Using the Integrated SpeedView Traffic Data Computer
Basic Operations
The integrated traffic computer enables you to collect traffic data for oncoming traffic. Every time the sign
is turned on and the traffic computer is enabled, a new traffic study is begun. The traffic computer will
continue to read oncoming cars and count them and store their speeds for analysis.
Traffic Study Files
The data is stored internally and is downloaded to a USB thumbdrive when it is inserted into the sign. The
data is retrieved in a comma-separated variable (CSV) file format with a .csv extension. This file can easily
be read using a text editor.
The traffic study files are numbered sequentially with the first four characters of the filename representing
the serial number on the sign on which they were captured. For example, the file 12340005.csv would
represent the 5
th
traffic study that was collected for the sign with serial number ending in 1234.
Each study file contains a header section which captures the starting and stopping times of the study along
with the download time, the type of radar used, the filename and the speed bins which hold the actual traffic
data.
New summary data is then added to the file for every time interval (typically 5 minutes) that is being
monitored. Hourly totals are added as an additional line at the top of every new hour. If the traffic
computer study is not allowed to reach at least one full speed interval, no data will be added to the file and
the file will only contain the headers without any speed data.
Data will continue to be appended to the file until the unit is powered off. Once the unit is powered back
on, the last study is closed out and a new study will begin along with a new data file.
Traffic Study File Retrieval
To retrieve the data from a study, power off the sign and then turn it back on with the traffic computer
enabled. This will close out the study and update the file contents. The blue LED should be blinking which
indicates there is data ready to be downloaded. Insert a thumb drive into the USB port on the sign and the
text message will change to
bSy
(busy) to indicate the drive is being accessed and the data file is being
transferred over to the thumb drive.
NOTE: If you insert the thumb drive into the sign without cycling the power to the sign, only any
previously stored studies that have not been previously downloaded will transfer. The currently
running study will not transfer.
Once the files have been transferred, the blue LED will turn off and the
bSy
message will go away. The
USB thumb drive can then be removed from the sign and taken to a computer running the SpeedView
Traffic Analysis Software.
Detailed Steps
Starting a Study
1.
Turn the sign ON. This will begin a new study.
2.
When the sign boots up, it will do a self-test, display the sign’s software revision and serial number
information, flash all of the sign LEDs and then it is ready to begin counting traffic.
