Below is the uncorrected machine-read text of this chapter, intended to provide our own search engines and external engines with highly rich, chapter-representative searchable text of each book. Because it is UNCORRECTED material, please consider the following text as a useful but insufficient proxy for the authoritative book pages.

A-1 APPENDIX A: SURVEY RESULTS (September 2017) 1 Does your Transportation Agency/Department have a Design Manual or policy design standards specifically for LED Roadway Lighting? 2 Does your Transportation Agency/Department have construction Technical Specifications specifically for LED Roadway Lighting?

A-2 3 Which industry recognized Roadway Lighting guidelines does your Agency/Department primarily follow? 4 As part of your LED Roadway Lighting Design Manual or Technical Specifications for either new design or retrofits, does your agency allow for reduced illumination (adaptive lighting) design criteria?

A-3 5 Are all new installations using LED luminaires? 6 Does your Agency/Department use other design modifications when applying LED lighting designs? I.E. occupancy sensors, curfew dimming, tune-able white, etc.

A-4 7 Please indicate what Correlated Color Temperature (CCT) your Agency/Department currently specifies for LED Roadway lighting. Check all that apply and/or write-in the other box. 8 Does your Transportation Agency/Department currently have any LED Roadway Lighting projects in design, in construction, or installed and fully operational? Check all that apply.

A-5 9 Approximately how much of your roadway lighting system is currently LED? 10 Does your Agency/Department require lighting calculations to be submitted as part of design reviews? 0 10 20 30 40 50 60 70 80 90 100 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26

A-6 11 Does your Agency/Department verify lighting levels as part of construction completion before acceptance? 12 If a spot replacement of a luminaire is required (due to knockdown, failure, etc.), is the fixture typically replaced in-kind (same source, HPS for HPS) or replaced with a new LED fixture (mixed source, HPS for LED)?

A-7 13 If there was a National Design Manual and Technical Specification available specifically tailored to LED Roadway Lighting would your Agency/Department consider using it?

Providing light beyond the limits of the roadway travel lanes benefits drivers’ visual performance, spectral content of light-emitting diode (LED) sources should be a design consideration, and there are not currently any health impacts from properly designed roadway lighting are among the findings of this survey report.

The TRB National Cooperative Highway Research Program's pre-publication draft of NCHRP Research Report 940: Solid-State Roadway Lighting Design Guide: Volume 2: Research Overview determines the current guidance for the use of Solid State Lighting (SSL); identifies the research that still needs to be accomplished to assist in its proper implementation; and develops a comprehensive, easy to use, set of guidelines using currently available information and new research being proposed as part of this project.

Also see this guide's accompanying pre-publication draft, NCHRP Research Report 940: Solid-State Roadway Lighting Design Guide: Volume 1: Guidance.
