About Us

Traffic Engineering is not a department of TADI – it is TADI. In other words, we do traffic engineering better because traffic engineering is our entire focus. We specialize in a complete range of Traffic and Safety Engineering Services for public and private clients and have the largest traffic engineering staff in Wisconsin. Our size and expertise allows TADI to meet the demands of the fast-paced world of private development and provide comprehensive traffic services for projects requiring state, county and municipal approvals.
