Hello again,

Not being impatient, just wondered if there are any updates on this, or if 
there is something I can do on my end to get the desired behavior.

Thank you,
Andras

Tárgy: Re: [sumo-user] Junction edge is not included in Route, Vehicle is being 
invisible while in junction

Hello Jakob,

Thank you for your quick reply. Please see attachment. The issue can be 
reproduced by starting to move forward with the remote-controlled vehicle after 
an arbitrary wait time.

Is this a configuration issue on my end?

Thank you again for your time!

Andras

Hello,
- internal edges are never included in a route definition (they can be deduced 
from the "normal" edges at simulation time)
- except for some special junction configurations where right-of-way rules do 
not apply, the vehicle should be visible to the others while on the junction 
(at least it works in our nightly test). Please provide input files for 
reproducing the issue. Instead of sending your whole traci script, you may use 
the tracing functionality: 
https://sumo.dlr.de/docs/TraCI/Interfacing_TraCI_from_Python.html#generating_a_log_of_all_traci_commands

regards,
Jakob

Hello,

I'm experiencing an interesting behavior when calculating a route that should 
contain a junction and when navigating over it using moveToXY().

First, I'm building a route for the remote-controlled vehicle by calling 
libsumo::Simulation::convertRoad() on the current and target positions.
Then I feed these two edge ids to libsumo::Simulation::findRoute() to get a 
route. The start route and end route are two straight lines, connected with a 
simple junction. I'm observing that the generated route only has 2 edges, the 
current and target edge, but the edge in the junction is not included in the 
route.

Now if I start the simulation and I move my remote-controlled vehicle by 
calling the moveToXY() function the vehicle is correctly positioned. I'm 
querying the edge id on each step and it correctly reports the starting, 
in-junction, and target edges as it moves over them.

However, while being in the junction, and being on the edge id which belongs to 
the junction (which isn't part of the route), the vehicle seems to be invisible 
to other participants controlled by SUMO, and they simply drive through it. 
Once the remote-controlled vehicle is out of the junction, all other vehicles 
are correctly slow down around it not to collide. I read that the in-junction 
collisions are expected if the remote-controlled vehicle doesn't have a route 
continuing after the end of the junction, but here it is not the case.

Originally I used version 1.6.0 but upgraded to 1.7.0 and I'm experiencing the 
same behavior.

Any help is appreciated.

Thank you,
Andras
