problem with agents moving on graph roads from shapefile

[lyuba mancheva]

Hello to all!

I have a problem with agents implemented to move on a graph of roads, created from a shape file. My problem is that the agents don't move on that graph while the expected behavior is to move. I have tested the code with 3 different roads shapefiles exported with QGIS.
I have tested the same code with shape files provided from GAMA examples and it's working.
I have added here a zip file with an example of the my code and the shapefile that I am using. Maybe there is a specific procedure for exporting/creating/implementing roads shapefiles?
Thank you very much in advance

hi, 

I'm not sure of my answer but I think the problem comes from your shapefile.  Your example works with related graphs such as the first two graphs in your model. However, the last shapefile (in your model) gives a graph with 62 components. Therefore, it becomes impossible to calculate a path from a point a to a point b if they are not on the same related subgraph.

Hello thanks;
ok, it is possible as a solution.
I don't know how to process a row shape file of roads to be considered as one related graph so agents can calculate path on it.
Thanks

Don't know if it would work for your case, but the gama function `clean_network` can connect disconnected edges to create a continuous graph. Searching on the forum should bring some examples.

Thanks
