3 INTRODUCTION
The TMA-3B3 is the combination of a microwave radar and a light emitting sensor, designed for bicycles counting on bicycle
lane. The output consists of a serial interface. The unit can be delivered with a solar panel and with an additional cabinet
containing a battery, a modem and a solar regulator.

5 SAFETY PRECAUTIONS
Only skilled and instructed persons should carry out work with the radar product. Experience and safety procedures in the
following areas may be relevant:
•Working with mains power
•Working with modern electronic and electric equipment
•Working at height
•Working at the roadside or highways
Please follow these safety precautions:
-Make sure the electricity supply is within the range shown on the label and the manual of the product.
-All connections must be made whilst the power supply is switched off.
-Ensure the wiring is correct as shown in the manual before switching on the power supply.
-Never use a damaged radar.
-Opening the outer casing is deemed dangerous and will void all warranties.
-Ensure the radar is mounted correctly and the screws and bolts of both radar and bracket are firmly tightened. The
radar needs to point to the region of interest for proper detection.
-Ensure the radar is configured properly.
6 THEORY OF OPERATION
1. Unpack the unit and check the following items are in the box (please refer to Figure 1, p. 4):
A. Radar/lidar with rear side connectors and mounting bracket
B. Additional cabinet with solar regulator and modem
C. USB AB cable
D. Battery 100 Ah (optional)
E. Solar panel 85 W with mounting bracket (optional)
F. User’s guide
G. Power supply & communication cable
2. Place the unit on the field and align it to the traffic (see title 9, p. 6).
3. Install the additional cabinet (B) on the same pole.
4. Place the battery (D) in the cabinet and connect it.
5. Mount the solar panel (E) according to the instructions (see title 15, p. 18).
6. Connect the cable from the radar to the additional cabinet.
7. Connect the cable from the solar panel to the additional cabinet.
7 LED indicator
The LEDs blink at power up and are then shut off.

REMARKS
•Make sure the plug is fully inserted in the socket and the cap is firmly tightened on the socket.
•Please disconnect the radar from the power source before maintenance intervention.
9 INSTALLATION GUIDE
9.1 DIRECTIONDETECTION
The TMA-3B3 measures in both directions, and associates a + sign 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.
9.2 CHOICEOFTHEINSTALLATIONLOCATION
•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 ofthe 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.
9.3 PHYSICALINSTALLATION
•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

2 m
H(EIGHT)
1.4 m
1.75 m
2.10 m
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.

9.4 DETECTIONPRECISIONINFUNCTIONOFTHEINSTALLATIONHEIGHT,OFFSETANDWIDTHOFBICYCLEPATH
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 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.

Figure 6: detection precision in function of offset (O) and width of bicycle path (W) for an installation height (H) of 2 m
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
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.
