Inverting a Route

[Mikey]

Hello Zumers,

I have a short route about 100 KM long. I have added the Via and Shapings I would like, and all looks good. When I try to invert the route, BC gives me a message like; 'The route contains one-way roads that cannot be travelled in the inverted direction'

Why would this be, thanks, when the route is a simple, single carriageway, winding, non-stop road?

Help appreciated, thank you, Mikey.

A route point in the travel lane of a road with a median can cause this.

Thank you Peobody.

It is just a simple country road but BC must see something to make it disallow inverting. I accept that and will work around it.

BC suggests I copy and edit the original route. I will have a go at that.

Things like that always intrigue me such that I want to figure out why. I would select the start and end points and tell Basecamp to create a route using them and then reverse them to get the correct start and end if needed. I would then add the other route points in order, calculating in between each in the hopes some weird behavior like a u-turn appears. If not, I would then scrutinize the shaping points in the original once more, perhaps looking at their locations in Google Maps satellite view.

Thanks Peo,
I did check the original route to ensure all Points are in the middle of the road. I then marked its name with ‘final’ in my List. ‘Final’ - Risky perhaps, when unridden, I admit.

I like the approach you suggest and will try that later today.

@Mikey, I am curious whether you were able to figure out what was preventing your route inversion.

Hi Peobody,
Thank you for your interest and my apology for this late reply. I wanted to delve further but limited time has delayed.

I examined parts of the said route on Google Maps Satellite and can see sections of the road that provide dual-lanes for overtaking in one direction while on the opposite side there is a single lane for traffic travelling in the opposite direction. Often in Australia we now have wide painted dividing lines in place of the previous close double lines and maybe Garmin treats these wide lines as a median between two “… one-way roads that cannot be travelled in the inverse direction’. There are some of these lines on the said road route.

I can also see some very wide painted lane separations near intersections too. These appear almost a whole lane width wide. These sections may also prompt BC to treat the traffic lanes as one-way separate, opposing direction roads, and give the warning message.

The ‘cannot be inverted warning’ did not appear when I made short trial routes on parts of the said road (with Start – End) where the whole short route had a single lane each way divided by a white dashed/broken line. For these routes I was able to Invert them successfully.

My claim in my second post above that the road is “just a simple country road” (as most riders may assess) is true in parts, but not all of the route as seen by BC, apparently.

I hope you can follow this.
Cheers, Mikey
