Speed camera update - A40

I've just submitted two updates, I hope they make sense.

On the A40 near Acton, the DB says there are two cameras. When I drove past there on Sunday, there seemed to be just one in the middle of the dual carriageway. So, I have amended one to be reversable and suggested the other can be deleted.

Is that the right thing to do?

cheers

Alan

Apparently not. See here.

This might be better moved to the speed camera forum section?

The reason why there are two cameras shown depends on your system.

Brands like the TomTom cannot use the "direction" information, but can use their "warn only when on route" system.
This means that in the case of a single camera which can be spun round to work in either direction, ON A DUAL CARRIAGEWAY; if there was only ONE entry in the database it is likely the TomTom would not register it when you travelled in one of the directions. therefore the decision was made to add TWO icons directly in the middle of each carriageway.

I've often meant to ask MaFt (the database supremo), how this is handled on other machines that CAN use the heading info.
It's probably too late now but maybe there should have been some better indication in the numbering system for when two apparent cameras were really just one.
I'd thought of Gatso:12345 and Gatso:12345A or Gatso:12345.1 maybe?

Or maybe there is already some clever way to strip out the "doubles" on the download for systems that can use the headings, and it just hasn't worked here?

Any words of wisdom MaFt?
