Successful traffic engineering comes down to understanding the relationship between people and transportation systems. What factors influence motorists’ decisions on travel modes and routes? How will new developments influence people’s travel habits? How can the design of a street system improve safety, economic development, and/or quality of life? How can signal systems be coordinated to reduce delays, pollutant emissions, and motorist frustration?

New tools paired with unparalleled experience allow us to better predict behaviors and evaluate their impacts to develop more realistic, reliable solutions. Whether your goal is developing a new transportation corridor or maximizing the safety and efficiency of an existing facility, we can help you steer your project in the right direction.
