| Re: [sumo-user] Issues with Traci Python Script |
Hi Ifezue,
this is more a python than a SUMO question, you can use in python3 something like
f = open('test.csv,'w')
...
print('%d,%d' % (step, count), file=f)
...
f.close()
Regards,
Harald
Also, how exactly can you get the data printed on the command line into a csv file or a format that can allow for data analysis to be performed?

Thank you Harald. That seemed to have fixed the problem.
I did have another question. Is it possible to print the traci.vehicle.getPersonNumber() output into a plot through the matplotlib module in Python?

_______________________________________________Hi Vincent,
thanks for providing the test data.
Your simulation does as told by the python script.
You should start the second loop with
while step >= 3600
(instead of while step > 3600)
At the end of the first loop step has exactly the value 3600.
In your testdata are two errors:
1) the additional files osm.poly.xml and osm.view.xml are missing
2) when I omit these files from test.sumocfg, the command "sumo -c test.sumocfg"
gives these errors at the end
Error: The lane -gneE253.50_1 to use within the busStop 'O5' is not known.
Error: Could not end a stopping place that is not opened.
Quitting (on error).
and about 20 warnings
Greetings, Harald

Hello Everyone
I just started using Traci so the nuances of using it are new and a little weird to me. Right know I am trying to have python run my simulation and also collect or print information out about the number persons that use a bus vehicle within my simulation. However, for some reason when I run my Python code, the simulation runs but closes at a certain specified time which is what I don’t want Traci to do.
For example right now, I have my Python code setup so that it from simulation step of 0 to 3600 it is allowed to advance the simulation step as normal, but after 3600, I want the simulation to begin collecting person ids or number of persons on buses within my simulation. It is after the 3600 simulation step that the simulation decides to quit rather than just continuing on and counting the number of persons entering the buses.
For reference, I have attached all pertinent file information to this email provide some insight into what I am referring to.
Thank you in advance
Ifezue
