Hello, - the same thing that were said about changeTarget also apply to findRoute. Note, that findRoute also accepts the routingMode command. - duaIterate.py can take between 10 and several hundreds of iterations to converge. Unfortunately it is hard to tell in advance. One known problem occurs when the initial simulations are so congested that no good information is generated for the subsequent run. You could use marouter to get a better starting solution and cut down the number of iterations.
