Hi,although not being a TT employee I'll try to answer it as best as I can:If the TT device plans for fastest route it does so no matter of the distance. Usually large roads get preferred as they have a higher average speed.If the device plans for shortest route it does so no matter of the time being needed. It may happen that you need twice as long as with the fastest route.The option in between is the eco-route. That means an economic route being a mixture between fastest and shortest route is being chosen. Most of the time it'll be very close to the fastest route from my experience. Time is weighed more than distance concerning the economic part it seems.Also please check your route planning preferences. You may want to avoid unpaved roads. That eliminates quite some of those minor roads. I usually plan for fastest or eco route as I don't like the shortest route either.RegardsLars.

Okay, thanks. You have the latest application and a map that is half a year old. That should not give any problems. Do you have any restrictions set (such as avoid toll ways, or use a limited maximum speed)? Do you remember the route that gave problems? If so, you can try the route using the online route planner:" target="_blank to see if it also gives the issue. 
I have tried using both fastest routes and shortest routes - both have taken me on "shortcuts" across minior roads to cut a corner on a major road.  Not a problem when I have some idea of where I am, as I simply ignore it, but when relying solely on tomtom in a strange (often foreign) country or in the dark, it can be disconcerting to be led up a farm track with no certainty of being able to get out at the end!

Shouldn't there be an option to only use roads above a certain standard?

I would always go with 'Fastest route' if you want the fastest route. 'Shortest route' may take some shortcuts, but will eventually take longer in time.

I see. Which model do you have? See here:" target="_blank. And which application and map version are installed? See here:" target="_blank. Do you have IQ Routes turned on? Do you have any restrictions set, such as avoid toll roads, or use a limited maximum speed?

Okay thanks, so we're talking about a GO LIVE 820. Could you give the map version and application version? Is IQ Routes enabled? Did you set any restrictions?

You can find the version numbers of application and map using the links I posted in my second reply.

I never use the "Shortest Route" option because in one town it guided me though some of the dodgiest back streets I have ever seen :S :D

Which map version do you have?" target="_blank
Thanks for the fast reply, been using fastest but sometimes it takes me through country lanes / back roads not good when i have hospital patients on so i thought maybe i was using the wrong setting.
Ive been using my Go 510 (with updated maps) which i know is easily 6 years old lol, but its never let me down up until yesterday so ive just bought a Go live 820
Its uk maps but i dont know the version, sorry
APP 12.055.1124410.74 (0) (2063,23/11/2012), 0S 1106601


Hope this is it

Hi aspectvic. I have exactly the same question you raise and I see you get no answer. 

I have a VIA 135 and recently had a great trip through France. The TOMTOM was great - except for the way it cuts corners to, theoretically produce the shortest route. 

When I knew what it was doing I could ignore the turn into a very minor road and TT would recalculate the route. OK. But when you don't know to do it it is very alarming to get a narrow country road for ten miles instead of a good main road for 12 miles.

There must be an algorithm that TT can work out that says the savings in time are not worth the effort. If I go on a main road through a right-anglr triangle A-B-C and TT says it quicker to go A-C - but on narrow roads, I'd rather go ABC.

Whay can't TT figure that out and let us chose that way?

I write this comment in response to your year-old comment in the hope the TT will post a reply. But I won't hold my breath.
Thanks for the tip, Lars. I've now set my TT to ECO route. I won't be able to test it on the French route but I'll see if I can find an equivalent back here in the UK. Cheers.
