Handling of the Via Points

[afischerdev]

A while ago we introduced the correction of the via points #494 (misplaced via points). This produce something like this situation:

BRouter clients can use the segment by segment calculation (blue path) or an all in one calculation with the chance to remove unexpected way parts (red path). The all in one method has its problem in the recalculation, all is done again. While segment routing only ask for the parts before and after the moved via point.

What if the BRouter library returns the replaced via points. All clients have the chance now to do the recalculation from the corrected point and merge the parts there.

What do you think?

Please keep in mind, the misplace logic is not complete now. #519 is not done now for the roundabouts.

What BRouter returns now? Doesn't it return the corrected via points in the turn instructions?

This method will again work when we do all in one calculation and not in segment by segment calculation?

What BRouter returns now?

Nothing but the route. We have the option exportWaypoints=1 that brings the waypoints into the export and there could be an option exportCorrectedWaypoints=1 for example.

Doesn't it return the corrected via points in the turn instructions?

No, At this via point it would be a turn instruction straight and that is removed.
Only the timode=2 (Locus) has a marker:

<trkpt lon="13.196587" lat="52.467697"><ele>40.75</ele><sym>pass_place</sym><type>Via</type></trkpt>
