28 CHAPTER 3 • SENSORS PAGE
Speed, Volume, and Occupancy (S, V, O)
The Speed, Volume and Occupancy (S, V, O) columns represent a quick data snapshot of
the most recent data packet received by a sensor. The fields represent average speed (S),
total volume (V) and average occupancy (O) over ALL lanes in only the most recent data
packet received.
Note
If data collection is turned off for a sensor, or if Collector was unable to retrieve data
during the last three intervals for that sensor—or for the defined expiration period,
which is set via the System page)—the Speed, Volume and Occupancy fields will
display only dashes.
Errors
The Errors column contains the percentage of the last 100 attempts to communicate with
the device during which an error occurred. The Errors column is useful for identifying sen-
sors that are communicating inconsistently.
Paging through the Sensor List
The sensor list has a configurable page size, which determines how many sensors are in-
cluded on one page. The page size is specified using the Display Settings control (see the
Display Settings Control section in this chapter).
If the amount of sensors that meet the filter criteria exceeds the page size setting, a paging
control will be visible at the bottom of the page (see Figure 3.5).
Figure 3.5 – Paging Control
When you have a sensor list that is longer than one page, use Previous, Next and the page
numbers to navigate to your desired page.
Note
Do not use the Web browser back and forward arrows for paging through the sensor
list.
