Using system review, optimization, implementation and field refinement, GHA performs quick, cost-effective reviews of existing intersection operations in all traffic signal platforms and help reduce delays, emissions, and energy costs. Monetary investment in signal timing improvements can be recaptured many times over in terms of social, economic and environmental benefit.
