My radar detactors goes ballistic when approaching it.. and when passed it calms down.


The Box on the lamp post is nothing that i've seen before!

The 'rubber bands' i have but there are only two on the road.. with this 'box'


??


Phil
anyone else seen them?

scoobydevil1

not sure what they are m8
on the A41 they have the same thing 4 bands sunk into the road it transmits you speed to a police car which is a couple of hundred meters away so you can't see it .
not very good as it depends on your tire size only been stopped once on the A41 with this got let off as they were testing it out.
hope that makes sense

The two strips on the road are for speed monitoring. Round this neck of the woods they've been used to test spots that are being considered for speed cameras.

If the average speed of the traffic is high enough, sure enough, the camera pops up a few weeks later. FWIW you can wipe these wires out by locking up violently as you drive over them. Snaps 'em clean

As for why your radar detector is pinging, that's a strange one. Are you absolutely sure it's related to that box? Incidentally, is that box connected to the strips on the road? From the pictures you took it looks like they're linked to the box on the opposite side.

AFAIAA the "strip" devices simply record the speeds of passing vehicles, with the data being stored until the detector is collected and analysed. However, if you're registering a strong signal when passing them, it could be that they're transmitting the data somewhere else in real time.

I'm just guessing now, so with a bit of luck someone who knows will pipe up, but that would explain things...

I'm guessing that your detector hates For Sale signs. See if it goes off when you pass your local estate agents.....

SJ_Skyline

Tesco nearby?

what would scooby do

Use a large lump-hammer to test how secure the boxes are attached to the lampost - ISO 9002 test if anyone asks

them thar strips measure traffic frequency as the ability to accurately measure speed is boll-hox, wheel base dimensions make it ineffective, what it can do tho is measure volume of traffic, they do this where they are thinking about placing traffic lights, a crossing, a bypass etc etc

carl

Only if your wheelbase is smaller than the distance between the two wires.

It goes like this:
front wheels trip first wire, then second wire. Speed computed using distance/time.
rear wheels trip first wire, then second wire. Speed computed using distance/time.

Just remember that the number of cars going through is about half the number of speed readings you get (unless there are a lot of unicycles in your area).

Or bikers doing wheelies

beemerboy

that for sale sign is begging to be defaced with Austin Powers!!!

beemerboy

ride back and forwards over them with a uni-cycle, that would **** their data up for them...

pugoetru

they are usually for measuring traffic volume shouldnt make your detector go mad though.
the box is usually on ground maybe that one has a radio link or something thats whats triping your detector

WRBlue-STi7-Prodrive

They are for measuring how much traffic uses that stretch of road!!!!!

steve_nairn_sti

Pugeotru and Peanuts are spot on. They are used for trend analysis on the volume of traffic passing the area. They cannot be used for speed monitoring.

That info comes from a very reliable source.

jhdee

Sorry guys - they are speed traps too !!! Clicky
Have a look at Speedmaster DS2 !!!!!!!

jhdee

steve_nairn_sti

Jhdee,

Read your link.

It appears that the DS2 uses three sensors on the road rather than the two sensors shown in the pics. This may be where the confusion lies. Well pointed out though.

Wait until I get my hands on my contact!!

j_p_h

Ive seen these things knocking round here for a good few years. If they are speed traps ive never been done by them.

Dr Hu

What happens when a Twin rear axle lorry goes over them?

SteveLegacy

I thought to be accurate they needed to have 3 strips (and a camera, else where is the evidence that you've been speeding??), 2 are only used for traffic volume measurement.

If you relied on the first wheel over the first, then over the second strip, you could totally bugger them up by riding up and down on a unicycle, so it sees an odd nuumber of axles going over it!

jhdee

Steve NS

You''re absolutely correct. The photo in this post goes right across the road - its therefore probably measuring traffic volume. Be careful though - those that are buried in the tarmac sometimes only cover half the width of the road and therefore don't need the third strip. Locally this type is used near lay-bys (sp ??)where the grey box is in the lay-by.
I've actually seen the so-called "safety van" connected to one of these boxes and it only has two wires !!! The area also has the camera warning signs.

JPH

A copper usually needs to be attached to them i.e. they are normally manned type traps. Must admit they don't appear to be used very often - probably collecting far too much funds with the Gatso's


My only message is be careful - next time you're having a Montoya moment - was it 2 or 3 wires ??? was it half way across the road or not ??? may be too late

The strips are used for surveying traffic density only. The box is put up a hight to stop people tampering with it. Loads of lovely electrics and clever stuff inside setting off your bleeper.
Thats what I heard anyway!

PMSL @ what would scooby do

Fookin Funny

OK OK OK...
the Rubber bands have been on the road for the last few week.
There just as you come into a 30mph zone... at the end of the 30mhp zone.. about a 1 mile (if that) down the road is another two rubber bands and thats connected to a box thats chain up at the bottom of a lamp pos as they usually are.

No the box on the Lamp post shown in the pic.. is only about 6' hight! and has only been on the lamp post the last week or so.
This is why Its got me thinking.. as i drive the same road every time i take Amanda home.. then i come back that way to my house.

it is near a Texeco petrol straition..BUT my detector has never gone off before passing that!

My Radar is going ballistic when parrallel with the lamp post mounted box.. when driving away from it.. it calmes down.
the pic shows my Radar decector at 6.. it can go t 8/9.
the pic was taken on the opposite side of the road to the box!

On a closer inspection to the box.. it looks like it faces the on coming traffic and has a 'window' which is the same colour as the rest of the box.. is that a hidden camera!?

Salsa,

are the two sets of bands at either end of a straight bit of road? The picture of the box next to the for sale sign appears to have an 'open' area (possibly fibre-glass?), which could have a radar gun behind it?
Other possibility could be that it's a micro-wave transmitter, which could send data to the other boxes or a police vehicle, so they can nick you further down the road??

I'm just guessing, but does sound rather sinister!!

DaveD

iTrader: (2)

D'oh!

Just thought.....

could be a conventional traffic count (rubber strips in road), but with an added radar to get speed of traffic. Wouldn't 'catch' anyone speeding (no camera), but would be able to record traffic density, and some indication of speed!!

salsa-king

that could be it.

its on the Burton Joyce road in Nottm
