Hi Simon,
there are more options to output acceleration values and process them.
Using TraCI may slow down your simulation compared to one of our other
output options. For plotting accelerations, FCD output
<https://sumo.dlr.de/docs/Simulation/Output/FCDOutput.html> combined with
the plotXMLAttributes.py
<https://sumo.dlr.de/docs/Tools/Visualization.html#plotxmlattributespy>
script should do fine.
Best regards
Mirko

Thank you so much, Jerry! Okay, I will try the TraCI API.
Kind Regards

Hello Simon,
Have you considered using TraCI API? You can use Python to access
TraCI-specific functions which you can use to collect acceleration data
at every timestep. You can access TraCI documentation (including simple
applications) here. <https://sumo.dlr.de/docs/TraCI.html> For more
specific commands, you can find a list here
<https://sumo.dlr.de/docs/TraCI/Vehicle_Value_Retrieval.html> and here
<https://sumo.dlr.de/pydoc/traci._vehicle.html#VehicleDomain> .
A simple command for accessing the acceleration would look something
like:
accel = traci.vehicle.getAcceleration(veh_id)
Alternatively, you can choose to subscribe to each vehicle upon injection
into the network (info
<https://sumo.dlr.de/docs/TraCI/Object_Variable_Subscription.html> for
variable subscription)
You can save the accel value into a dictionary with a key for each veh_id
and use matplotlib to create your profile.
Hope that this helps.
Jerry

Hello Everyone,
I am a new user of SUMO software and I am interested in simulating the
traffic flow of fully Connected and Automated Vehicles by adjusting the
IDM model parameters. I want to generate acceleration profiles for each
vehicle in the simulation. Does anyone have any suggestions or
references for this task? I would appreciate any help or guidance.
Thank you
