Figure I-4: Corner Radar
 Mounting pole – The sensor is usually mounted on a corner vertical mast
pole or strain pole. On wide approaches the sensor can also be mounted on
the back side of a mast arm using an appropriate sensor mount. In either
case, the sensor should be mounted with at least a six-foot offset from the
first detected lane. Figure I.5 illustrates common mounting locations: A –
far side of approach, B- near side of approach, C – back side of mast arm.
Other mounting locations may be possible if these are not available at your
intersection. Contact Wavetronix Technical Services for assistance if you
would like to test an alternative mounting location.
Figure I-5: Mounting locations
 Line-of-sight – Position the sensor so that it will have line-of-sight to the
entire detection area of interest. Avoid structural occlusion including trees,
signs, and other roadside structures.
 Detection coverage – Position the sensor so that it will be able to reach all
the specified stop bar detection zones. Also consider that the sensor will
track vehicles as they enter and exit desired detection zones. Accordingly,
the sensor will often work better if you position detection coverage to track
vehicles for several feet before they reach the first zone in each lane.
