Installing the EZ Belt

Proper installation of the EZ Belt is very important for collecting accurate data with your TRAX. The EZ Belt and the TRAX’s air switches comprise the sensing device for the unit. As with all receivers, the sensor has to be functioning properly to record reliable information. With this in mind, examine your installations carefully and be absolutely certain that your unit is recording data as programmed.


The EZ Belt should be replaced on a fairly consistent basis. Older belts will eventually develop splits in the tubes that can allow water to enter. When an air pulse is received, this water can be forced back into the unit’s air switch, potentially causing serious damage. Do not risk expensive repair bills by trying to squeezing a fewextra studies out of old tube. One rule of thumb is to replace the EZ Belt after 30 days of use.


The EZ Belt should be placed exactly perpendicular to the flow of traffic to prevent double counting. Apply mastic tape to each end of the belt to start, then additional mastic can be applied to the EZ Belt to further secure it.


Once the EZ Belt has been secured, two 25 ft. mini tubes should be connected from the end of the belt back to the TRAX recorder.

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 connect either a one lane or two lane EZ belt back to the TRAX.

Checking for Accuracy

Once the EZ Belt is installed and you are collecting data, observe the traffic as it is being recorded to be sure everything is working correctly. If possible, check the EZ Belt periodically during the study to ensure they it has not been damaged and data is being recorded as programmed.


Upon completion of your data collection, remove the EZ Belt, clamps, nails and anything else that may be of danger to the motorists. The mastic may be hard to remove in some instances, especially in hotter weather. In those cases, it may be left on the highway and eventually it will blend into the asphalt from the flow of traffic.
