Hello, The issue you describe is a common occurence with OSM-derived networks. What netconvert options did you use? There are a number of options that may be set to improve the OSM data heuristically. Take a look at http://sumo.dlr.de/wiki/Networks/Import/OpenStreetMap#Recommended_NETCONVERT_Options http://sumo.dlr.de/wiki/Simulation/Traffic_Lights#Improving_Generated_programs_with_knowledge_about_traffic_demand A core issue with OSM networks are complex intersections. A number of improvements have gone into the latest development version of netconvert in regard to importing these intersections. You can already try it out at http://sumo.dlr.de/wiki/Downloads#SUMO_-_Latest_Development_Version
