Hi all,

Is "Specialized transportation signal, directional & marker lighting" subject to the interior lit exterior sign illuminance limits? The Uplight/Trespass exemption section of the Ref Guide lists this separately from interior lit exterior signage, which leads us to interpret it is not subject to these same requirements. In which case, is there a industry definition of such "transportation" related lighting?

We ask as we have an airport project that includes a fleet vehicle que line "call board" which is used to pace the flow of commercial shuttle/taxi traffic through the landside terminal pick-up locations . It is LED but does not meet 200/2000 nit limits due to visibility needs. However, because this feature relates to transportation functions we weren't sure whether this precludes credit achievement.

Thoughts?
