Hi Simon,
this is not the place to seek for general programming help. I see several
problems in the first lines (size of colors vs. for loop), but won't go
further. Please describe more in detail which problems you encountered
regarding sumo / TraCI if you managed to make it run.
Best regards
Mirko

Hi Everyone,
I am working on a project that involves simulating five passenger vehicles
with different colors on four routes. I want to generate the acceleration
of each vehicle at each time step. The vehicles have the following
specifications:
- one yellow and one green color vehicle starts from route 1 and travels
via route 2 and 3 to reach route 4.
- One green and one red vehicle starts from route 2 and travels via route 3
to reach Route 4.
- One magnetic vehicle starts from route 3 and reaches route 4 directly.
However, I encountered some problems with my Python TraCI code and it could
not run the simulation. I have attached the code for your reference. I
would appreciate any assistance or suggestions from you. Thank you.

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
