Page 4: Introduction
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. -

Page 7: Detection Precision In Function Of The Installation Height, Offset And Width Of Bicycle Path
• Recommended installation’ height according to offset, for a 2 m wide bicycle lane and 15° vertical angle: O(FFSET) 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. - Page 8 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.

11 RADAR SETTINGS 11.1 C OMMUNICATION • The TMA-3B3 can be configured by serial communication (115200 bauds 8N1). • It needs to be disconnected from the modem and connected to a PC equipped with a serial port (or via an USB-Serial (RS-232) adapter). -
Page 12: Step 1 - Serial Communication
11.2.2 Step 1 – serial communication Select the serial port your PC uses to communicate with the radar and click “Connect” 11.2.3 Step 2 – background configuration In the “Background config” tab, set the background limit: The limit (red line) should be set at least 25 cm below the average range background, see Screenshot 1. -
Page 13: Step 4 - Advanced Configuration Options
Screenshot 2: detection range configuration 11.2.5 Step 4 – advanced configuration options 11.2.5.1 Maximum bicycle speed setting The maximum bicycle speed is by default set to 40 km/h. From TMA-3B3 v2.2.3 onwards, it is possible to change the maximum 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. - Page 14 • Can be separated from the counting messages by looking to the “detection type” field of the message (see “12.5 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).

• 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. -

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. -
