Hi,
for my simulation I have written a small script, which plots the number
of passenges per car over the time base on the fcd data supplied by SUMO.
Attached is a sample output

@ Harald: Thanks for providing this information. I will try to
implement this within my code.
@ Jakob: I tried out what you suggested, but this output gives me a
lump sum. This is informative, but I was trying to see if I could get
output from SUMO that contains the number of persons riding a bus over
a continuous time period, similar to what you see in a time series
plot where you can see the number of passengers relative to a
timescale (e.g. second, minute, or hour).

The statistical summary from the command line output can also be
obtained in xml with option --statistic-output.
xml can either be loaded directly in Excel or convertd with
sumo/tools/xml/xml2csv.py

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
