Adjusting the data interval
1
Determine what interval you need for your particular application.
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 suf-
ficient for your needs and would mean you don't have to download
the data as often.
2 Type the desired interval time into the Interval text field, or use the
up and down arrows to change it.
Creating, adjusting and deleting speed bins
1 To create a speed bin, press the + button at the bottom of the Speed
area. Each line is one bin.
2 To adjust the parameters of a bin, click on it and use the + 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.
3 To delete a bin, highlight it and click the – button at the top of the
Speed area.

Chapter 9: Setting Up and Downloading Sensor Data
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.
