If those speeds are wrong maybe you need to use another typemap when importing (there are different defaults for some road speeds in http://sumo.dlr.de/trac.wsgi/browser/trunk/sumo/data/typemap). You can also make vehicles change their behavior relative to the speed limit by setting attributes speedFactor and speedDev in their vType > > 3) generateTripsXml.py + duarouter --- How i get district and matrix file > for an osm map which is required for generating trip file from > generateTripsXml.py . > generateTripsXML.py is obsolete. Use the od2trips application for building trips from od-matrix files. You may get the required input files from the city authorities.
