Immer noch unerklärliche Abstürze vers. 321 auf IPhone
-
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
natürlich online,
es geht doch nicht um das sofort neu berechnen, es geht darum dass über fast 2 km an jeder möglichen Abzweigung ich aufgefordert werde abzubiegen oder zu wenden obwohl die Route dann unsinnig durch Siedlungsgebiet mit diversem weiteren Abbiegen führen würde plus Verkehrsberuhigungsbauten und Tempo 30. Erinnere an den Fall Königswinter, wo ich auch anders als zunächst vorgeschlagen zur A 3 gefahren bin und noch 2 km vor der A3 Auffahrt zum Wenden und Zurückfahren aufgefordert wurde und ich dann MRA abschaltete.Je nach Situation ist A-B Routing, nicht nur bei mir bei Abänderung der Anfangsberechnung in der Neuberechnung chaotisch und nicht zu gebrauchen.
-
@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.
-
@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.

@Con-Hennekens
Just back home and as yesterday from the same point the recalulation and proposal is rubish. Not only short after the change. Close to my home I have only to drive over a crossing 250 m straight on, then turn right, no ohter option here, and again for 300 m straight on and then 30 m left to my door.
Proposal from the crossing is turn right and than a route of 1,3 kilometer, the second half through tighter angular roads as my 600 m from the cross. No other Nav Sat do this.
By the way, the first correction is here
Grey is the calculated rout at start, blue arrow my decission to drive and the red turn back the proposed correction.
Problem you cannot drive this way. The last 50 Meters is a dead end street, A One way street only from the opposite end and this for years now.
What is Here doing here. Last year I found a similar situation, the proposal ends in a meanwhile changed Parking ground. -
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

Corjan, to whom is this answer? Me?
I start the route from the menu Favorites, then homebase and did not get such pictures with three options. And my picture present the situation just after passing the cross and leaving the running route and then got this proposal. -

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.

But anaway I wrote about nonsens route recalculation during routing not a selction of three proposal at start..

@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.

Sorry ich schreibe jetzt in Deutsch. Ich kann aus der Antwort zu meiner Problemschreibung von unsinnigen Neuberechnungen bei Routenänderung einer von Standort nach Home Route die schon läuft nichts passendes herleiten.
Ich hatte schon vor gut 2 Monaten mich über das seltsame „fahre zurück“ obwohl längst die einzig sinnvolle Alternative klar war nicht verstehen. -
@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 der Starter dieses Themas war ich und kein weiterer Beitrag hier bezog sich au Scenic Routes. Es ging um Neuberechnung von Routen einfachen A2B Routen wenn man die Vorberechnung und Fahrt verlässt und dann noch hinzu Vorschläge bekommt in Straßen abzubiegen, die in Sackgassen führen oder gar auch im weiteren Verlauf, von mir nicht genannt, Straßen die gar nicht vorhanden sind oder kurz vor Ziel Anweisungen erfolgen die doppelt so weit sind als der eigentlich sinnvolle Weg.
Kurioserweise, bei geplanter Route rechnet die Engine richtig, auch kurz vor der Haustür, aus der gleichen Hauptzufahrt an die Kreuzung kommend. Muss das aber nochmal verifizieren.
Ob das an der Here Routing Engine liegt oder einer anderen Engine (z. B. Grasshopper) die eingesetzt wird, dies ist mir egal. MRA Next hat hier ein wiederholtes Problem, das zu lösen ansteht, will man mit weniger Fehler rechnenden APPs konkurieren.
-
@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.
