Hello, I understand that there are legitimate stop positions which are currently covered by intersections. The vehicle dynamics certainly allow stopping there but I cannot tell you whether it will ever be allowed before pondering all the implications on the current implementation. The constraints for positioning busStops and regular stops are now more precisely defined at http://sumo.dlr.de/wiki/Definition_of_Vehicles,_Vehicle_Types,_and_Routes#Stops and http://sumo.dlr.de/wiki/Simulation/Public_Transport Besides repositioning you could try to other things: - modify the shape of the junction, or - (if you do not need turnarounds at that location) split that junction into two junction, one for the east-west direction and one for the west-east direction (which will be a lot smaller then) regards, Jakob
