Hi,

I am trying to model the evacuation of pedestrians in a city using the Continuous Move evacuation model.

However, when I use my buildings shapefile (that I have joined to this message), not all people agents are able to arrive to the evacuation target.

They are mainly getting stuck in narrow passages between buildings, or in the hollow parts of the building when it has a concave shape.

Did anyone face this problem? And do you have any solution to make the people move around the obstacles?

Any help will be much appreciated.

Regards,

Rouba

Dear Rouba,

Indeed, with this model, it is possible to have agents stuck. There are two solutions: using a grid (on which you can compute a path - there is an example in the library) or using the pedestrian skill of GAMA. Concerning the pedestrian skill, you have to install the pedestrian plug-in (on the experimental website). However, the development of the plugin is still ongoing, so for the moment, the documentation is pretty poor.

Cheers,

Patrick
