| Re: [sumo-user] Evolutionary Algorithm to remove jams (like MATSim) |
Interesting. Thank
you Jakob and Ilya for your comments. @Ilya:
I don’t use public transport, but I do use parking areas. Will
let you know if I have any progress.
It seems that I have two options to systematically improve the traffic flow:
duaiterate.py
and implement some basic evolutionary algorithm. I'm thinking of the
2nd one, but not sure how to convert the demand data between the
two programs. I'll do some research - thanks again for your help
:-).

There is currently no tool in sumo that would systematically adjust departure times to improve traffic flow.

However, I've got some problems using parking flows and public transit, unfortunately, I haven't fixed it.The second annoying thing is amount of output files you will have and instead of MATSim you will have just one folder for all iterations.If you will successfully use duaiterate it will be great to see how to fix file-chaos and problem with pt and parking.

Hi everyone. MATSim (another agent-based simulator like SUMO) makes use
of an Evolutionary Algorithm to optimise the demand to prevent
unrealistic traffic jams.
The software runs the simulation multiple times, and in each iteration,
it slightly adjusts the times and routes of the trips, gradually
eliminating traffic jams. Is there anything like this planned or
implemented in SUMO?
The reason I am asking this question: I am using a statistics file to
describe the city, then use ActivityGen and DuaRouter to convert the
statistic file into demand that can be imported to SUMO. However, there
are jams because the vehicles follow the statistics file too precisely.
