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
