Automatically skip waypoint

Richard 18

If you miss a waypoint, how quickly should the route skip it and not try to send you back?

Thank you.

@Richard-18 That depends on several factors. See this post where developer explains how it works: https://forum.myrouteapp.com/post/25537

Thank you.

I simply asked as yesterday, coming back northwards from Le Mans on the motorway, my route (with all the waypoints in the correct place) several times refused to recognise that I had successfully and correctly, driven through a waypoint.

It was looking to me like the app thought I hadn’t passed through the waypoint but then didn’t skip it. Instead, it recalculated my route, to exit at the next junction, to drive back south on the motorway, rejoin the north carriageway and pass through the waypoint.

Surely, on a very simple motorway, the app should just skip any waypoints it thinks the driver has missed?

Richard 18

Does anyone have an explanation as to why, when the app thought I had not passed through a correctly placed waypoint on a motorway, the app did not obey the automatic skip waypoint function, but instead kept trying to send me back, to pass through the waypoint agsin?

It did it several times.

@Richard-18 I don't know what your route looks like. Please post the route here so that it is publicly accessible.

It was a very simple route, 9/10’s motorway from Arnage / Le Mans to the Eurotunnel at Calais.

Why the app thought I had not driven through the waypoint is a mystery. Why it then did not automatically skip the waypoint (instead of recalculating to send me back down the other carriageway) is also mystery. It had this problem I would guess four or five times.

Rob Verhoeff

@Richard-18 I have no clue! Route seems to look okay. Some waypoints are slightly off route, but not that far that they should give a problem I think. I probably used about 15 waypoints in total. But that's my two cents.

@Rob-Verhoeff

Thank you.

I would normally use far fewer waypoints. I only filled it with more points (using Gold’s ‘Expand’ feature) as I read on the forum, the advice to expand the number of waypoints to something like one every 5 km. I did it as any experiment, as much as anything else.

Unlike a complex route on conventional or smaller roads, where It would be easy (either accidentally or on purpose) to miss a waypoint, I would have thought it was very difficult or even impossible, to miss a waypoint on a motorway. I am sure (or I am as sure as I can be) that I went through the waypoints, but for some reason, the app thought I hadn’t and the automatic skip function didn’t seem to work.

Like you, I am at a loss to understand why the automatic skip function didn’t work. Seemingly, nobody has an answer.

PS I’d be interested if you could identify for me please, which waypoints you spotted that are off the route.

The 'forcing back' to a passed route point also happened to me (once).
And that was a point that I was able to successfully pass earlier that month and later too. All this without changing my route and waypoints. I was navigating off-line.
Since an update had taken place in the meantime, I assumed that this fixed the problem. But it apparently persists.

Nr's: 2, 20, 38 and 45. As I said before, I can't imagine that these points really should give a problem. For myself, I place them spot on the black line as you did with the others.

@Rob-Verhoeff

Thank you, Rob

Whilst those were not points that caused me a problem, I agree that their proximity to the black route line should not cause a problem. In a way it’s no different to being on a four lane motorway in lane four, when the black line happens to be along lane one.

Even if it were the problem, surely the app should still automatically skip the ‘missed’ way point and not recalculate to take you back?

Rob Verhoeff

@Richard-18 Agreed.

@Richard-18, check this thread from here, to gain insight on how auto-skipping works:

Thank you, Con.

I am not sure that driving along a simple motorway, as opposed to a relatively complex non-motorway route, matches the example in the link.

As I explained, I am sure that:

A. The waypoints were placed accurately on the motorway carriageway. This has been confirmed independently.

B. As I did not leave the motorway, I must have gone through the waypoints, surely.

Why then:

Did the app think that I had missed the motorway waypoints?
Did the app then recalculate, to take me off at the next junction, send me back down the other carriage way, to the junction behind me and then come back up the carriageway, to pass through the waypoints again? This happened more than once.
Didn’t the app automatically skip the waypoints it thought I had missed?

If someone can give me a simple answer to these three questions, that would be great.

Richard 18

I guess nobody can?

Corjan Meijerink

@Richard-18 Sorry for the delay.

Missing waypoints can occur if GPS signal wasn't available or inaccurate for a longer period while approaching the waypoint.
Skipping waypoints automatically is only triggered at the second (or more) deviation. Then the first next nearest waypoint is chosen but that can very well be the waypoint that's behind you. If you seem to continuously ignore it, the app will skip it anyway after 6 recalculations. On highways it takes quite a long time before you can turn around (which you ignore) and thus before a recalculation is triggered. It might indeed then be a good suggestion to alter the algorithm to be more aggressive in skipping waypoints on the highway.
See above

Hope this helps!

This is exactly what I sometime earlier mentioned regarding the old nav app's algorithm being triggered by ignoring instructions on long stretches of road, instead of actual distance from the previous and to the next waypoint :). You were able to word it better haha :).

@Corjan-Meijerink

Corjan, many thanks. I now understand it.

I agree that an alteration to a more aggressive skipping of waypoints on the highway would be beneficial.

I had the advantage as I was in a car, riding as a passenger. I was therefore able to watch the display on the phone, whilst the car drove up the motorway. I knew that it would make no sense to leave the motorway, drive back down the other carriage way and rejoin. I just couldn’t understand why the app would tell me to. As I was a passenger in a car, it was easy to ignore the app’s instructions.

On a motorbike, on unfamiliar roads (even a motorway) it might not be so easy, especially if the user of the app was following the instructions blindly. That is why I agree with you, about making the algorithm more aggressive on highways would be a good idea.

Your explanation answers my question. Thank you.
