BRouter (offline) routing in Villages/Cities

[micclass62]

Hello,

recently came back from a 2000km+ Motorbike tour through Switzerland and the French Alps. Was using Cruiser (4.0.2) with BRouter (offline) for the routing.

Coming from Kurviger2 (which was the optimal solutions for myself) Cruiser is working well too. Nothing to complain about navigation at all. Rerouting (due to blocked roads) worked even better now with offline BRouter (in the past this was often not working due to missing mobile connection in rural areas).

The only issue I do have: For the routing I do use a "Curvy" profile with:

Autobahnen: 4/5, Fernstrassen: 3/5, Hauptstrassen 2/5, Sekundärstrassen: Aus, Tertiätstrassen: Aus, Nicht klassifizierte Strassen: 3/5, Wohnstrassen: 4/5

Outside of Cities and Villages this leads to routes that fit my expectations quite well. Only in very rare cases that are small "deviations" away from the road I am on coming back a few hundert meters later. Typically I can see such a situation and avoid it.

Unfortunately inside villages and cities I do get a lot of routing through very small roads (even sometimes through courtyards) and housing areas. This is not what I do want.
For the - rare - cases that I do pass through larger cities (I try to avoid doing that) I can manually handle the situation by adding shapingpoints in front and after the city and change the profile to fastest in between (thanks for that feature!). But for the smaller villages this would be way to much work to be handled manually.

Question: Is there a way to avoid going through very small road inside villages (and cities) automatically? Outside I still want to use the curvy profile, but inside I would want to switch to fastest. Any chance to get such a behaviour?

Cheers,

Michael

Hi @micclass62 thanks for the kind words!

It's a little complicated to do it automatically without compromises.
(especially for all kind of populated areas, like villages)

If want a specific route profile (e.g. fastest) in a specific area,
better to set 2 waypoints before and after the area and set the route profile for that route section.

To avoid specific areas we are working on a new feature to freely define no-go areas in route planning:

• Use no-go areas in route planning #538

The first implementation is already available for testing:

• Cruiser 4.1.0 (Beta) #544

@Leeb64

4/5 is 5, 5/5 is 1, so can use 5/5 or extra curvy route.

[Leeb64]

That's right. Off is 0!
I thought 4/5 would be 1...and 5/5 would be 0.
Then 5/5 should be reduced to ~ 0.2.

[devemux86]

0 is absolute avoid and can lead to failed routing and users not understanding the reason, so it's better to avoid it.

[Leeb64]

Normally, when “Avoid Cities” is activated, things like driving on small streets like this shouldn’t happen.
But you could also reduce the "Avoid Urban/Residential Streets" factor to below "1" at 5/5.
I just ran a few quick tests and I think 0.5 is still OK.(Especially at “avoid urban factor”)
Increasing the speed also helps

[devemux86]

I think that BRouter's avoid cities currently work with minimum population 50 k people,
so we need much less population to be really useful.

Anyway, these tags sometimes work or not, so better to use the common avoid road types and no-go areas.

Their documentation is here.

consider Town:OFF

consider Town:ON
No city with more than 50,000 inhabitants nearby

@Leeb64
Could you please help me? What URL and what vehicle did you use to get the above screens?
I tried to get such selection of options and failed:

You see, I took "Treckingrad" - Auto and Moped didn't show a similar collection ...
Thank you in advance!

Ausgangsprofil ist driving-cruiser:
driving-cruser.brf.txt

Ich habe mir 2 Profile erstellt.
Landstraße 2+3 .brf.txt
Landstraße 3+4 .brf .txt
(Das "txt" löschen.Braucht man nur zum Hochladen hier.)
Das erste bevorzugt Strassen 2. + 3. "Kategorie",das zweite Strassen 3. + 4. "Kategorie"
Beide versuchen Ortschaften+Städte zu umfahren falls möglich-es werden zum Teil auch mautfreie Autobahnen dafür benutzt.

Umfahren von Oyonnax(2+3Kat).
Aufrufen kann man diese externen Profile so: Menue(3Striche links unten)/Routing/Optionen/Erweitert/BRouter Profil/Externes Profil öffnen-> externes Profil Laden.
(An den externen Profilen kann im Cruiser nichts mehr eingestellt werden.Allerdings könne sie mit einem Texteditor auf dem Smartphone verändert werden.Nach dem Ändern Cruiser ab und anschalten.)
Am besten im Menue 2 neue Routing Profile erstellen-

Diese BRouter-Profile lassen sich mit dem BRouter WebClient testen und verändern. Kleinere Werte bedeuten eine höhere Vermeidung
Damit lassen sich diese externen Profile leicht laden:
https://brouter.de/essbee/#map=7/48.9973/7.8259/OpenTopoMap
(Profiles/ein lokal gespeichertes Profil hochladen und aktivieren)

Danke @Leeb64 !
Werde jetzt mal ein wenig damit "spielen" (und es mit Kurviger vergleichen).

[Leeb64]

Vorsicht!
Es gibt verschiedene Versionen des BRouter WebClient! Leider!Jeder benutzt da eine andere(ältere)BRouter Version.
Die Version die ziemlich das gleiche abliefert wie die im Cruiser implementierte->:https://brouter.de/brouter-web/#map=6/48.8207/7.4377/OpenTopoMap
Diese Version ist nicht so komfortabel was das Einfügen der eigenen Profile angeht.
Man muss das Profil im WebClient löschen und das eigene einfügen.

The different BRouter website versions are mentioned here:

Unless playing with the new environmental options, the routes should be similar.
