Re: [sumo-user] pedestrian teleporting to opposite side at junctions

[Jakob Erdmann <namdre.sumo@xxxxxxxxx>]

This explains it: You need to select the edges to be crossed, rather than the edges connected by the crossing. Note, that this allows you to define middle islands by creating two consecutive crossings on the same side.

Make sure that the edges being crossed have at least some lanes that prohibit pedestrians.

This is the bigger intersection:

Here the crossing is marked invalid (red) because the lanes being crossed permit pedestrians.

Can you show a screenshot that shows which edges you marked 'green' to create the crossing?

I didn't move it manually, actually, I don't know how I can move it. I just selected the intersection and then the two edges on the western side and created the crossing. Here is another example, from a simpler intersection. I thought it might be because of the edge spreadType, but it is set to center on this one.

The crossing you defined is attached via the thin grey wedges to a walkingareas outside the viewport (possibly because you moved it there manually?). To get a crossing on the western side of the intersection, it needs to be defined as crossing the western edges (road and tram).

Thanks. adding crossings solved the issue. Just wondering if the location of the crossings could be manipulated or changed in a way to be placed on top of the connection line. There is a slight offset between the actual crossing and the zebra cross markings

What you are seeing is the "fallback" behavior of pedestrians when the network doesn't have the required infrastructure.

Walkingareas are added automatically once you define at least one crossing in your network (https://sumo.dlr.de/docs/Netedit/editModesNetwork.html#crossings)

Most likely, you'll want some automation though: https://sumo.dlr.de/docs/Simulation/Pedestrians.html#building_a_network_for_pedestrian_simulation

Dear all,

I am modelling a multimodal network including pedestrians and I observe a strange behavior in one direction for pedestrians: they are all teleported to the opposite side of the road once they reach the traffic light (shown by the red arrow). I am not sure how to define walking areas and crossings in NETEDIT to avoid such behavior, but I was also under the impression that connections work similarly to vehicles. Is this expected because pedestrians are free to move inside the junction?

P.S. The network is partially from OSM. I have added the sidewalks manually in NETEDIT together with the connections at the intersections. 

Thanks,

Sasan
