Dear Pietro, yes, using the latest version of sumo and your network in the new format i still see collisions. Using the default seed i get 3 and using different seeds i get between 2-5. These collisions are indicative of some kind of bug and I'm looking into that right now. regards, Jakob 2011/11/16 Pietro Niccoli <pi...@ti...> > Dear Jacob,**** > > I downloaded the last svn version of sumo and the wrong collisions have > now disappeared, but some **** > > collisions (4) still happen.
