#3560 — Energy saving auto dimming street lights

Norway - At highway 155 in Nes i Hole, 220 radars have been installed
on light poles. They detect oncoming traffic and adjust the strength
of the light. By doing this, the 9 km/5.5 mi stretch saves a whopping
2100 kWh per week. The extra investment will break even after just 4.5
years.

In the UK they save even more money by simply not lighting the roads.

Her indoors has now rung the council 6 times about the failed street 
light outside our house. Because of its situation on a corner, the area 
is pitch black and the pavement (and the road) is potholed.

She has been told that they only repair lights every 3 months and 
hospitals have priority, whatever that means. When asked who would be 
responsible if an old person had a fall because of the lack of lighting, 
the council representative said she could not answer that.

The appointment of the current contractor featured in Private Eye at the 
time.

Worse than this is that small "refuge islands" have been installed in 
the centre many of the main roads. These have a central pole with a 
light on top and a lit-from-beneath bollard each side. On most of these 
all the lights have now failed and many of the bollards have 
disappeared, presumably having been hit by vehicles.

They hung Christmas lights on the  streetlights through the town, but 
only on the working ones. It's hard to understand why they couldn't have 
put a box of bulbs on the cherry picker before they set off.

I take it this is Highways she's rung, and that one of you has reported
the potholes on the council website?

Yes, she has a reference number from them.

Not hard at all its compartmentalisation often occurs due to different bits 
of the services being  tendered out to different companies.
 Wait till you see what happens next month when banking services can be run 
by anybody as long as you money stays in a bank its safe. I see BT running 
cash machines or doing transfers, and advice for ininvesting in Tescos or 
almost anything else, also of course if the banks lose their money making 
delayed transfers, they will want to charge us for keeping our money.

As for streetlights, it is very difficult to tell who to complain to. all 
lamps are supposed to be numbered and  some are done by Higways agency, 
while others are council. In london its split three ways, Highways agency, 
TFL and each council.
In theory they should all talk to each other but we all know how reliable 
that is.

The council will not save money due to street lights not working. They are 
not individually metered. The Council pay based on the number and type of 
lamps and the number of hours of datkness measured by a typical photocell.

Only the Electricity Supplier would get a small benefit.

The council should want to repair it as it is still being charged for the 
power it isn't using.

But prefers the cheaper route of having someone fix all the
dud ones every 3 months, because that’s much cheaper.

Even sillier than you usually manage, and that’s saying something.

That used to be true, but modern street lighting is much more clever. 
Individual lamps can now be run for different numbers of hours and at 
different levels of brightness, if desired. The council can be billed 
accordingly, not at a flat rate.

Different method here,

"As a way to curb street lights power consumption and unnecessary
light pollution, Geolux proposes to selectively and progressively turn
on the street lights when they are needed, that is, when a pedestrian
or when traffic are detected on the street."

And for interest, talking to a colleague who is much closer to the 
industry, I'm told that UK motorways already have the ability to 
automatically dim/turn off the lighting based on traffic presence using 
the existing lane sensors[1], but that it's rarely used.

Interesting article,

Why you should be worried about connected street lights

http://www.techradar.com/news/world-of-tech/why-you-should-be-worried-about-connected-street-lights-1327834

but I think this is relevant aspect,

"Retired astronomer Christian Luginbuhl at the Flagstaff Dark Skies
Coalition published a research paper in 2014 which showed that if you
switch from high-pressure sodium to white LED, the 'sky glow' will
increase tremendously - even if you match the total number of lumens
(the brightness thrown out) of light."
...
...
...
Technology to the rescue

It doesn't have to be this way and, as usual, technology does have an
answer. Even progressive Flagstaff needs to take advantage of LED's
undoubted economic benefits, but unlike most towns it's not rushing in
and buying the cheapest LED solution without first trying out night
sky and eye-friendly alternatives already on the market.

The town is currently testing both narrow-band amber (NBA) and
filtered white LED (FLED). NBA fixtures - recommended by the National
Optical Astronomy Observatory - emit mostly yellow light, while FLED
is a normal white LED fixture with a glass filter over the top that
suppresses the shortwave blue light.

Together those technologies largely solve the problem of sky glow,
while also achieving the same low electricity costs, but they're
newer, so don't have economies of scale."

I just wish people would aim their external floodlights downwards instead 
of horizontally causeing half the light to be wasted.

In US recently, in one city:  "Officials say about 34 miles of copper
has been stolen from highway lights citywide."
===

"Copper theft continuing to darken Tulsa highway lights, setting back
expensive repair work 
...
...
"There’s been a recent rash of thefts," Ball said Wednesday. "After we
got the lights back on, they came back and stole all the copper that
was left."

Hang on is this not going to be a little off-putting for people going the 
other way or pedestrians etc?
 I could understand lights that dim as the sun comes up or get brighter as 
it sets.

t'other way works better, bright when ambient is bright, dimmer when 
there is no ambient.

There has been a trend to switch off the lights on rural roads/motorways
outside busy periods.  In some cases, they have been permanently switched
off. Also, many have been changed to delay switch-on until much lower light
level than used to be the case.

In UK, many of the new LED streetlamps which are controlled by mesh
networks have their light level set remotely, and automatically adjusted
at different times of night. They can be adjusted for once-off events
too, when a council is prepared to pay extra to have them on brighter for
longer if there's a local event resulting lots of people around later.

I am not aware of occupancy sensing type controls in the UK, although
they are used in some parts of continental Europe, particularly on
pedestrian footpaths.

The LED lights at our railway station and a footpath outside seem to sense
the presence of a person; they get brighter when you approach.
