[sumo-user] multi-path algorithm and prediction in sumo

["Hoffmann, Pascal" <pascal.hoffmann@xxxxxx>]

Dear sumo users,

 

I’ve got a question concerning the topic of traffic assignment in sumo. I want to build and test an a-star routing algorithm with sumo, which is able to randomly assign vehicles on a set of alternative routes in case of congestion or any other travel time delay.

1. Therefore, I want to ask you, whether there is already any multipath algorithm (...-dijkstra or a-star) for alternative routes implemented in sumo? So far, I did not find anything in the mailing lists and on stackoverflow.
2. Furthermore, I want to ask you, whether anyone already tried to use the macrosimulation for a “prediction” of the traffic in a next time step? My target would be to get the densities of the edges in a next time step like 1 minute ahead. So that the routing algorithm could assign the traffic, in case of congestion or rising travel time.

Best Regards,

Pascal Hoffmann
