roadway, or by clicking the Stop Bar up/down arrows.

Positioning the Sensor

Position the sensor by clicking on the sensor or its label and dragging it anywhere on the

roadway, or by clicking the Sensor arrow buttons.

e top number, shown in the sensor position display (next to the blue triangle), represents

the sensor’s position to the right or le of the center of the lanes being monitored (Cartesian

x coordinate); the bottom number represents the sensor’s position in front of or behind the

stop bar (Cartesian y coordinate), together forming a Cartesian coordinate pair (x, y). e

sensor’s height is specied by setting the Height value and reects the sensor’s mounting

height above the roadway (Cartesian z coordinate).

e resulting (x, y, z) coordinates describe the sensor’s position relative to the roadway and

are used to translate the sensor’s native range measurements to range measurements that

are relative to the roadway’s frame of reference. e sensor position is also used in the Beam

Alignment tool (see Tools).

Note

The sensor’s range is updated whenever the stop bar is moved.

Resetting Zones After Sensor Relocation

When the sensor location is changed, existing zones may no longer be within the sensor’s

detection range and the message below will appear (see Figure 6.3):

Figure 6.3 – Sensor Location Changed

It is always recommended to rst position the sensor and then congure detection zones.

However, if the sensor location is modied aer zone conguration, you can do one of the

following:

1 Manually check all detection zones and modify zones as needed (recommended). All

zones will still be available and their location relative to the sensor will be preserved.

If le uncorrected, the zones may no longer perform the desired detection function.

2 Reload only the channel conguration from a backup le created from the existing

conguration (the out-of-range zones will be deleted and the desired detection func-

tions may be compromised).
