After scouring the docs the whole day, the only solution I can think of
is to use getShortestPath() from sumolib.net.Net
<https://sumo.dlr.de/daily/pydoc/sumolib.net.html#Net>, and build
arou.xmlfile from its outputs. Does that sound possible? I was hoping
for an easier way. Also I wanted to double check that the function is
maintained before I start coding.

Hello all,
I currently have around 2000 trip files, each describing the trip
that a vehicle makes via a series of stops, as follows:
<trip id="Taxi1_Day1" type="eTaxi" depart="53564" from="173819953"
to="802374502#1">
<stop lane="173819953_0" until="53565"/>
<stop lane="68612608#0_0" until="53650"/>
⋮
</trip>
Each trip file has around 750 stops. My aim is to generate a
simulation corresponding to each trip file, which routes between the
stops of that trip file. All the trip files correspond to the same
network file, which is around 480 MB big. I want to do the route
generation from Python preferably.
My current approach is to run duaIterate.main()
(from$SUMO_TOOLS/assign) for each of the trips. However, this is
taking very long. I think the problem is thatduaIterate.main() takes
a lot of time to load the network each time. It also takes almost all
of my RAM to load the network, so I can't run the process for
multiple trip files concurrently. It would be great
ifduaIterate.main() provided a way to pass in the network /object/
(i.e. sumolib.net.Net), rather than the /path/ to the network file.
If I could do that, I think it would take much quicker, and I could
run multiple duaIterate processes concurrently, without running out
of ram. Do you know if it is possible, or if there is a better
approach?
Regards,
Chris
