Colorado Department of Transportation
The Colorado Department of Transportation (CDOT) hired Clanton & Associates to improve the visibility conditions of the chain stations along the I-70 corridor. Vail chain station was the first to deploy lighting that focused on safety first for the truck drivers installing chains. During the design phase, Clanton & Associates modeled different lighting approaches to see if the sides of the trucks would be lighted even if snow banks forced the truckers to park closer to the traveled way.
The final design selected asymmetric luminaires with light distribution optimized for lighting the vertical surfaces of the sides of the trucks and the wheel areas. In addition, the lighting is designed to minimize light trespass onto neighboring properties by using controlled LED optics. Luminaires are also I/P addressable “ready” for advanced control systems. This design resulted in developing a new standard for CDOT chain up area lighting.
Clanton & Associates has developed street and pedestrian lighting master plans, lighting criteria, tours, pilot demonstrations, surveys, lighting measurements, and lighting research projects. Our extensive experience in creating street lighting master plans and guidelines for cities, assists our clients in making informed decisions regarding street lighting design to plan for the future of smart cities.
