| Re: [sumo-user] weight update inteval |
Thanks. I have another question. In the case of having flows as our assignment method, do we need to set device.rerouting.probability, in order to make vehicles reroute in the case of jam, or rerouting happens automatically?On Sun, Jun 7, 2020 at 3:19 AM Jakob Erdmann <namdre.sumo@xxxxxxxxx> wrote:Yes. If device.rerouting.adaptation-interval is small, then CHRouter will spend more time updating itself and this will slow down the simulation._______________________________________________Am Sa., 6.

Also, as a consequence, the real-time factor will be smaller (simulation time doesn't change that much, as I noticed)?On Wed, Jun 3, 2020 at 2:05 AM Jakob Erdmann <namdre.sumo@xxxxxxxxx> wrote:At the given interval, the weights are updated and those are used automatically by Astar and Dijkstra.

You can visualize the current weights in SUMO-GUI (color by edges "by routing device assumed speed") and you can also save the values to xml using option --device.rerouting.output FILE_______________________________________________Am Sa., 16.
