Route Here Map

[Cookie On Tour]

Hi,

this is no complaint, and I already posted a similar question but played around and now have a new wired example:

Startpoint:

Kohlscheid Feldstraße, Roermonder Straße, 52134 Herzogenrath, Deutschland
50.835918, 6.077211

Finish:

Lehnsherrenstraße, 52072 Aachen, Deutschland
50.835320, 6.048310

First no difference when changing fastest to shortest and vice versa. None of the routing models do make a change in how they would route!

When using the same Finish and the Start as an ad hoc navigation (so being at the start and start an unplanned route to the finish -A2B regular navigation), and even being closer along the route to the finish, that TomTom or OSM is uggesting for their routing, Here is still trying to navigate "his" route instead. Not choosing the alternative route TomTom and OSM is routing, although their route is faster and shorter.

Sometimes, Here is weird and makes no sense to me on how it is routing. So, what is Here preventing to take the roads TomTom and OSM are taking? I have not set any exclusions of roads. And there is no special kind of rural community that would not allow driving!? Any idea? I just want to understand, why - to probably prevent me using Here at areas that I may not know and would result in confusion.

I don't give a d*** what maps tell me where to go. They all have their own weird algorithms in a black back box, so "nicht ärgern nur wundern" and make your own routes

I know, what you mean, however, it's kind of scary when you trust your navigation system and if you are unknown to an area and want just a quick route to a destination.

What me wonders is that even driving the route TomTom and OSM is suggesting and having Here turned on, it is asking to make a uturn even if you are beyond the point the way back to Heres route would be longer in time and distance.

@Cookie-On-Tour I compared hunfreds of routes HERE <> TT <> OSM and my conclusion is, that now single map direction algoritm is perfect. In my analyses there is no clear "winner". That's why these map directions are not leading for me, but guiding. Also in places where I have never been before. There is no single route I have, that I haven't changed. Not perfect, but suitable for me, is the Michelin Overlay map, in combination with Google Streetview. But hey, that is one of the nice things of travelling your bike: expect the unexpected.

I've often found myself on meaningless roads in unfamiliar places (I use a Zumo XT2). It's nice, but depending on the situation, it can be annoying (rain or little time to travel). Now I'm trying to create the route with OSM and then send it to the Zumo, first going through TripManager. I also upload the track and always check the display to make sure the route matches the track. When I'm traveling, I often check that the route is the right one by opening the screen to the entire route.

Yes, it's a different story, planning and ad-hoc navigation. I need both, but don't want to use multiple apps - but at the end I do.

I tested the TomTom app - dismissed it, because the speed information was 88% inaccurate and the app layout/CarPlay experience was not very satisfying me.
I used HERE WeGo, most time on my last trip, it's okay, but there are a few drawbacks, when I plan the next day route on my browser, it will not synchronize to the app. Importing GPX is having issues and not usable. So, I mostly just checked the destination point and added it as a favourite to easily find it for navigation on the mobile. (BTW - this is the same procedure, I use on MRA).
Apple and Google Maps - well it is cumbersome to download the maps on both for offline navigation (just in case).

As I am not a biker (anymore) just using my car with an attached tiny-camper trailer, most I need is just a pure navigation that will lead me where I want to go.

However, when using MRA next, sometimes it's not reliable - my wife for example used MRA to get to a parking with transfer to the airport. She used it a few times and all time the system routed her differently using the same settings. Only one time it used the best and fastest and most uncomplicated route. The other times it took routes through rural and city areas, whereas there is a very close by highway exit and you just need to take two turns and you are at the parking. I mean a navigation system should be optimized for such a route. As said no changes of any setting. Not to mention, that such a navigation sometimes is time sensitive and critical. And when you end up in 30 km/h zones etc. you start to shiver and scold.

@Cookie-On-Tour To be able to navigate accurately, on the roads that you want to use, you first have to route plan accurately. Your example above does highlight a strange phenomenon in the HERE map, but by positioning an extra route point you can make the HERE map follow the same route as TT and OSM.
It is the same for your wife travelling to the airport, with route points positioned on the roads that you want to use, the same route will be used each time you travel on it.

@Nick-Carthew I agree, but as said most of the time for any pure navigation software or device, when it is used as ad-hoc navigation - not being in the position to plan the route, the outcome should be more consistent and reliable.
While planning, sure I can add waypoints, however, this only makes sense if you know the area and the best route. Shouldn't a smart navigation system do this for you?

I fully agree!
Just for A to B MRA is acting strange:
The last time I used it directed me over the Schiphol airport roads thrue the arrivals and then back to the same highway... WTF??

People call that sightseeing

Well the TomTom was not better as I tested it

[Brian McG]

these navigation devices are nothing but statistical engines, for the same input parameters will give give the same output, there is no chaos theory involved in how they calculate routes
if you are getting different outputs then there must be a different input,
this could be something like traffic because we all know we want consistent routes but also want to avoid traffic which blows your consistency out of the water
or it could just be something as simple as the time of day, one route might be faster at 9am than another route at 9:05

[BertM]

@Brian-McG
It is not a different input when going from A to B, it is just one simple thing:
I am at point A and want to point B.
If the program routes me off the Highway and put me back on the same Highway at the same junction that cannot be the fasted route.

[Con Hennekens]

@BertM, actually, depending on the routing engine, in the Netherlands it can

Since in the Netherlands max speed on highways is 130kph but during daytime limited to 100 with signs, it can happen that on highway entrances the 100 sign is somewhere in the distance, making it lawful from the entrance to the first 100 sign the max speed is 130 during daytime. Not all highway entrances immediately have a 100kph sign, making the detour faster than staying in the highway (in theory).
