They'll surely save a lot of money when the blackouts start.BBC News - 07/09/10
The growing number of councils across the UK that are switching off street lights has prompted criticism from MPs and road safety groups.
Some councils have turned off some lights at selected times, switched others off completely and turned traffic lights off in a bid to save money.
Commons Transport Select Committee chairwoman Louise Ellman said she fears road safety was being compromised.
The UK's 7.5m street lights cost about £500m each year to power.

Some kind of PIR sensors installed on street lights in quiet areas might be a good idea.
If they could be linked so that they light in threes - so there's always one light ahead of you and one behind - even better, though this is probably beyond the imaginations of councils.
Traffic lights only really need a red. The amber and green are superfluous.
Shops and other unnecessary lighting should all either be timed to go off at the quietest times, put on timed dimmer switches or on PIRs.
All external house lights should be on PIRs.
And as for Christmas....

The lamps used at present cant be switched by motion detectors since they take a minute or more to warm up.
LEDs light instantly and could be switched by PIRs, and I suspect that such will soon be installed for trials.
I suspect that most of the public will hate the idea, women especially like to see the whole road lit, for as far as they can see, and would not like dark areas.
PiR detectors might not respond well to vehicles.

(cue response about 'dangerous' junctions and 'accident blackspots' blah blah blah)

streetlights
our village is quite small and we have a about 8 streetlights apread along the main road, too be honest they are not worth having, we walk the dogs at night and use a torch as do most people in the village.
It's the motorway and dual carriage way lights that really wind me up, you have them in the middle of the road and both sides, they are also really close together you could get rid of every other one and it would still be "daylight"!! don't even get me started on business parks and shopping centres that are lit up like christmas 24/7 Grrr!

For LED area and street lighting you will see smart systems which follow you around. These are already in development tracking movement across spaces and increasing light levels locally while using a lower maintenance level at greater distance from the people walking in the space. Also invisible LED systems for street lighting, changing from large high power lamps to more smaller fixtures which will have a lower impact during the day and give a more even light at night.
I don't know if either of these will ever make it into the real world, I'm not sure so many public bodys will have the money for the necessary investment.

How many people, women especially, actually walk around the streets between 01:00 and 6:00 in the morning, especially on country roads, motorways and dual carriageways?adam2 wrote:I suspect that most of the public will hate the idea, women especially like to see the whole road lit, for as far as they can see, and would not like dark areas.
