A40 "Blocked" - Map Share is a Disaster!!

They always used to be shown as 'open' roads. Presumably they would be classed as minor/slow speed roads.

Personally I think they should opened up, but you have to be aware of the one way nature of most of them. Not always in the direction that you expect.

If you route to a dotted road, TomTom will navigate you to the beginning of the road and that is all. It will not use these roads as through-routes, though. Some dotted roads are actually farm tracks, others are private roads and still others are the likes of industrial estates. One thing I've noticed is that these aren't consistent; a 'dotted' road on one map (UK & ROI) might be 'normal' on the W&CE map.

So do the maps really need ANOTHER category, to differentiate between 1. perfectly drivable roads like service stations and industrial estates and
2. the un-navigable farm tracks that we hear about on the news when another lorry has got stuck?

Must dig out the old "Colour scheme editor" again to see how that describes the different road types (on a *!*!* Mac today so can't fire it up)

I thought that service areas were marked closed to ensure you followed the signs to the correct parking area and not the actual POI which may be anywhere on site. Also it stops "shortest route" going through the area and the "bear right" alerts that can occur at any time.

You'll find some laybys marked as dotted roads - TT doesn't say keep right. When they're not dotted, TT says Keep right. I find this frequently with laybys which are separated from the road by a kerb or verge or similar.

So are we saying it works like this?

It WON'T tell you to go onto a "dotted" road, but once you have made your own decision to go onto it, then it will start giving navigation you instructions again.

It will, however it may not get the position right. On our company campus (which is quite large) the device likes to place me on the opposite lane of our dotted line alley. Not really an issue though.

In my travels, I often get delivery destinations which are "off road", e.g. hospitals, Industrial Estates etc. When I get there (outside roads) , I get the "You have reached" etc, but the navigation line along the road is still taking me there along the dotted roads and DOES tell me to turn if there's enough road and turnings for it. I think I generally get "You have reached" when I turn onto the road where my destination is to be found whether it's 1 yard or 1/2 mile maybe - coming home, it announces "Reached" as I turn into the road, but then also some distance later announces "After 200 yards, you have reached your destination" and finally "You have reached" when I'm there. You could ask TT, if you thought they'd have a clue! Rolling Eyes

I'm getting the same response as Dennis when going on to industrial sites, if I create a favourite or POI for a particular unit it will continue to give directions after I leave the main road even though it says i have reached my destination at the point the dotted roads leave the main road.

So, from what everyone is saying, all roadways that are not adopted as thoroughfares, laybys, Service Areas and link roads that wouldn't be part of 'normal' navigation, would be better marked with a dotted line.

Known as Not Normally Accessed Roads. Smile

I can see a certain logic in this as I have been routed through a large layby before now. Rolling Eyes

If you do access such an area, the unit will just recalculate as you exit.

I would have thought, however, an Industrial Estate would be classified as being part of a navigable road.

Just did an experiment.

Generally the Travel Via, to a Service Area, works well.

The North Bound Services at Toddington on the M1 gave some unexpected results though. So be careful!

I also noticed that the speed drops to Walking Pace, which would keep you out of the area for general navigation anyway. Smile
