Re: [sumo-user] Issue trying to create route file using randomtrips and

[Hrishikesh Barad <hrb1731@xxxxxxx>]

Hi Harald, thanks a lot for the detailed response.

 Can you elaborate what do you mean by 'duarouter is called from randomTrips with --ignore-errors'? What do I need to add to my code to call duarouter within randomtrips loop?

Thanks again,

Hi,

here are some ideas:

1) might be the routes_abc.xml file is locked by the sumo-gui and is not overwritten (duarouter is called from randomTrips with --ignore-errors)

2) Have you tried your loop without the sumo_gui and checked that there are new route_files?

3) you can use in each loop a new route file name.

4) does the sumo-gui processes terminate?

5) Have you tried absolute filenames?

6) Some parameter (period, seed) in your call to randomTrips are given as int not strings

Regards, Harald

Hi friends,

As shown below in the code, I am trying to create a route file ('route_abc.xml') using .net file ('simexp.net.xml') and an additional file ('vdis100.add.xml') and then use the generated 'route_abc.xml' to run the SUMO simulation. And before running every simulation I just change the additional files (I have them already prepared in a folder and they are named vdis10, vdis20 and so on) 

#CODE START---------------

randomTrips.main(randomTrips.get_options([
            '--net-file', 'simexp.net.xml',
            '--min-distance', '1500',
            '--period', 4,
            '--binomial', '1',         #uniform arrival
            '--seed', 8123,
            '--trip-attributes', 'type = \"vdis\" departLane = \"random\" departSpeed = \"max\"',  
            '--additional-file', 'vdis100.add.xml',
            '--route-file', 'route_abc.xml']))
           
subprocess.Popen(["C:\Program Files (x86)\Eclipse\Sumo\\bin\sumo-gui.exe", "-c", "simexp.sumo.cfg",
            "--log", "log_file.xml",
            "-r", "route_abc.xml",
            "--remote-port", str(now_port), "-S", "true", "-Q", "true",
            "--emission-output", "CoEMS19ms.xml",
            "--tripinfo-output", "SummaryOP.xml",
            "--fcd-output", "CoTrace19ms.xml",
            "--output-prefix", op_path_file], stdout=sys.stdout, stderr=sys.stderr)

#CODE END---------------  

But for some reason, Randomtrips or duarouter is not generating a new  'route_abc.xml' and the simulation keeps running the simulation with the old 'route_abc.xml' which was already there in the folder previously. Please help me what am I doing wrong and how I can solve this.

P.S: I have the SUMO 1.1.0 Installed
