The SAS-1 as a Count Station
The SAS-1 has the capability to archive traffic flow measurements for five lanes for up
to several weeks depending on the size of the installed non-volatile memory ( 1 Mbit,
2 Mbit, or 4 Mbit) and the selected update period (5, 10, 15, 30, or 60 minutes). The SAS-1
continually updates the archive data independent of it's default mode of operation.
The archive storage is circular so that when the archive grows to the maximum size,
the oldest measurement data is discarded to make room for the most recent.
SAS Monitor and Setup (Ver 6.01.01) provided by SmarTek Systems includes tools to
setup the SAS-1 archive parameters, retrieve the SAS-1 archived data, and to convert
the archive data file to PRN Volume files (Dmmddnnn.prn). To use the SAS-1 as a
Vehicle Count Station, the following steps should be followed:
1) Setup/Edit the SAS-1 Archive Header using SAS Monitor.
2) Send the Header Records to the SAS-1 (
this clears the SAS-1 archive ).
3) Set the SAS-1 Date and Time ( this clears the SAS-1 archive ).
4) Wait for the SAS-1 to collect the data (days or weeks).
5) Retrieve the archive data file from the SAS-1.
6) Convert the archive data files to PRN Files (
must have corresponding header files ).
Setup/Edit the SAS-1 Archive Header
1) From SAS Monitor's main display, open the SAS-1 Header Editor by clicking the
Archive/Edit SAS Archive Header menu item. The editor opens with all fields
filled in with default values. These values may be edited or an existing SAS Archive
Header File may be opened to use previously edited values.
