Chapter 1: Choosing a Mounting Location
Note. Mounting height
is measured from the
road's height, not the
bottom of the pole. If
installing a new pole,
remember that part
of the pole will likely
be below ground.
Definition. Offset is
the distance between
the pole the sensor
is mounted on and
the edge of the first
lane to be detected.
