Dartford Bridge SPECS cameras

I agree with Skippy.

And we are getting all out of proportion here. The original was about FOUR cameras on Dartford bridge, yet we seem to be having enormous palpitations. Four out of how many which give no trouble at all (and indeed, if those four warn for the ACTUAL speed limit as indicated by JaTe, quite properly not giving trouble either)?

The addition of the odd camera at school sites with short term speed limits is red herring too. Again, not many, in my opinion and so what anyway? How long (distance) does a school speed limit last? Variable speed cameras category should, in my opinion, be reserved for those cameras which are accompanied by recognisable signage - I'm talking here about the M25 and M42 with gurt big gantries full of signs which display the limits at the same time as you get the variable speed warning, NOT somewhere where there may be a mobile in the middle of a school zone after you've already passed the temporary 20 zone sign.

Inforad is a specialist thingy and I do feel that their users should take up with Inforad that there are SOME cameras which the Inforad system gets wrong.

Unlike TomTom and Garmin, Inforad have seen the wisdom of using the PGPSW database, no doubt based on the respective accuracy reputations. The OEM systems which use directional and average zone capabilities just don't cut the mustard with accuracy.

I have TomTom devices which for their own data are purported to use both directional and average zone capability. But they're simply unreliable for my data.

Please let's not start suggesting sledgehammers for nuts. I'd guess about 99.9% of us have some "issue" or "challenge" with cameras but in my case, directional and average zone is trifling so long as the camera sites are recorded accurately. PGPSW suits my needs, none of the others do.

ok, to keep this all in context can someone answer the following:

1) are these cameras physically present
2) do they say 'not in use' on them
3) what is the normal speed limit for that road
4) what is the current (reduced?) speed limit for that road

That was (effectively) the status when I last drove over it on Friday. I haven't seen the "Cameras Not in Use" signs for a while but couldn't assert they're not there and the gantries are there for cameras but could not confirm if they were populated or dummy boxes or nowt).

Will be Wednesday before I next drive over it, will re check

(Sod's law says they will have read this thread and rushed out and reinstalled them Crying or Very sad

if there are no 'not in use' signs then my opinion is that they should be in the database. whether they are empty or not is a different matter, there is nothing for us to work on other than a 'not in use' sign.

Doh! Four pages of discussion about four camera warnings which somebody doesn't want but which warn about a 50mph speed limit on a road which is subject to a 50mph speed limit. Rolling Eyes

Oh yes Skippy it has an off switch and it gets used on that bridge. It stays off past the junction with the A2 as there's a false variable entry there and it stays off down through the A21 as there's a wrong 60mph entry there for a 70 limit. The off switch also gets used through the SW M25 Variable areas from the A3 to the M4.

Not sure anyone buys an SCD to keep it switched off though Crying or Very sad
