About Us

    In an age of uncertainty, everything associated with Traffic Research & Analysis, Inc. (TRA) speaks to a company founded and focused on the principals of superior quality and lasting stability. Established in Phoenix, Arizona in 1988, TRA is the oldest continuously operating traffic counting company in the State of Arizona, and one of the oldest data collection firms in the United States.

   The founders of TRA recognized the need for a skilled, highly-trained, professional traffic counting company that could respond to counting projects in a timely manner and/or supplement an agency’s existing inventory and personnel.  For more than a quarter century, TRA has been committed to providing the highest quality traffic data collection services to city, county, state, and federal government agencies, councils of governments and associations of governments, as well as engineering firms, in California, Arizona and throughout the Western United States. This commitment to quality has been the foundation of TRA’s approach to traffic data collection and has led to its stability, longevity, and reputation for professionalism throughout the traffic counting and traffic engineering industries

    TRA continues to build a reputation in the transportation engineering community for providing reliable data in the most efficient, timely, and cost effective way.  Numerous procedures have been implemented to ensure accuracy in the traffic data including, but not limited to, performing annual field-testing on all equipment, conducting field checks during installation and during the count period, and running a series of validity checks on all data once retrieved from the field. TRA tests, semi-annually, every piece of its existing equipment inventory for any sign of problems and/or inaccuracies, and continually tests other products, both long standing and new technologies, to ensure that data is collected with only the best and most accurate products available.

   TRA is a Woman-Owned Small Business and is currently certified as a Disadvantaged Business Enterprise (DBE) with the Departments of Transportation in Arizona, California, Colorado, Hawaii, Idaho, Montana, Nevada, New Mexico, North Dakota, Oregon, South Dakota, Texas, Utah and Wyoming.
