TRAX I User's Manual
Count Menu
When you select COUNT from the
Main Menu, the screen shown
above is displayed. The options on
this sub-menu are:
Basic
The most complex of the studies, Basic (Raw) data collection involves
time stamping every axle hit. Use this only if you are interested in the
raw data of a traffic study. Selecting this type of count will take you
into the tube layout selection menu, described on the following page .
Volume Only
If you select Volume Only you
will be taken to the screen
shown here, where you can
choose a study using either the
divide-by-two technique or a
straight axle count. Select VOL-VEH for a divide-by two study, where
every two hits is counted as one. Select VOL-AXLE for an axle count,
where every hit is counted as one. After you select the type of study
you want, you will be taken to the tube layout selection menu, de-
scribed on the following page .
Per Veh
Short for Per Vehicle, this study is one step below Basic. It allows
extensive manipulation of the data but does not time stamp every axle
hit. Selecting this type of study will take you into the tube layout selec-
tion menu, described on the following page.
Binned
This study can provide Class,
Speed and Gap binned files.
You can choose to collect only
one type of data, or two or three
types at one time, in any combination. Unlike the other three studies,
selecting this option does not immediately take you to the tube layout
selection menu. Instead you are taken to the screen shown above.
