GPI’s traffic engineering solutions include planning, analyzing, designing, and the inspection of transportation projects ranging from simple site developments to complex traffic signal systems. We are one of the recognized leaders in ITS solutions, often involving complicated simulation modeling that is used not only to evaluate the projects merits, but also as visuals, including virtual reality, for the general public to understand the benefits. When it comes to traffic engineering services, we are committed to continue the trend started by our founders of providing new and innovative solutions.
