I found another problem with the model. Please check out [19356]. Ooh. Look at those quiet cars just sitting at the stop light. Well done!

It was related to sub-second simulation (http://sumo.dlr.de/trac.wsgi/ticket/1440). Thanks for supplying the scenario. Hmm. Just did an svn update to 19353 and rebuilt. The issue seems to still be present, but at a very much smaller rate. The northbound vehicle labeled f0.1 which appears at the intersection at around time 58 stays quiet until around time 76, where it jumps once before the light changes to green at around time 91. I’m still using a step length of 0.1 seconds. - Tom The connection issue is a caused by a known design problem in the heuristic for lane guessing which I hope to fix soon. Also, explicit connections are currently not imported from OSM (http://sumo.dlr.de/trac.wsgi/ticket/1990) so you currently have no option for specifying them in your OSM input. The preferred work-around would be to either a) specify additional .con.xml files when doing the OSM import (http://sumo.dlr.de/wiki/Networks/Building_Networks_from_own_XML-descriptions#Explicitly_setting_which_Edge_.2F_Lane_is_connected_to_which) b) specify your network in sumo plain-xml files (http://sumo.dlr.de/wiki/Networks/Building_Networks_from_own_XML-descriptions) c) design it with NETEDIT.

I updated using: svn update make -f Makefile.cvs make Here is my test case, with a six-lane intersection generated from a hand-built OSM file. The README has the commands I used to generate the derived files and run the test case. Hopefully I got those about right. Note that the east-west road has only a single lane of through traffic, so the jumping behavior is limited to the north-south road which has three lanes of through traffic. (I would like to convince netconvert to have both roads with three lanes of through traffic; suggestions appreciated ;) Look for a northbound vehicle jumping between the left two lanes at about time 60.
