Veins: Load SUMO's Additional Files for Simulation Output

[Daniel Febrian Sengkey]

Hi all,

I want to produce the edge-based traffic measure as defined in [1]. Therefore I made my additional file named main.add.xml and load it as the other xml configuration files to my main.launchd.xml.

My main.add.xml looks like this:
<additional>
    <edgeData id="edgebased" file="main-out.xml" />
</additional>

main.launchd.xml like this:
<launch>
    <copy file="main.net.xml" />
    <copy file="main.rou.xml" />
    <copy file="main.add.xml" />
    <copy file="main.settings.xml" />
    <copy file="main.sumo.cfg" type="config" />
</launch>

main.sumo.cfg
<configuration>
    <input>
        <net-file value="main.net.xml" />
        <route-files value="main.rou.xml" />
        <gui-settings-file value="main.settings.xml" />
        <additional-files value="main.add.xml" />
    </input>

... (omitted).

My simulation (while run in couple mode of Veins+SUMO) yields no output file (main-out.xml), but when I tested the scenario only with SUMO the expected result file was produced. I notice that in the erlangen example configuration a poly.xml was loaded into simulation.

Does simulation loaded in coupled with Veins only load additional file which supporting the map (such as poly.xml) and not for the simulation output?

How do I get the expected result file?

Thanks in advance.

Best regards,

Daniel

Dear Daniel,

If you use sumo-launchd, your simulations will be started in a temporary
folder (to allow you to run multiple simulations in parallel, without
them conflicting). This means, your output files will land in a
temporary folder (and be deleted after the simulation terminates). To
work around this, you can turn off deletion of temp folders in the
launchd, or you could try setting an absolute path for the output file.

Best,

Christoph

Oh I see. Thank you very much Dr. Sommer.

Dear Dr. Sommers,

I was also facing the same problem so I tried both of your methods. Good part is I am able to get the output file but it contains only the starting comment section shown below. Please assist.
