413x · 17 Jul 2012 at 14:04

the ones that are on almost every other bridge. meaning to ask this for a while. are they measuring trafic flow? if they are even cams

i think they are used to monitor traffic. you sometimes see the footage shown on the news when they do a traffic update

Just for surveillance and are monitored, there for traffic reports and such, also useful for accidents etc.

They are often also linked into the police ANPR system to check vehicles for tax/mot/insurance etc.

Are you referring to the "War of the worlds" heat ray style that illuminate faint red ?

I suspect they are/have been installed in preparation for Pay by mile

We never went away !!

Googling for the ones I'm on about produces zero results but I have poor Google Fu anyway. I do NOT mean these cams

Yeah those. They exactly the same as the ones on poles linked a few posts earlier?

Thought they would be for traffic

Skeeter · 17 Jul 2012 at 19:22

CCTV for traffic.

Isn't there a website where you can get feeds from them?

They really aren't

Raymond Lin · 17 Jul 2012 at 19:49

OP probably went under one over the speed limit and now worrying if he will get a ticket

Not the blue ones maybe. But certainly there are some cameras in Chelmsford that I know are attached to the ANPR system

Ok so... As none of you seem to know what I'm referring to I pulled the wagon over

Took a pic

Scrambled down the grass bank and took another pic

Then hung over the edge and took a close up

Happy ?

Any breakers, Any takers ?

All I know is that back in 2003 when I was a naughty boy and caught by an unmarked police car doing 97.4 mph average speed over 0.5 miles - I was told that they had used two blue cameras on the side of the A34 to calculate my exact speed between them. They had been remotely activated by the police officer.

Apparently this was true as they relied on that evidence in Court and I got 6 points as a consequence of it.

EDIT - Those cameras look very similar to the pics you have posted.

Django x2 · 18 Jul 2012 at 17:28

Those bridge cameras are purely traffic flow. Either that, or I've been extremely fortunate over the last 150k miles and 6 years or motorway driving

when I did work for trafficmaster they went over the system and how it works with me (this was a few years back)

the cameras DO NOT record the first and last letters of the number plates, this was done on purpose so there was no question of the ompanies system being used for tracking cars..

We had some long term (2.5 years) road works on the main A-road of the city. They had these blue cameras on some of the bridges which fed digital displays saying "you are xx minutes from point B"
