equal to the Width (W) of the bicycle path plus the Offset (O)
D = W + O
•Height:distance between the ground and the low edge of the radar bracket

The aim is for the lidar beam to "cut" cyclists at chest height. We therefore recommend installing the radar at a height of 1.4 m
and a vertical angle of max. 5°, i.e. close to the horizontal (see section 8.4 below for precision in function of installation height).
.
1. Horizontal angle: 45° (towards the bicycles direction)
2. Vertical angle (inclination towards the ground): The light emitting beam must “cut” the cyclists, at the waist level or
higher. An installation at 0° (horizontal installation) is possible.
3. Fix the screws.
Figure 4: installation, general overview
Figure 5: installation, side view
8.4 PRECISION IN FUNCTION OF THE INSTALLATION HEIGHT,OFFSET AND WIDTH OF BICYCLE PATH
The higher the radar is installed, the larger vertical angle of the radar to detect the cyclists and therefore the smaller the
detection Distance (D). Figure 6 shows in green the possible combinations of Offsets and Width at installation height of 2 m
for a high degree of precision (97 % or more). The orange area shows the combinations of Offsets and Width for which the
detection precision will drop below 97 %.
The detector beam needs to point towards the head or the body of the cyclists, not the legs. Therefore, when placing the
detector higher, the light beam of the detector needs to be directed towards the ground at a larger angle. The angle and
The cyclists must “cut” the light emitting sensor beam in
order to be detected and counted. Please check the
cyclists, particularly the children, who are riding at the
side where the radar is installed are well detected. If
necessary, reduce the height of installation.

therefore the maximum distance of detection is therefore a function of the height of the installation, the Offset (O) and the
Width (W) of the bicycle path.
The maximum detection Distance D as shown in Figure 4 is 4 m. At an Offset value of zero meter, the maximum width of the
bicycle path is equal to 4 meters, which is in such particular case equal to the maximum Distance D.
Assuming that the minimum height of the saddle is 1m and that the minimum height of the cyclists’ heads is 1.6m, the
maximum Width W of the bicycle path with Offset zero is 1.25 m as shown in Figure 6 for an installation height at 2m.
For an installation height at 2.5m, the maximum Width W of the bicycle path with Offset zero is 0.35 m as shown in Figure 7.
For an installation height at 1.4 m, the maximum Width W of the bicycle path with Offset zero is 4 m as shown in Figure 8.

10 RADAR SETTINGS
10.1 COMMUNICATION
•The TMA-3B3 can be configured by serial communication (115200 bauds 8N1).
•It needs to be disconnected from the modem (Figure 11, item 13) and connected to a PC equipped with a serial port (or via an
USB-Serial (RS-232) adapter).
•For the cabinets equipped with an optional SD card reader, the configuration is made through de USB-B connector (Figure 13,
item 12).
•Please note that the modem should be reconnected to the TMA-3B3 after its configuration.
10.2 ICOMSOFT TMA-3B3
You can download de software here: https://www.icomsdetections.com/docs/downloads.html
10.3 CONFIGURATION OF THE RADAR USING THE ICOMSOFT TMA-3B3
Firstly, power on the radar.
Secondly, launch the software by executing the tma3b3config_Vx.y.z.exe program (x, y and z refer to the version numbers). It will
open a DOS window and will take some time to launch the Graphical User Interface (GUI), please be patient while the software starts
up.
Screenshot 1: IcomSoft TMA-3B3 GUI when first opened
10.3.1 Step 1 – serial communication and time setting
Select the serial port your PC uses to communicate with the radar, the software will launch the communication once the port
selected.

12
If the clock of the radar is not set, the software will ask whether to set the time of the device. This setting is only necessary for
radars with memory card (SD card).
10.3.2 Step 2 – range and maximum speed configuration
Please note that the displayed ranges are given perpendicular to the bike lane direction. This means that the installation
angle of 45° is already taken into account in the calculations and the settings.
1. First set the min and max range values for the detection. The values should be close to the ones that would be measured
by tape measure.
2. If the default maximum speed is not large enough, change the maximum detection speed to 55 km/h. The trade-off for a
larger maximum speed is a shorter detection distance (D) of maximum 3.3 meters instead of 4 meters.
Screenshot 2: detection range configuration
10.3.3 Step 3 – Relay mode
10.3.3.1 Description
When switching on the relay feature, the internal relay is activated every time a bicycle is detected.
•The relay can be either linked to counting events or to “ITC” events (fast counting in the incoming direction, see section
10.3.3.3).
•When the relay is linked to counting events:
oOne click of the relay per bicycle counted (one click = temporary closure of the “NO” output).

