Immer noch unerklärliche Abstürze vers. 321 auf IPhone

Peter Schiefer

es gibt immer noch Abstürze auf iPhone auch wenn MRA zumindest nicht gewollt benutzt wird.
Keine andere Navi App die ich nutze hat ein solches Verhalten.
Hinzu, gestern von irgendwo Favorit „Nach Hause“ gewählt, also einfaches Standort nach B Routen.
Dann die Route abgeändert, während Apple, Google Sygic sehr schnell die neuen von mir angedachte Route berechnen und übernehmen, brauchte es bei MRA fast 2 km bei der ich dauernd zum Abbiegen oder Wenden aufgefordert wurde ehe die Route „passte“.

Irgendwie ist bei MRA noch nicht alles perfekt.

@Peter-Schiefer, Haben Sie das online oder offline gemacht? Bei mir in allen Fällen immer eine neu berechnete Route innerhalb ein Augenblick....

Con Hennekens

@Peter-Schiefer, OK, das habe ich anfangs falsch verstanden. Ich werde später versuchen, einen Test mit einer A2B-Strecke zu fahren, und dann absichtlich "falsch" zu fahren.

@Peter-Schiefer In general, I have found AB routing in MRA to be less than optimal. The last time was from the trip home from my BMW Dealer. I know the area like the back of my hand, but I was curious what route it would produce. Upon seeing where it wanted to take me, I chuckled and stopped the route immediately.

MRA is great for creating your own routes. But Google/Apple Maps is a much better choice for quick AB routing. Use the right tool for the job.

Con Hennekens

@John-S-Parry, While I agree with "the right tool for the right job", and use GMaps a lot myself, I have never seen MRA A2B routes fail like is described here, and I have been testing that quite a lot.

Wouldn’t call it rubbish but I can understand the confusion. It’s a choice we constantly consider.

You select a destination and get 3 different routes.

You then choose the one you like (middle option, B, for me now). I know the area but ignore that, I want this route.

The first displayed option is the fastest but goes in a whole different direction. Important detail!

If I’d do a u-turn in my car and get a recalculation, there are 2 scenarios:

stick to selected route (I selected B)
pick fastest (option A, not my selected option!)

So there we go, what do you pick?

At MRA, we do the first option so you stick with the selected route. With the philosophy that we picked that route with a reason. Is that ideal? No, not always.
Is it something we did with a reason? Yes!

You’d enjoy to immediately get the new, fastest route. But then another day, you might not

@Corjan-Meijerink Great explanation

@Peter-Schiefer said in Immer noch unerklärliche Abstürze vers. 321 auf IPhone:

I did not get such pictures with three options.

Yes you do. Except when you already are close (few kilometers) or there are no feasable alternatives. Pick a favorite a bit further away to see how it works.

@Corjan-Meijerink, if we pick the most left (fastest) option out of the three suggestions, does it then also try to stick to the chosen route? I think it is a great feature, if you choose one of the alternatives explicitly, but when choosing option 1 it is like "I want to get there quickest way and I don't care how". In that case the logic of an explicitly chosen route probably does not work.

But I have to admit, that in such cases usually I use GMaps anyway. It has better traffic support and that's more important for me when visiting customers for example.

@Con-Hennekens yes it does

@Con-Hennekens I just mapped a A2B route of 100-miles across Los Angeles. The LA basin and surrounding areas are a snake pit of freeway choices. There a 5 major freeway routes from which to choose. There are also too many permutations to count. Usually, the deciding factor will be comparative traffic between the different choices.

I just did a compare of MRA and Apple Maps for recommended routes. Apple showed the fastest 3. The top two show identical in time, but slightly vary in distance. The third lags by about by about 20 minutes. MRA showed 1 choice, which was the fastest/shortest that Apple presented.

I was surprised that there was only 1 minute difference between the MRA and Apple routes. My experience has been that Apple (and Google) are more traffic aware than MRA, and almost always show a more realistic longer estimated time.

Corjan Meijerink

@Peter-Schiefer my answer explains why it recalculated like it did.

Even if you did not see alternatives presented, the reasoning is still the same.

Con Hennekens

@Peter-Schiefer, I completely understand Corjan's reasoning, especially considering the origin of the app: "scenic routes". However I must admit that "sticking to a route" in my opinion is not very sensible if you ask just for the quickest way to somewhere.

Con Hennekens

@Peter-Schiefer, Die Konkurrenz ist nicht direkt mit Navigations-Apps die A2B-Routen sehr gut abfahren. Der Markt dafür ist schon lange gesättigt, und es gibt sogar sehr gute kostenlose Apps dafür. Das ist nicht der Markt, auf den MRA abzielt. Abgesehen davon stehe ich zu der Commentar, die ich oben gegeben habe.
