Illuminating signs on dual carriageways

[storeydesign]

Question for you all, I've been speaking with a street lighting engineer on a scheme I'm working on and he's questioning the need to illuminate diag 606 on a dual carriageway opposite private access/egress anyone any thoughts?

TSRGD, schedule 3, part 4, paragraph 4, which applies to diagram 606:

Subject to sub-paragraphs (2) to (5), where the sign is placed on a road subject to a speed limit greater than 20 mph, and is within 50 metres of any lamp which forms part of a system of street-lighting, the illumination requirements for the sign are—

(a)where that system of street-lighting is illuminated throughout the hours of darkness, the sign must be illuminated by internal or external lighting for so long as that system is illuminated and may also be reflectorised; or
(b)where that system of street-lighting is not illuminated throughout the hours of darkness—
(i)the sign must be illuminated by internal or external lighting for so long as that system is illuminated and must also be reflectorised; or
(ii)the sign must be illuminated throughout the hours of darkness by internal or external lighting and may also be reflectorised.

It sounds very much like someone needs to become considerably more familiar with TSRGD. Also the lighting engineer should know basic stuff like this for starters, it won't be the first time they've come across this issue, unless they are new to the game.

Disturbing that this question even needs to be asked.

Lighting engineers often don't want the extra kit; especially if it is powered via their columns on a loop.

Stand ground, unless you're building a 20 limit boulevard, you're going to need to light this one.

But then every lighting engineer I know wants to avoid having any street lighting other than on restricted roads (and then in sufferance), perhaps they have been so successful they have forgotten issues such as sign lighting. Apparently active studs are a perfect alternative, which as the chair of the road marking and studs standard committee has said, is cobblers.

Nice to know there are still those out there who know the score.
