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

[Andras Bondor <andras.bondor@xxxxxxxxxxxx>]

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

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

 

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
