Transportation Lighting Design


Clanton & Associates has successfully designed and engineered lighting designs to illuminate roadways, interstates, complex interchanges, train stations, bus stations, bridges, tunnels, parking areas, pedestrian tunnels, and pedestrian areas. With a design process that focuses on creating nighttime environments of the highest quality, we focus on minimizing unwanted glare, light pollution, and light trespass. We collaborate with our clients and design team to satisfy the unique goals of each project. Our team participates in the research and development of new lighting standards and applies the most current visibility criteria to each project. By aligning projects with future technology and ongoing research, Clanton & Associates provides beautifully integrated design solutions which save energy, are easy to maintain, and enhance visibility.
