¾ RF Channel – In case there are multiple SmartSensors in close proximity, the user
should assign each sensor a different RF Channel. This will reduce the interference
of the sensors with one another
c. “Communication” tab – Leave all settings on default unless otherwise known
d. “Data Collection” tab settings:
¾ Interval Data – specifies in seconds the interval time over which traffic date are
aggregated. The minimum interval allowed is 5 seconds
¾ Vehicle Classification – Specifies the length ranges for vehicle classes
¾ Lane Setup – Specify lane name and direction. “Scale Occupancy” and “Scale
Speed” columns are used when tuning the sensor. These factors are the ratio of lane
occupancy/speed to the default occupancy/speed.
¾ Default Loop Size and Spacing – If contact closure cards are being used, the cards
will read the Default Loop and Size and Spacing. These values are also used when
calculating the occupancy and speed scale factors.
