Hi Jakob, Thank you for your reply. As the default routing algorithm in one-shot.py is astar, this is the routing which is responsible for finding the best route. The total number of edges is 108k. Using sumo as cmd was a good idea, thanks for this. So, I used DUAROUTER and generated the routes for the same set of trips that I fed into oneshot, with this configuration: <files> <net-file value="map10_limitedWellington.net.xml"/> <route-files value="Routev1800000in30min_v1trips.rou.xml"/> -> used DUAROUTER for this </files> <process> <begin value="0"/> <route-steps value="200"/> <routing-algorithm value="astar"/> <device.rerouting.probability value="1"/> <device.rerouting.period value="300"/> FOR ASSIGNING NEW ROUTES TO VEHICLES <device.rerouting.adaptation-interval value="1"/> <device.rerouting.with-taz value="False"/> <device.rerouting.explicit value=""/> <vehroute-output.last-route value="False"/> <vehroute-output.exit-times value="False"/> <vehroute-output.sorted value="False"/> </process> <reports> <verbose value="True"/> <no-warnings value="True"/> </reports></configuration>
Generally, this is much faster than one-shot as only after 20-30 min the simulation step is about 7000 ( although I am aware that I am only doing the routing in 5 min intervals and am missing the routing at the departure time as one-shot does these rerouting at these two step (departure and predefined intervals)) ~/Desktop/sumofromgit/bin$ sudo sumo -c TestBigdata.sumocfgLoading configuration... done.Loading net-file from 'map10_limitedWellington.net.xml'... done (4512ms).Loading done.Simulation started with time: 0.00Step #6986.00 (1186ms ~= 0.84*RT, ~46293.42UPS, vehicles TOT 65099 ACT 54895 B while after 3 days of running one-shot, one-shot.log shows step 1036 as the last line of the log: Step #1035.00 (371223ms ~= 0.00*RT, ~21.80UPS, vehicles TOT 8135 ACT 8094 BUF Step #1036.00 (369297ms ~= 0.00*RT, ~22.00UPS, vehicles TOT 8167 ACT 8126 BU By the way, I was not aware that we can post our questions to stackoverflow, so I post another version of my question there :https://stackoverflow.com/questions/52085610/how-to-allocate-more-cpu-and-ram-to-sumo-simulation-of-urban-mobility In between, which is a better place to ask questions: stackoverflow or here?

You can test this by simply starting sumo with a fraction of the trips and option --verbose. You will get some output on the command line that tells you how much time the routing took and how many network edges were check while computing the route.You can speed up routing by selecting another routing algorithm (http://sumo.sourceforge.net/userdoc/Simulation/Routing.html#Routing_Algorithms)Possibly, the simulation does not continue due to heavy jamming. This is best investigated by looking at the simulation with sumo-gui (see http://sumo.sourceforge.net/userdoc/FAQ.html#The_simulation_has_lots_of_jams.2Fdeadlocks._What_can_I_do.3F) regards,Jakob 2018-08-28 20:55 GMT+02:00 mohsen hs <[email protected]>: Hello there, I am running one-shot.py for 140k trips in(uniformly distrusted in the first 30 min of simulation) min and it seems very slow.

Looking forward to hearing from you.
