Traffic Signal Systems
A modern and well-operating signal system is essential to effectively meet the growing demands of traffic and serve the community's needs. KAI has extensive experience working on signal design projects that involve innovative, solutions-oriented approaches. KAI has led the development and implementation of optimized signal timing plans and parameters at hundreds of intersections nationally. By providing conceptual and functional intersection design layouts in-house, KAI can successfully develop the initial intersection improvement footprint and confirm design parameters. KAI staff authored various industry-leading, national guidebooks, including the Traffic Signal Timing Manual, the Transit Signal Priority Research for the Federal Transit Administration, and the Transit Performance Measurement Guidebook.
