It means that they think there is a problem with speeding in that area & rather than send a patrol car to monitor the problem on a regular basis, they will put these signs up instead & send a patrol car now & again. It looks as though they are doing something about the problem, but means it does not cost them in man hours either. Am I being too cynical?
To be as brief as poss as it was explained to me when we went up to Scotland and they were there last year--
1st camera clocks your speed and reg on entry into the system 1/2 way same again and again its recorded on the last camera--then it calculates a mean average speed for each takes account of the distance and if its over the limit as a mean average speed you get the fine and points delivered by post a week or so later !!-dead sneaky and a great moneyspinner for Mr Brown and the other nice honest people we have voted in to run our country.(dont get me started on that one)----it seems stange to me but you can enter at say 20mph over the limit then slow down to 20mph under for a distance and still be ok?
--My thoughts were if you enter at 100mph would it work to drive at 10 for the rest of the recorded distance?
I wonder if any other members can explain it better ?(or worse have been caught!)
...that's average speed cameras. I've never heard of anybody being 'done' with them though.
Its quite funny to watch people that don't understand the word 'average'...they see the camera over the road and slam on their brakes.
I usually spot a car (doing 50) at the start and as long as you are the same distance from that car at the end, you will also average 50. The best plan is to tootle along at around 40 and make everbody overtake you, then pull out overtake them all again just before you leave the roadworks...hours of amusement!
An example of driving the wrong driving behaviour - Avg Speed cameras result in tailgating as cars attempt to hide behind lorries or get even closer to cars.
A speed course instructor told me that these Avg Speed cameras don't catch too many (i.e. they actually work), but as a result they don't get deployed as much as the ones that make money (that don't work in slowing you down beyond the camera!).
Average speed cameras IMO are the best type of cameras. You enter a point where by lots of accidents have occurred and you are limited to a set speed for the entire duration, not just where the cameras are. It means through a village, you are restricted to doing 30 or 40 ALL the way through it. It's a fantastic way of slowing down.
I appreciate the issue with tailgating and getting close to try and hide from cameras, and it is an issue.
However, i like to step back a bit and look at things from a technical and logical way of thinking. And i have a question. I'll point out at this moment in time that i realise we're off topic as the topic isn't on average speed cameras but it's gone that way so i'll carry it on.
We know that not all cameras (of all types) are active. Some are just shells, others are switched off, now back to SPECS.
We have confirmation that they can only record one lane, so effectively, a SPECS area with 2 cameras, if you enter in the left lane, and leave in the middle lane, then you can't get caught. What about a specs area with 3 cameras, on a dual carriageway. Does the average speed just go from 1 camera to the next, or does the average speed ALSO work out on the whole from the first to the last camera. If this IS the case, the entering on the left lane at 85mph, moving to the right for the 2nd camera, and moving back to the left for the 3rd and final camera would result in an average speed of ...85... Thus a prosecution.
If on the other hand, it DOES NOT record a total average and just separate averages from camera to camera. What happens if camera number 2 (the middle one where you move to the right hand lane) isn't on. And the TRUE average is between the 1st and 3rd Camera, both of which you'll pass in the inside lane..... thus.... prosecution.
