 Update Properties – Refreshes lter properties updating changed values.

e individual lters and their properties are outlined below:

 Consecutive Zero Volumes – Checks the volume counts for each data record. Flags

data if the number of consecutive zero volume records is equal to or greater than the

set value; the default value is eight.

 Volume Reality Check – Checks each full day of data within the workbook to see

whether any data between 1 a.m. and 2 a.m. has a higher volume than the data from 1

p.m. to 2 p.m. indicating either awed data or an abnormal event.

 Missing Intervals – Flags all missing data records.

 Out of Bounds – Checks the given data value (Volume, Speed or Occupancy) against a

comparable value set in the Value eld. e Operator eld can be set to adjust the type

of comparison performed: greater than, less than, equal or not equal. Data is agged if

the given data value for a data record meets the comparison criteria for the lter. e

Auto Adjust Value can be used either to provide a suggested change to the data (when

the lter is run in Flag Items mode) or to automatically edit the data to the given value

(in Auto-Fix mode).

 Over Speed – Checks the speed value for each data record, agging it if the speed is

above the given Speed value. e Auto Adjust Speed eld can be used either to pro-

vide a suggested change to the speed (when the lter is run in Flag Items mode) or to

automatically edit the speed to the given value (in Auto-Fix mode).

 Repeated Values – Checks the given data value (Speed, Volume or Occupancy) for

each data record for multiple sequential entries that are the same value, indicating

potentially invalid or awed data. Congure the number of sequential entries in the

Repeated Intervals eld. e Auto Adjust Value can be used either to provide a sug-

gested change to the data (when the lter is run in Flag Items mode) or automatically

edit all sequential data records to the given value (in Auto-Fix mode).

To run one or more lters aer all properties have been set, click the Run Selected Filters

system will run the lters and update the data in the workbook when completed. In cases
