M25 Gantry cameras

[Andy_P]

Browsing through some previous posts here, the consensus seems to be that the M25 cameras only come into action when the variable speed limit is in force (although no-one seems ABSOLUTELY sure )

Is there a reason then, why they are all marked as 70mph cameras in the speed-zoned database?

Wouldn't they be better off put in the "tbc" category? (My icon has a "?" in a red circle for those).

Or a new camera type - for example 'variable speed gatso' etc.

On a lighter side - has anyone ever managed to speed on that stretch of the M25 - or am I just unlucky to have never managed to even get anywhere near the speed limit! The last few times I've been there - I haven't even got out of third gear.

I drove round there last week, while the limit was 70, and I definitely got bleeps, on my Snooper, from some of the cameras. I know that the cameras may have been switched off, but better to be safe than sorry!

I would suggest that the cameras don't go in the TBC category, but that we assign them a special limit e.g. @?? or @Var, but don't set a speed, so that you will get an alert at any speed.

I think either I was either very lucky or the Met are slow in sending them out, but I managed a smooth 100+ through there about a month or 2 ago with no restrictions in place.
Obviously no GPS or nuffink attached!

I know from experience that getting a blip on the radar detector just means that the emitter is working, not that there is necessarily a working camera attached :P .

Can anyone with local knowledge tell us if the cameras are used at 70mph when the variable limit is off

I can confirm that the M25 Variable Speed limit gantry cameras are only operational when a variable speed limit is in force.

However, which group to put them in presents a quandary, we don't want to create more and more categories and whilst I agree that listing them as 70 is incorrect you'd have to be pretty dim not to know the speed limit when a variable lower limit is in force as every gantry displays the speed limit! These are compulsory rather than advisory speeds when lit.

Hi Darren,

I agree with you , but I was thinking about it from 2 points of view:

1) my software only reminds me if I'm going faster than what it thinks is the limit. So if I'm doing 60 while the signs are flashing 40 then a) I won't get a warning & b) I deserve a ticket . But if I'm only doing a few miles over, I'll still get the ticket

2) given the sterling work that everybody at PGPSWorld does, I'd like to reduce the workload. If we leave the cameras without limits, people, thinking they are working for the common good, will keep recording them only for Richard to have to filter them out!

3) (I know I said 2 POV )
I think this is a feature of British motoring that is on the increase cf. M42, so the sooner we can come up with a plan the better
