8 INTRODUCTION • SMARTSENSOR ADVANCE USER GUIDE
you position detection coverage to track vehicles for several feet before they reach the
first zone. The closest detection zone provided by SmartSensor Advance and Smart-
Sensor Advance Extended Range is 50 ft. (15.2 m) from the location of the sensor. The
farthest detection zone provided by SmartSensor Advance Extended Range is 900 ft.
(274.3 m). The farthest detection zone provided by SmartSensor Advance is 600 ft.
(182.9 m). The sensor is usually used to detect incoming traffic, but it can detect in-
coming or outgoing traffic, and it filters out the opposite direction traffic. With Smart-
Sensor Advance Extended Range, incoming large vehicles are typically discovered by
about 750 ft. (228.6 m) and small vehicles are typically discovered about 600 ft (182.9
m) from the sensor. With SmartSensor Advance, most incoming large vehicles are dis-
covered by about 500 ft. (152.4 m) and most small vehicles are discovered about 400 ft
(121.9) from the sensor.

˽ Line-of-sight – Position the sensor so that it will have line-of-sight to the entire detec-
tion area of interest. Avoid structural occlusion including trees, signs and other road-
side structures.
˽ Closest roadside – If you install the sensor on the side of the road (instead of over-
head), select the location closest to the lanes of interest. This will prevent departing
traffic from occluding approaching detections.
˽ Through-Movement Detection – If only through-movement detection is desired, po-
sition the sensor to avoid detection of turn-only lanes. Consider using speed filters to
remove the impact of turning vehicles.
˽ Mounting Height – Mounting the sensor as high as possible is recommended to reduce
same lane occlusion. A maximum of 40 ft. (12.2 m) and minimum of 17 ft. (5.2 m) is
recommended. If the sensor is higher than 30 ft. (9.1 m), the offset should be less than
50 ft. (15.2 m) to increase accuracy.
