I searched around to see if there were many finds for 'dead end' and found none that addressed exactly what a driver might be able to do when they have encountered one. So here is a somewhat lengthy rendition of what I have discovered -- using the simulator ONLY. I would not expect the real world operation to vary from the simulator in any significant way.
My concern here is with having a route with multiple waypoints established and a route plotted between them with one of these waypoint located on a road that is shown as a through road on the map but in reality is a dead end. The dead end is located just a short distance from one of the waypoints on the road.
SIMULATOR SET UP.
I have chosen for my first test a road that I found mapped as a through road under my nRoute map City Select V6. This road is named Tom Moore Rd and is actually a dead end with the dead end located at N 35 46.688 W085 36.087. I developed a trip as follows;
Start point at N 35 37.464 W085 35.495 as 0001 test
Mid Point at N 35 46.688 W085 36.087 as 0002 test
End Point at N 35 46.688 W085 35.330 as 0003 test
As shown in this graphic
The graphic (first one in the thumbnails below) shows the route starting on Rogers Rd turning onto Tom Moore Rd (a dead end), reversing at the dead end and returning to Rogers Rd to complete the route.
The assumed execution of this route has the driver – after turning onto Tom Moore – realizing that it is a dead end road (the route was planned by someone other than the driver that had a peverse sense of humor.) With the realization that the road was indeed a dead end the driver needs to correct the route in the simplest and quickest way possible so that he can get on to the the destination point 0003 test.
How does the driver do this?
From the main menu click ------ Where To?
From the first sub menu click --- Routes
Since the waypoints on this trip were cleverly selected to produce a route named – 0003 test from 0001 test – which appears at the top of the route list ---
From the second sub menu click --- 0003 test from 0001 test --- to highlight it. (Actually is should already be highlighted.
Click --- Go!
If sound is turned on Jane will speak and nothing more will occur. You need to turn on Simulate Route so ---

