Chapter 3 — Using the EZ Belt
Step 1 – Select an Installation Location
The first step in the installation process is to select the location where the
EZ Belt will be installed. The EZ Belt should be placed exactly perpen-
dicular to the flow of traffic and should be installed on a straight stretch of
road so that vehicles are not hitting the belt on an angle.
For the best results, do not install the EZ Belt in a location where traffic
will be queueing up and stopping on the belt, or in a location where vehicle
will be making a turn over the belt or otherwise striking it on an angle.
Step 2 - Select Layout
Once you have selected your location, the next step is to decide what lay-
out to use. The EZ Belt is compatible with 5 standard layouts - L3, L5, L6,
L9 and L10. Which layout you select largely depends on the type of data
you want to collect.
The L3 and L9 layouts allow you to record data for volume information,
while the L5, L6 and L10 layouts allow you to record data for speed, class
and gap in addition to volume.
The most commonly used layouts are L5 and L6. The L5 layout is de-
signed for single direction traffic. The L6 layout is designed for bidirec-
tional traffic over two lanes. Chapter 5,
EZ Belt & Road Tube Layouts ,
contains more detailed information on each individual layout.
Step 3 - Prepare the Installation Equipment
Once you have decided on your layout, you’re just about ready to install
the EZ Belt. However, first be sure you have all the equipment you’ll need
to do the installation quickly and efficiently. The equipment you’ll need in-
cludes the EZ Belt itself, 25 foot mini road tube sections (two per belt) for
connecting the EZ belt back to the TRAX, mastic tape (including several
pre-cut 10 inch strips and a utility knife for cutting mastic in the field.
IMPORTANT
- It is critical that the mini tubes used to connect the EZ
Belt back to the TRAX Plus be IDENTICAL in length. The margin for
error when using a four inch tube spacing is very small, so having the
tubes be mismatched by even a small amount can have a negative effect
on your results. We recommend using matched 25 foot lengths when con-
nect either a one lane or two lane EZ belt back to the TRAX.
