Now most people are upgrading to the new 6.140 firmware on the Tom Toms would it not be possible to have the gatso/truvello speed camera database split into there own groups. There are now 100 POI allowed on the Tom Tom and I for one would like this option. |

Begs the question - why? |

For me, all I care about is the speed a camera is set to, I've often wondered why anyone cares who made it?
Just interested to know... |

Only difference I can see is that with Gatso you can brake down to the speed limit about 30 feet later. But we never use the database to allow speeding do we? |

Er, at risk of being flamed for repetitious posting . . .
A Truvelo is sited to "get" you as you approach it - and some of them have a b****y long range.
A Gatso takes photos of your rear end (actually your vehicle's rear end cos if you're sitting in a car it would be difficult to see your rear end!)
BTW. Has anyone else heard anything about Gatsos being 'linked' so that they act as average speed cams? I recently met someone who claimed that he had been caught for speeding in a motorway roadworks zone for exceeding an average speed. I am very familiar with the place where he claimed to have been caught and there are only a series of 'Gatso-like' devices. His comment was along the lines of "I slowed down for every camera over the white lined area then accelerated until I saw the next camera then slowed again - but was still caught". Now, I don't want to appear to be sanctimonious, but I've no sympathy for him as the limits are imposed to help protect the lives of the workforce and an average speed of 86 mph is almost certain to put lives as risk. (OK, rant over :D :D ) _________________ Colin |

Specs are now routinely used on British motorways when roadworks are in operation. Slowing down for Gatso lines on the road won't help your friend if he doesn't look out for the specs masts on enetering and leaving the roadworks. There is usualy a sign warning of average speed cams in operation as well. |

That would be a bit sneaky - having both Gatso and specs cams on the same stretch of road. But I suppose the fact that our customer had been doing well over 80 mph in a 50 mph zone demonstrates that they were needed! _________________ Colin |

I always thought that Truvelo had a very short range. It doesn't have any radar, but reads the speed from sensors embedded in the road in front of it. The actual photo is then taken as you cross the three white lines just after the sensor. Every one I've seen is only a short distance from the camera. |

It also catches the driver who enters an average zone, gets stuck behind slow movers and then speeds knowing that on average, the speed will be ok. If you have a vehicle system which displays average speed, you can trip it at the start of the specs and as long as your average doesnt go over the limit, specs isn't interested. Gatso will get you, however, if your speed fluctuates up and down. |

Yes the truvelo works on pressure strips (aka the white lines) which are just in front if the camera, so no radar and no long range... |

The actual sensors are embedded in the ground before the white lines., and appear as lines of bitumen, where the slits have been filled in. Having measured the speed, the Truvelo knows when your front wheel will cross the 3 white lines, and takes the picture at that point. That way, if there are 2 vehicles in the picture, the one with the wheels on the white lines is the one which had the speed registered. |
