Re: [sumo-user] sub-microscopic model
Yes.
- you can remote control vehicle speeds via TraCI (if your model computes accelerations, you need to convert this to the resulting speed first)
- you can remote control vehicle positions directly

see https://sumo.dlr.de/docs/TraCI/Change_Vehicle_State.html

Good morning. 

Thanks for answering.

I'am using Windows and in the Plexe website they say "On Windows instead, building Plexe still requires manual steps (such as downloading external libraries), which is highly inefficient" (https://plexe.car2x.org/building/).

So I think my only option is using TraCI. I have used TraCI a bit but I don't understand how I can use it to simulate vehicle dynamics. I want to realize a controller in Matlab or Python and I want to send the control input to SUMO. Is it possible? 

Alternatively I can read the position of the vehicle from SUMO, calcolate the control input and the relative system evolution in Matlab or Python and send the new position to SUMO for the next simulation step. Is this possible?

Thank you,

Regards,

Fra

Hello,
SUMO doesn't really have sub-microscopic features.
The most sub-microscopic component are maybe the Plexe engine models that are integrated in SUMO (https://plexe.car2x.org/tutorial/example4/).
However, you can add microscopic modelling to SUMO by attaching your own process to the simulation via the TraCI-API (https://sumo.dlr.de/docs/TraCI.html).

Hi,

I'd like to know how to simulate in SUMO with a sub-microscopic model of the traffic (if it is possible).

Regards,
