Proposal for an algorithm to guide around unexpected road closures
-
In a thread "https://forum.myrouteapp.com/topic/10748/how-to-exclude-short-time-road-blocks-during-navigation/1", there was an intense discussion about the pros and cons of guided detours around unexpected road closures. Some motorcyclists prefer a solution similar to TomTom.
I would like to propose an algorithm that, in my opinion, would enable guided detours around road closures.
The scenario: A motorcyclist is navigating with MRA on a pre-planned route. He encounters a temporary road closure that is not marked on the planning map and is therefore not bypassed.
The task is to create a feature in MRA that guides the rider around the closure, similar to TomTom.
Definitions:
Shaping Point A: the point where the motorcyclist is actually located before the roadblock.
Shaping Point B: the point on the known planned route beyond which a roadblock is suspected.The algorithm could work as follows.
1: The rider stops and selects “Detour around a roadblock” from the navigation menu. There, he enters the length of the expected roadblock (e.g., 10 km).
.
.
2: MRA now automatically adds the two additional shaping points, A and B, to the route. The waypoints along the remainder of the route after Point A to the destination are incremented by 2, since the route now has two more shaping points.
.
.
3: MRA excludes the section between shaping points A and B from the permitted roads—similar to how it handles highways or toll roads to be avoided, etc. To do this, a programming solution must be found that does not rely on the planning map, since this exclusion is not present there.
.
.
4a If a planned shaping point is located on the now-blocked route, it is skipped.
4b: If a planned viapoint is located on the now-blocked route, a warning is issued so that the rider can decide whether to be redirected to that point from B or to skip it.
.
.
5: MRA now calculates a new route segment that leads at least to point B. If the original route is not reached again until further along toward the final destination due to road conditions, shaping point B is skipped during navigation.Of course, I don’t know how this can be implemented programmatically, but that’s what @corjan-meijerink, our mastermind, is here for.

All this would be possible without all the hassle of adding extra waypoints
That said it’s not a currently planned feature but it is in my mind after reading the interesting discussions. Quite often those suddenly magically get done (or at least a proof of concept) over a boring weekend

Not making any promises!OK, thanks for your response.
I just wanted to document an idea I got during a walk with my dog.

@Axel-Härtl that is definitely appreciated!

@Axel-Härtl I read the discussion carefully and I completely agree with your proposal. Anything that improves MRa is welcome!
