H05000 - Viewing data on a TDC-12, TDC-8, DB-400 or DB-100
The REVIEW menu lets you see the data that you have collected before you download it to your computer. In the
event that you are not using a computer to analyze the data, the REVIEW menu lets you see the data so that you
can write it down for analysis.
You can review the data for Standard Turning Movement, Classification, Gap and Signalized Stop Delay studies.
You cannot review the data for Saturation Flow Rate, Stop Sign Delay, Spot Speed, and Travel Time studies.
The data for these studies is in a very compressed, complicated format that makes it unreasonable to try to
review it on the display.
The format for the display is the same for the different types of studies you can review. The screen, as shown
below, has several parts:

The data for these studies is in a very compressed, complicated format that makes it unreasonable to try to

The format for the display is the same for the different types of studies you can review. The screen, as shown
below, has several parts:
COUNT lists the number of the count being displayed.
INT lists the number of the interval being displayed.
BIN lists the number of the bin, or key, being displayed.
TOT lists the total of the data for the bin, interval, and count displayed.
Also listed is the date and time for the count and interval being displayed.
When the highlight is on COUNT, INT or BIN you can go to the next or previous value by pressing the CHANGE
(#14 & #15) keys.
You can move the highlight from COUNT to INT to BIN to EXIT and back with the TAB key, just like with the
other menus.
The procedure to examine data for a count is very simple:
Move the highlight to COUNT. Press CHANGE (# 14 or 15) until the desired count number is displayed. The
date, time, and count type can be used to find a particular count if you are not sure of its count number.
If you want to look at all of the data, then move the highlight to BIN and press CHANGE repeatedly while reading
the data displayed next to TOT. The BIN number increments each time you press CHANGE. After the last data
point in the interval is displayed, the INT number increments by one and the BIN number automatically goes back
to 001. You can go through all of the data by continuously pressing CHANGE.
If you want to look at a specific interval of data, then move the highlight to INT and press CHANGE until the
required interval is displayed. Then follow the procedure outlined above to display the data.
The number of bins displayed is a function of the type of count, and the number of keys used in the count. The
table below shows the relationships between the type of count and the number of bins used to store data, and
therefore the number of bins necessary to display the data.
INT lists the number of the interval being displayed.
BIN lists the number of the bin, or key, being displayed.
TOT lists the total of the data for the bin, interval, and count displayed.

Turning Movement and Classification counts are easy to understand, since the data storage format mirrors the
data collection process; the data for a particular movement or class type is stored in a corresponding bin. Gap
studies are almost as simple. Each timed gap is broken into 1 of 15 bins. It is important to note that bin #1 (and
bin #17, if used) stores the count data. Stop Delay studies use only three bins, one for the number of cars input
as stopped at the end of each interval, and the other two for cars counted as stopping or going through,
respectively.
If you always use the PETRAPro analysis software to download and analyze the data, then you probably never
will need to use the REVIEW option, except possibly to see what types of counts are still left in the counter.
