Re: [sumo-user] FCD Output
Sorry for asking.
I have several traffic flow definitions, fn1, fn2,
I only need to export the FCD data for the vehicles that are generated
under specific flow definitions, say fn1. Is this possible?
Regards

[sumo-user] FCD Output
Good Morning,
There might be many answers regarding this query, but sorry for asking
again.
I wanted to get FCD out of *time, id, speed, pos, and lane* only, and for
that, I gave the following command.
*traci.start([sumoBinary, "-c", "data/intersection.sumocfg",
"--fcd-output.attributes time,id,speed,pos,lane", "file.xml"])*
I am getting the following error:
C:\Program Files (x86)\Eclipse\Sumo\tools\traci\main.py:159: UserWarning:
Could not connect to TraCI server using port 55103 (TraCI server already
finished). Retrying with different port.
warnings.warn(("Could not connect to TraCI server using port %s (%s)." +
Traceback (most recent call last):
File "runner.py", line 89, in
traci.start([sumoBinary, "-c", "data/intersection.sumocfg",
File "C:\Program Files (x86)\Eclipse\Sumo\tools\traci\main.py", line 162,
in start
raise FatalTraCIError("Could not connect.")
traci.exceptions.FatalTraCIError: Could not connect.
Am I doing something wrong? I am not sure if I specify it correctly.
Regards
Radha
