Interval Data – Allows you to specify the length of your intervals as well as how those

intervals are stored. The interval refers to the time (in seconds) that traffic data is ag-

gregated (minimum interval is five seconds). Interval data is stored directly into the

sensor’s SRAM memory, which is volatile and will not persist after a power cycle. The

number of intervals is limited to 246. You can also tell the sensor to move the data

from SRAM to the sensor’s flash memory by clicking the Store in Flash Memory

check box. This protects the data because flash memory persists after power cycles. The

capacity in flash is about ten times greater than SRAM. If the Store in Flash Memory

box is not checked, the interval data will remain in SRAM until it is overwritten. Flash

storage management features are explained in greater depth in the Data Collection

Setup section of chapter 7.

Vehicle Classification – Lets you customize vehicle classifications by length. Enter the

maximum length amounts for small and medium class vehicles in the active text boxes

and SmartSensor Manager will automatically determine the minimum lengths.

Lane Setup – Allows you to change specific lane information such as lane name and

direction of travel, for your own information and for identification.
You can also change scale occupancy (loop size) and scale speed (loop spacing). The

entry in these columns for each lane represents the manual scaling applied to the oc-

cupancy/duration and speed data. The occupancy scale factor is the ratio of each lane’s

loop size to the default loop size. The speed scale factor is the ratio of each lane’s loop

spacing to that of the default loop spacing. You can modify the scale factors by clicking

on the arrows to the right of each box.