Click --- Done.
This brings up the 3-D view of the route

Click --- Tools
Click --- Simulate Route
This launches the simulator on the 3-D screen. Then before the vehicle reachs the intersection that produces a loop back on a 'road' (no name)
Click --- Menu
Click --- on icon third button in the three button group shown below
Sorry. Again no graphic. This one (second thumbnail below) refers you to the third button in the Stop, Detour, third button group at the bottom left side of the screen.
Click --- Edit
Click --- on the offending waypoint here 0002 test
Click --- Delete
Click --- Yes
Click --- Done
Click --- Back
Click --- View Map
From here you can observe that Mobile PC has reversed the direction of the vehicles travel.
Depending upon where on Tom Moore the vehicle is located at the point the deletion routine is exited, Mobile PC will loop the vehicle around the’ road’ to the north or U-turn the vehicle. The intersection located at N 35 47.028 W085 35.918 that allows a right turn onto ‘road’ and a loop back to Rogers Rd defines the difference between the loop and the U-turn. Past this intersection Mobile PC executes a U-turn and drives straight back down Tom Moore Rd to Rogers Rd. I am most pleased with the U-turn operation. Maybe not so pleased with the loop back ‘road’.
UNACCEPTABLE ALTERNATE ROUTE?
If the loop back ‘road’ presents the driver with an unacceptable route (gravel with grass between the wheels for instance), I did not at this point know a way to cause Mobile PC to NOT use it while the simulation is active. See below for what I did find that corrected this problem.
What I did try and what failed were;
Adding the loop back ‘road’ to the exclusion list while driving (simulated) on it does nothing.
Adding the loop back ‘road’ to the exclusion list BEFORE turning onto it (simulated) does nothing.
Stopping the simulation ends everything. The route must be started over from step 1 above (i.e. at 0001 test).
COMMENTS
It appears that once the route has been set, road exclusions that are added are impotent.
Starting the route with the exculsion already set still allows the excluded road to be used to correct the route as done above.
Deleting the route and rebuilding it with the exclusion already set makes no difference. With 0002 test being deleted before the loop back ‘road’ is reached Mobile PC still uses the EXCLUDED loop back ‘road’ to return the vehicle to Rogers Rd.
Trying to exclusively use the Shape Route feature of Mobile PC instead of waypoints does not work either. Once the Shape Route routines have been exited you can only Delete All of them.
SUGGESTIONS
The simulator needs a Pause function. We on the road types often stop to make changes. The simulator should allow for this.
An excluded road should be excluded --- PERIOD. No vehicle simulated or not should be allowed to traverse an excluded road or area.
NOW FOR SIMULATED ROAD TESTS WHERE THE ROAD IS MAPPED AS A THROUGH ROAD AND THE ROUTE IS MAPPED RIGHT ALONG THAT THROUGH ROAD WITH WAYPOINTS ON THAT ROAD--- BUT THE REAL ROAD HAS A BRIDGE OUT OR IS DEAD ENDED BY ANY OTHER CONCEIVABLE PHYSICAL EVENT.
Ideally the driver, when confronted with this type of circumstance, would want to simply delete the waypoint(s) that drag the planned route down this now impassable highway and with that, Mobile PC would recalculate the Active Route using the remaining waypoints and destination. Mobile PC would reverse direction back to the begining of the now impassable road and resume the route along a different path.
This effectively asks for the ability to mark a road as excluded while in the middle of driving on it under an Active Route and having Mobile PC recognize that since the road has been used up to the point of the obstruction, it can use it in reverse order to bypass the obstruction while using the remaining waypoints.
I built the following route;
0004 test @ N36 38.465 W084 20.209 as the Start Point
0005 test @ N36 38.613 W084 15.449 as an intermediate point
0006 test @ N36 43.625 W084 10.143 as the End Point
The route and comments are shown here ---
The graphic (third in thumbnail list) showed the route as a through road. I have attempted to travel this road and found it to deteriorate into high grass between two gravel ruts terminating in a dead end about half way to 0005 test.
Note that there are no loop back roads available between 0004 test (under the auto icon) and 0005 test.
Launching the route 0006 test from 0004 test and following the same logic used above for finding out that your route is impassable and using the deletion of 0005 test with continuation of the route after deletion shows that ---
The route is resumed at the point on the map where 0005 test was deleted. 0005 test is still shown on the map with the route still passing thorough it. There was no U-turn requested. Now what?
I then attempted to use the Shape facility of Mobile PC. This worked. Note the trip is still active.
I pinned the route behind the vehicle on the road past the point at which the vehicle had turned on to the dead ended road and generally in the direction of a suitable route revison. I then returned to the map view. The vehicle had turned around and was tracking back toward route 1470 then to route 92 and on to the destination without 0005 test being involved in the route.
In this case it seems that deletion of the unwanted waypoints PLUS choosing a pinning point or series of pinning points (not tried) is what is needed to redirect the route along a path that eliminates the deleted waypoints.
I then noticed (Thumbnail #4 below) that 0005 test still appears on the 3-D view as the simulation proceeds. 0005 test is orphaned as far as the active route is concerned. Though still in the Favorites list it no longer was affecting the modified route.
This is a tolerable work around since it only requires the addition of pinning somewhere behing the vehicle to get the route reversed and recalculalted.
I just hope that when I get to testing it on the road it does the same.
Let me test this pinning operation in the simulation mode on the 0001 test, 0002 test and 0003 test route that had the loop back 'road' on it (thumbnail # 5 below).
Yes. Pinning behind the vehicle immediately after deleting 0002 text did the trick.
There may be other ways of doing this. I tested Detour on the 0004 test to 0006 test route. It failed to correct the route.

There may be other ways of doing this. I tested Detour on the 0004 test to 0006 test route. It failed to correct the route.
Why not just use Menu-Tools-Route Details-Edit and delete the offending waypoint. Mobile PC will recalculate the trip immediately (even in Simulate mode) without that stop and you can continue merrily on your way even if it involves a u-turn. Or am I missing something?

On my route 0001 test to 0003 test under simulation the route continues around the loop back 'road'. My technique immediately reverses the route.
On my route 0004 test to 0006 test the route continues onward through 0005 test and arrives at the dead end. My technique immediately reverses the route.
