Emery Down to Lyndhurst navigation (UK)

MartinC — Fri, 23 Mar 2012 22:06:02 GMT

Hi,

Can anybody out there help me out on this...?

Go Live 820 (Map UK v8.85) navigates a 6 mile route from Emery Down to Lyndhurst rather than the 0.8 mile route that any sane person would take (onto the A35 at The Swan Inn).

There are no blocked roads or turning limitations. Have tried blocking all but the 0.8 mile route, but then it just can't find a route at all. It's like the road has a gap in it but I can't find one to manually overide.

Have also noticed that the TomTom website route planner does the same.

Thanks

Martin

Easiest answer: TT c.cked it up.

TT online planner even can't find the address, when you type it correctly.

With incorrect spelling, it offers the correct one...

Assume in TT's database the road on the shortest way is considered as private or blocked, therefore detour "offered". Yet can't work out the round trip in Lyndhurst...

Yes, and starting south of Silver Street navigates the long route but starting south of the next junction (Unamed Road) navigates the short route. No turning restrictions are showing for the "Unamed Road" junction, the road appears to be continuous and the road type is Minor. Can I overide this on my SatNav?

My previous Mio didn't have this problem (but it didn't have HD Traffic).

By the way, have you tried after the route calculation to do the VIA this-and-that road option?

I will drop the link to Shorty, hopefully he can get this one sorted for the next update.

I'll certainly put this in an MSR report for you but will also contact the Production Team Head for the UK,by mail.

I have a similar situation from my home to our (RSA-local HQ). It's closer to the central (soon to be tolled) highway from my gate than it is via the other better highway un-tolled. So I initiate my route at the Western end of our street.

In your case however it's not a question of virtually the same distances but could be one of Road classification. If you use Fastest Time then normally the router will choose the highest category of roadway keeping you there for as long as possible. Using Shortest Distance may cure the problem. I have sometimes found in cities that a combination of fastest and shortest t works quite well.

Would you please try the different algorithm and let us know. If it still routes the round-about way then it means that there is a discontination along that way or a difference in classification.. Can happen but it's a c....k up as Zsoldt put it and we'll have to go into the raw detail to create the fix.

I regard the internal lanes in the gap as suspicious (Bournemouth to Emery Downs).. Are there gates perhaps at each end. It could be a road classification error in that the through road is not an alley but an acceptable road not encumbered by gates and so forth but is shown as such in the map.

MartinC,

FYI There is a section in this forum called 'Map Quality'

Re: Emery Down to Lyndhurst navigation (UK)

Shorty,

Thanks for the reply.

I have tried different algorithms as you requested... Shortest gives the long route but Walking and Cycle give the short route.

There is a cattle grid (always open to traffic) around where the problem happens, so this may well be on the map as a gate and be causing the issue. I don't have any problems navigating over any other cattle grids in the New Forest.

Cheers

That could well be the cause of the problem Martin and perhaps the others that you've encountered are not marked as a non-navigable digital gate. Let me check with the UK Production Team and get back to you.

Good afternoon Martin,

There's a similar discussion going in the Map Quality Forum so perhaps we all should switch to that http://discussions.tomtom.com/t5/Map-quality/Poor-maps-for-East-Sussex/m-p/179373/message-uid/179373#U179373

@MartinC: Just wanted to drop a quick note, the report had been accepted for this correction (ID: 04294462-e2dc-102f-a4c7-62c3ad176ad2). Not sure though if it will be in the next update or the one after.

Re: Emery Down to Lyndhurst navigation (UK)

Thanks for the update. No change in navigation behaviour in Map v8.90, so I guess I'll have to be patient for another 3 months.

Martin

Re: Emery Down to Lyndhurst navigation (UK)

MartinC — Fri, 31 Aug 2012 20:44:16 GMT

Have been patient, but unfortunately no change in Map v8.95.4441. Please could somebody provide feedback on whether any change has been made?

Thanks

Martin

Bump.

Can anybody shed any light on this... has a map correction referred to above been made, but not solved the problem (on the website or device)? Could this be recified in the November(?) update?

I'm hoping that this particular navigation quirk will not prove to be permanent.

Cheers

Martin

In the 895 it is still in. Hopefully the next update will include it.

Zsolt,

Map v900.4603 installed and issue not resolved.

Shorty,

Has MSR abce5d20-cbef-102f-8665-e83f81ca73e1 submitted on 30/03/2012 been applied to the map? If so, then it hasn't worked. If not, then when will it be?

Many thanks

Martin

:( It would be really time now to get it sorted.

I have just found out....a section of road over the cattle grid that is mentioned earlier is marked as 'No Through Traffic"...this is the reason you cannot route over it. It therefore looks like it has been incorrectly marked as a Private Road in the map data.

Re: Emery Down to Lyndhurst navigation (UK)

Zsolt — Mon, 26 Nov 2012 16:41:36 GMT

Then it should be an easy fix I assume :)
