Hi Albert,

Thank you for your advice.

Sorry but I am new to this simulator. :)

Best regards,

Hi Antonio,

Why not try the interactive tool? Use the Python script ../SUMO/tools/osmWebWizard.py. Search for a place, use Select to specify the area (drag sides), then generate a scenario.

Did you try selecting a smaller area to see if that works? I think the network for all of Berlin must be quite large so you are running out of RAM.

Dear Community,

Iam trying tto download the osm map of  Berlin city as explained in http://sumo.sourceforge.net/userdoc/Networks/Import/OpenStreetMapDownload.html (section Downloading a city).

However, I constantly receive an xml file which contains the same message listed below:

<?xml version="1.0" encoding="UTF-8"?>
<osm version="0.6" generator="Overpass API 0.7.55.7 8b86ff77">
<note>The data included in this document is from www.openstreetmap.org. The data is made available under ODbL.</note>
<meta osm_base="2019-12-09T18:07:02Z" areas="2019-12-09T17:31:02Z"/>

<remark> runtime error: Query ran out of memory in "area-query" at line 4. It would need at least 2 MB of RAM to continue. </remark>

</osm>

I checked on internet but I didn't find anything related to this issue. Moreover, I obtain this message only for some cities, Berlin include.

I would really appreciate you help and suggestions.

Best regards,

Antonino
