I didn't mean to slag off train at all. I was just intrested about how to help it correct these small mistakes. And how with all that data gathering tech they still get it wrong. 90% of the time I can't fault it, and the other 10% it is only a small irritation with a bit of common sense it is obvious which way to go. I am looking forward to the map share article

We have just posted the second article in the series:

Part 2 MapShare Community input
This is the second in a series of articles that examines the intricacies of creating and maintaining digital maps by TomTom. This article looks at the TomTom MapShare community led added value to the base map.

I'm still not convinced about Mapshare. Ever since it came out I have submitted some changes that happened in my home area. Two places where roads were "sealed off" and traffic unable to access the main road due to bollards placed there and a case of two roads being confused name wise. One is Ingram Crescent West and the other Ingram Crescent East. The west one has a number of section named as the East. I have sumbitted this change on every map update I've had but still its wrong on map 895.

About time Tomtom got that act together. Missed once or twice is acceptable but several times a year is unforgiveable in my eyes.

This series on digital mapping is fascinating. Well done.

My question is, when other Sat Nav providers (thinking of Sygic's Android app here) say they use TomTom maps, are they getting all this info and updates as well?

That would be depending on what they pay for, wouldn't it? Still it's a great topic to generate 3 or 4 pages of unsubstantiated speculation about Confused

Very interesting article on the MapShare.

I joined MapShare long ago and only download"TomTom Verified" corrections. But like the author states, I too have to repeat the corrections a few times with one area which I would say extremely important.

This would be M6 Northbound at Junction 11.

If you set your TT not to route through a Toll Road. TT will advise you to leave at Junction 11, go up the slip road, take 2nd exit, which actually brings you back onto the M6 to continue North.

I keep telling TT that there is no Toll at M6 Junction 11 Northbound and you do not need to exit the Motorway but there is nothing you can do on your TT to eleviate this and they do not update this section.

I travel this route at least 3 times a week for the past few months and whilst I know not to leave the Motorway, motorists who rarely travel the route may not know and think "what the..."

Whilst I appreciate the vast amount of data TT receive daily/weekly. I think it is important when it pertains to a Motorway.

I haven't checked, but I understand they have corrected M6 junction 11 in the latest map which came out earlier this week, v895.

Hello,
When the next article on IQ Routes ?

MikeB

Sorry for the delay to the next article, I wasnt feeling too well last week, It should have been published on Friday... Anyway better late than never:

Part 3 IQ Routes for improved routing
Having discovered how the basic maps are made and maintained we now turn to some of the more interesting innovations that TomTom have added to their maps. The third article in our series of How TomTom make digital maps looks at routing. In particular I am looking at the IQ Routes technology that TomTom introduced a few years ago in an attempt to ensure that users are provided with the best routes possible.

The forth article in the series has just been released:

Part 4 HD Traffic real time traffic information
In the previous articles we have seen how the geometry of the map is created, then the attributes for each road segment have been added. With IQ Routes each road segment was assigned a 'real speed' based on historic average speeds in 5 minute intervals. Now with HD Traffic we can see how these IQ Route average speeds can be dynamically updated in near real time with actual current road speeds.
