8 INTRODUCTION  SMARTSENSOR ADVANCE USER GUIDE

you position detection coverage to track vehicles for several feet before they reach the

rst zone. e closest detection zone provided by SmartSensor Advance and Smart-

Sensor Advance Extended Range is 50 . (15.2 m) from the location of the sensor. e

farthest detection zone provided by SmartSensor Advance Extended Range is 900 .

(274.3 m). e farthest detection zone provided by SmartSensor Advance is 600 .

(182.9 m). e sensor is usually used to detect incoming trac, but it can detect in-

coming or outgoing trac, and it lters out the opposite direction trac. With Smart-

Sensor Advance Extended Range, incoming large vehicles are typically discovered by

about 750 . (228.6 m) and small vehicles are typically discovered about 600  (182.9

m) from the sensor. With SmartSensor Advance, most incoming large vehicles are dis-

covered by about 500 . (152.4 m) and most small vehicles are discovered about 400 

(121.9) from the sensor.

Figure I.1 – Mounting Locations

 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. is will prevent departing

trac 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 lters 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 . (12.2 m) and minimum of 17 . (5.2 m) is

recommended. If the sensor is higher than 30 . (9.1 m), the oset should be less than

50 . (15.2 m) to increase accuracy.
