AFAIK, the stop command tells a vehicle to stop in a given lane for a defined period, then it resumes its path. http://sumo.dlr.de/wiki/TraCI/Change_Vehicle_State#Command_0xc4:_Change_Vehicle_State
The speed command forces the vehicle to keep the given speed. I don't know if this would lead to collisions. There's another relevant command, "max speed", that you can use to limit the vehicle to a certain speed, changing lane and slowing down if necessary. TraCI4J currently supports only the max speed command. If you want a vehicle to stop, you may set the max speed to zero using Vehicle.queryChangeMaxSpeed(). The two commands above are not (yet) supported in TraCI4J.
