1) marouter is capable of generating route alternatives. The option --paths.penalty can be used to enforce creation of alternatives by penalizing already found routes and then routing again. 2) No. Though I expect this might work. What we already did is run instances of the mesoscopic simulation a few minutes into the future to predict traffic states (and then roll back to an earlier state.
