Map Error help?

C2k3 · Posted: Tue Dec 02, 2008 2:50 pm Post subject: Map Error help?

This has been an annoyance for years.

There is a road that is the shortest/quickest for me to many places, but TT sends me 6 miles out of my way.

I recently ditched Navigator and bought a 720, upgraded to latest map etc. I hoped I could do the Map Correction myself or just download someone elses correction. Oh no. No chance at all, unless I'm missing something.

Here is a link to driving instructions on Google Maps which illustrates the problem (hope it works!):-

http://maps.google.co.uk/maps?f=d&saddr=51.136985,-0.262985&daddr=Partridge+Ln&hl=en&geocode=%3BFVhGDAMdTfj7_w&mra=dme&mrcr=0&mrsp=0&sz=17&sll=51.136049,-0.263039&sspn=0.00482,0.012982&ie=UTF8&z=17

The distance between A and B is around 100yds, the suggested route is around 6 miles! It's exactly the same travelling in the other direction.

If you move either of the place marks towards each other the error corrects.

I have reported this through TT several times over the years.

I've just reported again through TeleAtlas. The response:- "We apologize, but due to the general nature of your report, we cannot define specific updates to our map database to address it."

I take this to mean that nothing will happen because it's a tad awkward and someone might have to look at a slightly deeper level!

Any ideas or insight guys?

I can't even determine the nature of the error - maybe I'm reporting it wrong and don't know the magic technical words. Maybe it's "a double ended loop-load data control error" or something silly. Smile

It's irritating having to plan an itinerary passing through the middle of this 100yds of road whenever I travel in that direction!

Cheers

Has the small piece of road that isn't used between points blocked at all?

Is it a gated road?

Looks really strange, and slightly amusing. Obviously it isn't funny if it affects you, but to see it in "Reality View" is rather peculiar!

Can the people who live there navigate from their front door using a Sat Nav? Who knows?

Cheers

It does seem a little strange - as you say, there's nothing obvious to indicate why it won't use that particular section of road. If you haven't done so already, it's worth submitting as an "Other error" through Mapshare, or raising as a specific incident with TomTom Support, saying that you can't see how to change it in MapShare, and asking why this section of the road isn't used in navigation.

You probably won't get an instant answer, but it might just raise the awareness of the issue.

Nope, it's not 'gated' and has never been blocked, it is all one through-road. I use it at least 4 times a week and have done for years!

There is only one house on that stretch - I don't know them but there is frequently a police car parked there - I'm sure the Police use SAT Nav.....

One of the problems certainly is that the categories of reporting errors don't fit this one!

Most odd.

Just an update from myself, I thought the road was blocked by mapshare, but its not blocked on my unit. Checked all roads around that section, all open and usable! Even did the same pretend route and even on fastest route, still came back as the 6 mile version!

Yes. It's certainly not the people in the one house pulling a fast one and reporting it blocked!

This issue has been happening since TT5 for me!

That section of Partridge Lane shows on the Google map as a thinner line than the rest of Partridge Lane. Presumably this means that it is a different road class. The tomtom will use it as a bycicle route or walking route but not as a car route. If the route starts in the middle of that section of Partridge Lane the tomtom is happy to navigate along it in either direction.

Just had a go a a few things also...

If you set a "Go via" in the middle of the road that's missed, it chooses it fine Shocked

- 200 yds in 20 seconds. So it's not a road speed error or turning error.

I've even tried it without IQ routes just in case - makes no difference. It has to be a mapping error but I can't see where (I can usually at work out what the error is!).

My conclusion would be that the Time to Travel data is incorrect.

If it has been set to 20 mins, instead of 20 secs, then the quickest route will be the 18 mins, 6.4 miles, journey.

This is not the first time this has happened, and there are probably more dotted about that haven't come to light yet.
