Re: [sumo-user] Reading large SUMO output files
Hello,
you can use the tool traceExporter.py to filter sumo fcd-output on the fly and put the output into one or more target files (for each target file a bounding box, and time range can be configured). It is also possible to change the sampling interval and the percentage of vehicles that shall be exported.

Read here about connecting sumo and traceExporter directly via a socket so that no large file must be written:

Read here about filtering: http://sumo.dlr.de/wiki/Tools/TraceExporter#fcd

Unfortunately, there is currently no tool to perform the same type of processing for the netstate-dump.
regards,
Jakob

Hello team,


I ran a simulation for an area with below mentioned configurations. Total number of vehicles generated in trip.xml file were 145436 for 1 hour. Simulation took approximately 3-4 hours to complete. Now due to size of the output file (fcd and netstate dump), I am not able to analyse it. Can you please suggest any tool or python script which I can use to break the output files based on given timestamp, say output file for every 10 or 15 minutes?


Also, will it be a good idea to run simulation for longer duration, for e.g. 30 days with below network file or we should take smaller area. Please suggest.


Input Configuration: 

  1. Net file: 61 MB ; total route length: 3132 km ; No. of edges: 29332
  2. Trip File: 21 MB

Output Configuration:

  1. Fcd Output: 27 GB
  2. netstate-dump: 15 GB
  3. tripinfo-output: 11 MB

Thank you again for your quick suggestions.
