SWTE’s values as a company focus on the communities we live and work in. As an Arizona Firm with families that work, live and play in our State, SWTE recognizes that we serve not only the citizens of the communities we work in, but also its visitors. Infrastructure plays a very visible role in the daily lives of our citizens and can make lasting impressions on visitors. In order to do this at the best level, SWTE specializes in Traffic Engineering analysis and design, and prides itself on the knowledge that our staff is specifically trained in, and receives ongoing training in Traffic Engineering skills.

Keeping you up to date.
As a firm that has completed both private and public projects throughout Arizona, we are familiar with not only many of the guidelines and standards for agencies in Arizona, but also have established relationships with their staff. SWTE is able to offer multiple traffic engineering-teams who are able to work on separate traffic engineering tasks within one project (e.g. ITS design team, traffic control design team). By having the capability of providing multiple internal teams working on the Traffic Portions of a project, SWTE is able to provide quality analysis and design for projects without over burdening a typical Traffic Engineering team staff of two to four people.