13
oThis click occurs when the target is validated by the TMA-3B3. This validation takes place when the target leaves
the radar detection zone (which extends approximately from the installation point up to ~ 8 m from it). Compared
to the cut-off point of the laser beam, approaching targets will therefore be taken into account more quickly than
receding targets. If the radar detection is not validated, the validation of the target seen by the laser is done after a
timeout of 9 seconds.
•When the relay is linked to “ITC” events:
oOne click of the relay per approaching bicycle detected by the TMA-3B3 (one click = temporary closure of the “NO”
output).
oThis click occurs when the target is validated by the TMA-3B3.
•A minimum duration of 100 ms (configurable) during which the state of the relay does not change, is guaranteed for both
"active" and "inactive" times.
•If more targets are detected than the relay can output given the time constraint described above, they are added to a queue
until they can be issued to the relay.
•The size of this queue is fixed at 10 (configurable, parameter 041). If the queue size grows beyond the maximum size,
corresponding targets will be ignored (to allow limitation of the detection rate and as protection against possible abnormal
situations).
•The relay will not be energized in the inactive state (for consumption reasons) but can be configured in positive security if
desired.
•The relay will make a click at start-up (to be able to easily check its operation). All other clicks will take place for counting only.
10.3.3.2 Counting
Set the “Relay mode” to “Counting” to trigger the relay every time a bicycle is detected
10.3.3.3 .ITC (Intelligent Traffic Control) messages
The ITC feature will not only trigger the relay every time a bicycle is detected, it will also send an additional ITC message will be sent on
the RS-232 communication channel.
10.3.3.3.1 ITC messages description
ITC messages
•Are meant for traffic management applications in need of messages sent quickly or after a fixed delay after the target has
crossed the laser beam.
•Can be separated from the counting messages by looking to the “detection type” field of the message (see “11.3 Detection
types”).
•Are available only for incoming targets (targets that are approaching the detector when they are measured).
•Should not be considered for the counting application of the TMA-3B3 as they will be followed by a standard counting message
corresponding to the same target (immediately, or a few seconds after the fast message).
•Are deactivated by default.
10.3.3.3.2 Activation of the ITC messages
To activate the ITC messages, set the “Relay mode” to “ITC”.
10.3.4 Step 4 – save the settings
Once the limits are set, send them to the radar by clicking the button.
10.3.5 Step 5: Verify the detections in real-time
The configuration is correct when detected bicycles are shown as orange triangles.
i. Cars and other moving objects beyond the bicycle path should not be detected.
ii. The upper part of the graph shows the distance between the bicycle and the sensor
iii. The lower graph shows the measured speed (positive speed = approaching bicycles, negative
speed = receding bicycles).

14
Screenshot 3: object detections displayed on the Graphical User Interface (GUI)
10.3.6 Step 6 – close the software
When everything is OK, close properly the software. This will configure the TMA-3B3 for operation.
10.4 DATA
10.4.1 Real-time data on HyperTerminal
It is possible to verify in real time the measurements made by the TMA-3B3. To do so, please follow these steps:
1. Configure first the TMA-3B3 using the software
2. Open a serial port terminal software (like Hyperterminal, Putty, TeraTerm).
3. Type “p 50 8” to see in real time the measurements being sent. The format is
#CNT, SPEED km/h, RANGE m, TIMESTAMP, FUSTYPE where FUSTYPE consists in debug info from the data fusion routine
4. If this format needs to stay permanent even after a reboot, type “save”
5. Before reconnecting the TMA-3B3 to the modem, type “p 50 121” and then “save” on the command line interface to revert to
the machine-to-machine communication protocol.
10.4.2 Data collection using the modem
The modem collects the data from the radar, stores it and forwards it to the server of your choice in csv format. Please refer to
the modem manual for more information.
10.4.3 Data collection using the SD card
before unplugging the SD card, push the button circled in red in Figure 16 for 4 seconds to stop the data recording and then
remove the SD card. It is not necessary to unplug the battery, unplugging the battery will necessitate a time synchronization
using the PC and the configuration software.
Read the data from the SD card and insert the SD card again in the slot. The data recording will start again automatically, do not
push the button. Pushing the button will stop the data recording.

11.2 ASCII MESSAGES (PARAM 50 100) –SD CARD
When the message protocol 100 is selected, measurements are done according to a semi-colon separated CSV format:
TYP; DATETIME; SPEED; LENGTH
Where:
TYP is the detection type as a 3 digits number (see “11.3 Detection types”)
DATETIME is the timestamp of the measurement under the format:
YYYY/mm/dd HH:MM:SS,hhh
SPEED is the measured speed of the target in km/h (as a fixed length signed number). Decimals are separated by a comma.
LENGTH is the supposed length of the target in m (as a fixed length signed number.)
Note: the TMA-3B3 does not measure bicycles length.
Example:
001; 2020/12/31 23:59:59,999; +012,3; +001,8
Note: this is the format used to store the data on the optional SD card.
11.3 DETECTION TYPES
•1: Detection by association of one radar and one laser measurement.
•2: Detection by the laser only.
•3: Detection by the radar only.
•30: “ITC” detection for incoming targets for traffic management applications. This type of messages should not be considered
for counting purposes, as they will be followed by “type 1” messages (immediately or after a few seconds).
12 MODEM CONFIGURATION
Please refer to the separate 3G or 4G modem manual for the list of the most important parameters.
•The modem has settings stored locally. Those settings can be modified by changing the « setup.ini » file accessible via the USB
connection to the modem.
•Logs file are stored as well on the modem and can be accessed in the same way as the setup.ini file.

17
•Please note that the PIN of the SIM card is supposed to be 0000 when the modem is first initialized. If it isn’t the desired PIN,
the only way to change it is via the « setup.ini » file.
•The red LED on the modem should flash approximately every 4 seconds if the network is OK. A fast blinking indicates "limited
network services" (including limitations due to a wrong PIN).
