Description of the bug In the case of a simple geometry with a channel inserted in between two bigger rooms, the pedestrian gets stucked into one corner before entering the channel.

Expected behavior The channel has a width of 3m, so the pedestrian should be able to enter and walks his/her way out of the channel.

Additional context Here is the geometry and the trajectory which can be visualized with this script.

To which points does the goal of the agent point to?

[bcoueraud87]

The agent should finish its journey at the end of the room right after the channel. Concretly, in the coordinate system that we use, it is the point (299.9, 0).

After looking into this I can see that the navigation graph is not constructed correctly.

In the picture below you see the portal edges (edges between the to-be-traversed triangles). The image contains the following errors:

• A boundary edge is selected as portal edge, this is incorrect because a portal edge has to be an edge shared between to adjacent triangels
• A portal edge that should have been selected is not selected
• A portal edge is selected twice (notice the different draw pattern of the green line of the center portal)

Im inclined to first make all these internals accessible from python to ease future debugging although I do not want this to become part of the public api.

@bcoueraud87 this should be fixed on SUMO-Integration, can you please verify.

@Ozaq I confirm that the problem has been solved, thank you. I propose to close this ticket.
