A triangle represents a complete detection.
◦
An orange triangle (lidar + radar) represents a complete object. Those triangle objects will be recorded with the
attributes timestamp, speed, length, and range.
◦
A grey triangle (lidar) represents a lidar object that could not be associated with a speed. Those objects will be
recorded with the last speed detected.
◦
A grey-blue triangle (radar) represents a radar object that could not be associated with a lidar object. Those
objects are not recorded.
Screenshot 3: object detections displayed on the Graphical User Interface (GUI)
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 and therefore only
generate red triangles.
ii.
If the bicycles are measured in both directions, check on the lower graph that both directions are
taken in account (positive speed = approaching bicycles, negative speed = receding bicycles).

–
close the software
When everything is OK, close properly the software. This will configure the TMA-3B3 for operation with the associated modem.

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
