Hi Iñaki,
obviously I have no clue either what could be behind the exception. Do you
get any message from sumo-gui when it crashes? Sometimes you get some
message only on the console, so maybe start sumo-gui from the command line.
You can still run your TraCI script if you connect the TraCI client to the
chosen port (see docs <https://sumo.dlr.de/docs/TraCI.html#sumo_startup> ,
Python TraCI API reference <https://sumo.dlr.de/pydoc/traci.main.html>
connect()).
If you still don't make any progress afterwards, you can send me the files
to assess the problem.
Best regards
Mirko

Hi Mirko,
Thank you for your response. Regarding this issue, I have continued working
trying to simulate a shuttle of some vehicles so they maintain formation
for the whole simulation. I tried to change car-following and lane change
parameters but without having success.
My next approach has been in every step of the simulation, move the
follower vehicles to a previous position of the leader vehicle. In the
example I attached, just a leader and a follower, always crashes in step =
22 with no specific logs, just "Exception has occurred: FatalTraCIError". I
attached two pictures to better understand the simulation. These are from
the step before the simulation crash. What could be the cause? Thank you.
Best Regards,
Iñaki

Hi Iñaki,
I can confirm that your goal cannot be achieved using simpla, as this
module is meant to form platoons spontaneously. It may work in some
networks with few lane changes and platooning vehicles following the same
route, but cannot be guaranteed at all. The vehicles still act
indepedently: they may let other vehicles change onto their lane, stop at
traffic lights while the front vehicle passed etc.
In theory, TraCI includes all the tools to control the vehicles remotely
and implement your own platooning algorithm:
* enable / disable speed and lane change checks
* overrule speed, issue lane changes
This control does not necessarily happen all the time, but you need to
step in at critical points like intersections.
Best regards
Mirko

Hello,
I recently started working with the Simpla module in SUMO, researching
what can be done regarding platooning.
From what I have tried so far, the vehicles enter and leave platooning
mode depending on the conditions of the simulation and the simpla
configuration. What I would like to achieve is to create a platoon of,
let's say, 5 vehicles, and those 5 vehicles keep their formation during
all the simulation (representing a shuttle). What I have achieved so far
is that these vehicles form the platoon at the start of the simulation
but as the simulation goes on, they leave the formation and change lanes
and leave platooning mode.
Is it possible to achieve what I am looking for? Any tips on how to do
it? Thank you.
Regards,
Iñaki
