Thanks Jakob,
I can now visualize and automate the simulations.
sumoProcess = subprocess.Popen([sumoBinary, "-c", "simexp.sumo.cfg",
"-r", "randomroute.rou.xml",
"--remote-port", str(now_port), "-S", "true", "-Q", "true",
"--emission-output", "12marEMS.xml",
"--tripinfo-output", "12marTIPop.xml"], stdout=sys.stdout,
stderr=sys.stderr)
Next, I want to save the output of all the 10 simulations separately at
a particular destination without over-writing the same file, i.e; with
different names which can from seed value. I am not sure if options will
provide that flexibility.
I am thinking of copying the output file to a particular location.
http://stackoverflow.com/questions/123198/how-do-i-copy-a-file-in-python
Is there a more efficient way to do this?
