Bonjour André,
you are doing what I'm dreaming of:
- model every day traffic jams in your neighborhood with SUMO
Here is the description of TLS:
https://sumo.dlr.de/docs/Simulation/Traffic_Lights.html
I would add in the TLS Program two lines for the EW-Traffic, one
actuated with min/max times and green for EW/WE
The next phase with red for EW, but green for EW.
Can you send me (directly) your scenario (so we are on the same page)?
Then I can play a little bit.

Hello,
generally, users of SUMO are expected to build their own scenarios.
There are plenty of tools to make this easy (e.g.
https://sumo.dlr.de/docs/Tutorials/OSMWebWizard.html)
After completing this other tutorial:
https://sumo.dlr.de/docs/Tutorials/Hello_World.html#demand_generation_in_netedit
you should be able to create the desired traffic demand ('flows')
with Netedit.

Jakob
Thanks for your reply, Jakob.
But isn't there really somewhere I can find an example of an already
made example of the simplest crossing there may be with Actuated
Traffic Light?
Asking someone to learn sumo is like asking to learn to use JOSM.
To draw the complete picture, I was somehow involved in a town council
discussion about that road crossing where a file builds up explained
below. I told them that one cannot without prior computer simulation
request to lengthen a green phase when actually the thing to do is to
add a red phase the other side, and even more build a costly
roundabout when the nearby town showed that it's a file builder. And
this is how, quickly browsing for simulators, I discovered sumo.
But I'm afraid I have absolutely no time to devote to learning to use
sumo from scratch.
Changing a few parameters, I could, maybe.
The best I could do is to find convincing Youtube sumo animation of
similar typologies and suggest that someone used sumo.
Thanks again.
All the best,
André.

Hi all,
SUMO is simply astounding !!! Congratulations.
Could someone kind make us a double SUMO configuration.
A simple road crossing
<https://www.openstreetmap.org/?mlat=50.53945&mlon=5.65262#map=19/50.53945/5.65262>
with Actuated Traffic Lights (current loops in the ground).
Sole peculiarity: most cars coming from west turn left to the
north road.
We can make all cars do that for simplicity.
The cars coming from the east are in the way of those turning left.
Even under sparse eastern traffic, they do not dare turning.
Western traffic is heavier and a long line builds up on the west
road.
In a second configuration the west-east green phase should be
split in two.
During some part of the time, it should be red on the east side.
This is to prove that partially stopping eastern traffic reduces
the west line much.
I would try to make a video (on Ubuntu)
I don't know SUMO that deep, I just made a tutorial.
But I'm used to figure already made configs.
TIA TIA TIA !!!
All the best,
André.
