Quality of TomTom Premium camera data

(This and subsequent replies split from THIS topic as it was drifting well away from the original question (now resolved))

I am sure that TT only provide the Safety Cameras for the comedy value, best to disable the alerts from the TT cameras and use the ones from here.

They're not false alerts though and that is the fault of TomTom and not us for not allowing us to offer directional alerts.

It is my experience and the findings of many others who compare the data regularly that there are many more issues with TT's database than your summary suggests.

Coverage of mobiles is one example as I have witnessed on many occasions. I have passed at least half a dozen live mobiles that my 940 knew nothing about. Given they are the sites MOST likely to catch you then it makes the TT data pointless and I'll take the non-directional warning issues over a missed mobile any day of the week.

Another is database currency. Time after time I have come across cameras that TT have yet to add or cameras that have moved or been removed yet TT still report in the previous locations. So much so that I simply wouldn't trust their data full stop.

Even your experience suggests our data is as good as RA/TT. We are cheaper and release more regular updates on top. But I'd argue we are a great deal better, as we should be given our data collection mechanisms which are far superior to RoadAngels.

TomTom' had a head start at the outset because it was quite clear that they harvested our data. But their head start hasn't helped them keep the data uptodate

When it comes to mobile sites, obviously 99% of the time they won't actually be there.
So... If, as you say:

As I said, it's just my experience running Tomtom and PGPSW on my Inforad K1 side-by-side.

I don't have any vested interested in either. I'm only speaking as I find.

Don't forget mobile cameras get you in both directions. Alerting in one direction ony is useless for mobiles.

I do approx 40k a year and the TT database for specs and mobiles is so far out of date it is comical.

I can't give exact locations, but they are still reporting specs cameras on the M6 that were removed many months ago, and don't have ones added that have been there for more than a month.

I ran both sets of (PGPSW and TT) at the same time on my XL LIVE for 3 months and can't remember a false alert on PGPSW (except directional), the TT had numerous on each trek up and down the motorways. Any missing cameras from PGPSW were always in the next release.

Just my personal experience.

Even if I wasn't a camera verifier, I think would be rather nervous if I went past a camera on the other side of the road and didn't see and hear it on the TomTom. It just gives me the confidence that nothing is missing.





(As there as more posts on the quality of TT's data than there were on the original (now resolved) question, I'll split them off to their own topic.)

[AndyVaughan]

Boy that confused me - I just noticed a thread I didn't recall starting

[uk89camaro]

I've never used the TT database so can't comment....technically that makes me off topic..

Another vote for PWGPS, very rarely an error, but directional alerts would be nice. However as a previous poster said, I can put up with that for accurate mobile alerts.

Wasn't always the same though, I went a couple of years with an origin B2 at an ourageous amount of money, as the first versions of this database were pretty poor.....I suppose as you might expect.
