Definition. Interval
data is collected for
all the vehicles that
pass the sensor in a
set amount of time
(that time is called
"the interval"). A
shorter interval means
the sensor records
data more often, so
onboard storage fills
up faster. A longer
interval means you
can leave the sensor
alone longer.
Definition. A speed
bin is a classification
of a vehicle based
on its speed (usually
a range of speeds);
which speed bin a
detection falls into
is part of the data
collected about it.
For interval data, the
sensor records how
many detections
fell into each bin
over the course
of the interval.
Note. The first
speed bin created
defaults to 145; it is
the maximum speed
value and cannot
be changed. This
bin can't be deleted
until all the others
are deleted first.

Adjusting the data interval
Determine what interval you need for your particular applica-
1
tion. For example, for real-time applications, you might want to
aggregate data over short periods of time to reduce reporting
latency. On the other hand, for a long-term testing site, long
intervals could be sufficient for your needs and would mean
you don't have to download the data as often.
Type the desired interval time into the Interval text field, or use
2
the up and down arrows to change it.
Creating, adjusting and deleting speed bins
To create a speed bin, press the + button at the bottom of the
1
Speed area. Each line is one bin.
To adjust the parameters of a bin, click on it and use the +
2
and – buttons to change the value, or type a new value in. The
number that you see is the maximum speed for that bin. For
instance, in the image above, the highlighted bin is for vehicles
traveling between 66 and 85 miles per hour.
To delete a bin, highlight it and click the – button at the top of
3
the Speed area.
