Meet the Traffic Team

Let us introduce ourselves – we are Sain Associates’ Traffic Team! Sain is widely recognized as one of the top traffic engineering firms in Alabama, with 15 Traffic Team members serving clients from our Birmingham headquarters and branch offices in Auburn, Mobile, and Huntsville, Alabama, and Pulaski, Tennessee. We have worked throughout the Southeast to improve traffic flow, reduce roadway crashes, and help plan for the growth of our cities.

Our team offers a broad range of transportation services through our collective knowledge base. We maintain on-call contracts with the Alabama Department of Transportation (ALDOT) and the Tennessee Department of Transportation (TDOT). Sain provides engineering and consulting services to various agencies, including the Birmingham Regional Planning Commission and numerous cities and counties across Alabama. Some of our traffic services include traffic impact analysis and simulation modeling, event traffic management, signal design and timing, ITS planning and design, feasibility studies, access management, at-grade railroad crossing diagnostics, and many others.

Our practice continues to make lasting impacts on our community thanks to the expertise of our leadership:

Some notable projects we have provided Traffic services include:

We enjoy working together as a team and are looking to add a Traffic Engineer to our team. On a typical day, you may help design a new traffic signal, retime an existing traffic signal system, conduct a traffic impact study, or develop a deployment plan for field devices on an ITS project. Join our traffic engineering team and make a tangible impact on improving the safety and efficiency of transportation systems in your community!
