pedestrians jump on walkingareas

[Domsall]

I created a subsecond marketplace scenario with many junctions and sidewalks for pedestrians. During simulation I recognized that pedestrians get "pushed back" when they switch from one WalkingArea-Lane to the next.
It seems for me that these lanes do not have a kind of continuous expression (see below), but rather "hard" discrete changes.

I attached an example and pictures of the problem (happens at 9.7s/9.75s): ped_push_back.zip

What I think is happening:

Yes. I think your last image describes the situation perfectly. The same issue shows up within a single lane where it is curved. Fixing this is beyond the scope of the striping model. Even with a complete new pedestrian model you would have to recompute the geometry internally to account for the coarseness of the current network model.

I never recognized that this is network-specific and also applies to all other vehicles, probably because vehicles and even bicycles are a lot faster and "jump over" such corners.

WalkingAreas are created automatically, so I would probably try to smooth the shape (beginning and ending), just like I would do with roads/lanes.

Would this add issues to the striping model?

[namdre]

As discussed yesterday, the smoothing would have to happen inside the striping model which computes the path over a given walkingarea.

jup, that is the "follow up" issue with the concrete problem/request
