Automatic Traffic Recorders
In 1997 we introduced our TRAX line of automatic traffic data recorders. With their ease of use, yet powerful
capabilities, these recorders quickly became the top choice for people seeking to accurately count and classify traffic.

In the years since, we have made constant refinements and improvements, all with the goal of continuing to provide
the most technically innovative and electronically advanced line of recorders, while maintaining simplicity of operation.
We've also introduced new recorders, like the Radar Recorder and Stealth Stud to provide additional options for data

JAMAR traffic data recorders are now used across the United States, and Worldwide, by thousands of people who
appreciate their reliability, ease of use, and accuracy. They are employed on a daily basis by a broad range of users,
including Federal Agencies, State DOTs, Local Agencies, Planning Commissions, Universities, Police Departments,
Engineering Firms and more.

You will not find a better solution to your traffic data collection needs than a JAMAR traffic data recorder.

There are three different models to choose from, largely depending on how you want to collect your data. For more

Radar Recorder - The Radar Recorder is a unique member of the JAMAR line of traffic data recorders,
offering the ability to collect data through radar sensing rather than road tubes or loops. Ideal for locations where
speed or volume data is needed, it keeps personnel out of the road and can be installed in a matter of minutes.

TRAX series. It records data faster than any TRAX before it, providing the highest degree of accuracy. It also adds the
ability to download data to a USB Flash Drive and eliminates the need for battery charging or changing through the
use of long life lithium batteries.
