A-Trans Engineering

A-Trans Engineering is a small, specialized firm in transportation consulting where the principal is deeply involved in the design and analysis of each project. This commitment to quality was chosen over other alternatives where large firms lose control of their projects and key engineers are only used to market the project, not to complete it. Our clients have chosen us because we continue to find solutions to their problems and help them to complete their projects. Many of these solutions have incorporated creative design or have analyzed the traffic in ways that far exceed what other traffic engineers would or could do. A-Trans Engineering specializes in smaller, city planning where all aspects of transportation including pedestrian, parking, access, bicycles as well as the vehicle element are considered. The modeling analysis employed by A-Trans Engineering allows a visual modeling component for public forums so that the general public can better understand the transportation issues.
