Sumo | fast upload for iOS | Frontend Framework library

I'm running Sumo using Traci. I generate my own reports, and don't like Sumo to generate any other report. My .sumocfg file also doesn't request any output (see below). However, Sumo still generates 5 output files upon every run. Is there a way to disable that? My running command:

By default, SUMO used the Krauss Car-following model, is it possible to change the parameter, and how? Secondly, how can I also change from the default car-following to the lane-changing model in SUMO? Thank you in anticipation of your answer.

I want to subscribe to vehicles in my simulation. However, I find it very difficult to understand which variables I can use for this, as the documentation does not include this information.

In the TraCi doc I found the method for retrieving the current simulation time via connection.simulation.getTime() but no method to set it. I specifically want to reset it to zero.

Is that possible and how do I do it?

This is the link to the page in the doc where I found getTime().

I recently generated a Sumo scenario using OSMWebWizard.py. Then, using NetEdit, I added the edges to osm.net.xml and saved the extra 6 routes in a file calling it extra.rou.xml with its demands.

I would like to know how to append extra.rou.xml to my current scenario, so the SUMO will understand these 6 routes are also part of the scenario when running the run.bat file?

I'd like to use OMNeT++ along with Veins 5.1, Sumo 1.8 in Ubuntu 20.04 and I keep getting an error involving the setApiVersion that recommends to use Sumo 0.32 or Sumo 1.0.1. Is there any way to overcome that and use a later version of Sumo?

I have run the quick start tutorial of SUMO and it is working fine (https://sumo.dlr.de/docs/Tutorials/quick_start.html).

I want to understand the purpose of Internal edge as it is not touched in the quick start tutorial, though mentioned in the tutorial code on github: (https://github.com/eclipse/sumo/blob/master/tests/complex/tutorial/quickstart/data/quickstart.net.xml).

I have read the internal edge details: https://sumo.dlr.de/docs/Networks/SUMO_Road_Networks.html#internal_edges

My question is:

1. What is the benefit of using internal edge?

2. Do we have to define internal edges manually as I couldn't find option in netedit (i have latest version)

3. Is it always required to define internal edge.

Thanking you in advance.

I'm compiling systemd version 237 from source in a cross compiling environment (yocto sumo).

By the bitbake recipe, systemd is built by meson.

I upgraded meson version to 0.49.2 (copied from warrior) since my other recipes require that version.

when I do bitbake systemd, I have this error:

meson.build:678:0: ERROR: Program or command 'getent' not found or not executable

I opened meson.build and it has:

I've been using Veins (v5.1) along with SUMO (v1.8) and OMNeT++ (v5.6.2) in Linux Ubuntu 20.04 and 18.04. When I try to run the example provided by veins I keep getting the same error both in Ubuntu 20.04 and 18.04.

According to the information in OMNeT, the error code is 133 or 137 and there isn't much information about the error in the above lines.

Sumo seems to be running correctly, listening on port 9999, and sumo-gui is actually launching. However, a few seconds later it terminates with the following error log "Error: Storage::readChar(): invalid position". There's also an error code in the terminal.

In the past I faced this problem in Ubuntu 14.04 due to incompatibility issues between the versions I was using. This time I'm using the recommended versions from veins webpage. Has anyone faced this problem before? Could this be an incompatibility issue with the operating system and if so, does anyone know what the compatible versions are for Ubuntu 18.04 or 20.04? I haven't used Linux before so I'm not sure if there's something else I'm missing.

I've included a screenshot with the errors I'm getting in case that helps.

Thanks!
