Putting Our Experience to Work for You
At WSP, we contribute our expertise to the development of national and international standards for lighting design and engineering through our membership and active participation on instrumental committees and panels, including: the Illuminating Engineering Society of North America (IESNA), the Institution of Lighting Professionals (ILP), the Federal Highway Administration (FHWA), the American Association of State Highway and Transportation Officials (AASHTO), and the International Lighting Commission (Commission Internationale de l'Eclairage). These partnerships have resulted in the establishment of industry guidelines and, ultimately, a better lit world.
Our lighting design team is comprised of a diverse group of individuals including designers, architects, engineers, ecologists, daylighting experts, technicians and academics who design lighting projects around the world. With an extensive background in roadway, bridge, tunnel and mass transit lighting design, fixture design and manufacturing, lighting computation and construction support, WSP is experienced in defining appropriate lighting systems including the applicable control and electrical network requirements incorporating main and emergency power supplies.
Lighting for Tunnels
The design of tunnel lighting is a complex and specialized engineering discipline. Tunnels present the highest road user demands upon lighting and safety, especially during daytime hours when hazard levels are at their peak. Our knowledge regarding state-of- the-art technology and control systems for tunnels also provides us with the opportunity to design energy-efficient lighting solutions with low operation and maintenance costs.
For tunnel lighting, our designers ensure that portal and tunnel entrances and exits and interior zones have the appropriate lighting levels based upon the exterior ambient lighting to ascertain the correct eye adaption and ready identification of objects and other users within the tunnel.
