TADI is the go to firm for TIAs. Since 2002, we have conducted over 500 TIAs for DOT, county and municipal approval – the most of any engineering firm in Wisconsin. Why is TADI the top choice? We let our client feedback and our 95% repeat client base say it best.

Client Testimonials

“We have worked with TADI on primarily “big box” Wisconsin-based projects for the past 12 years. We have found TADI to be well connected and current with industry standards. The TADI Team consistently offers creative approaches to presenting the facts and facilitating options to gain approvals. They are professional in their presentation and fair in their analysis of the issues. We highly recommend TADI for providing traffic analysis and potential solutions to complex problems for development projects of any size.” David Behrens, Principal at Greenberg Farrow

“TADI has performed numerous traffic studies and engineering reports on a wide variety of our projects. The high integrity with which TADI conducts themselves and their business shines through in the quality of their work and the positive interaction they have with those around them. TADI uses their extensive knowledge of the industry and ability to quickly assess situations to provide thoughtful insight on the front end of projects and then delivers effective and appropriate design solutions and reports in an easily understandable message to help gain project acceptance and approval. I highly recommend TADI to provide and/or help solve traffic issues for new and existing projects.” Greg Kost, Told Development


Our TIA client base includes clients from national retailers to local developers to municipalities. TADI has conducted TIAs in all WisDOT regions, Michigan, Illinois and Indiana. Our Senior Engineers regularly attend Plan Commission, Common Council, Public Hearings, WisDOT and County meetings to present the findings and recommendations of a TIA in simplistic and understandable terms. Our relationships with our clients and the agencies that review studies allows us to develop and deliver a complete project scope while our technical expertise means we meet agency standards the first time.
