Re: [sumo-user] Loading simulation state fails after collision (stop on

[Marcelo Andrade Rodrigues D Almeida <md@xxxxxxxxx>]

Thank you

I just tested with the latest development version

RUN curl https://sumo.dlr.de/daily/sumo-src-git.tar.gz \

| tar -xz

ENV SUMO_HOME=sumo-git

RUN mkdir sumo-git/build/cmake-build && cd sumo-git/build/cmake-build \

&& cmake ../.. && make -j$(nproc)

I'm still finding the same error (I don't know if it is the same cause, though)

See attached save states

Error:

Warning: Vehicle '-gneE3__gneE1__light.50'; collision with vehicle '-gneE1__gneE2__light.38', lane=':gneJ0_15_0', gap=-1.00, time=1482.00 stage=move.
Error: stop for vehicle '-gneE1__gneE2__light.38' on lane ':gneJ0_8_0' is not downstream the current route.

Hi everyone

I was running my application and found this error (Sumo version 1.8.0):

"Error: stop for vehicle '-gneE0__gneE3__light.42' on lane ':gneJ0_2_0' is not downstream the current route.
Quitting (on error).
'Connection' object has no attribute '_socket'"

This error occured after loading a state, saved after the following collision:

Step #1830.00

Warning: Vehicle '-gneE0__gneE3__light.42'; collision with vehicle '-gneE2__gneE0__light.46', lane=':gneJ0_2_0', gap=-1.00, time=1830.00 stage=move.

To reproduce the error locally, I loaded the state manually in my machine

Loading through python, I receive pretty much the same error, but for car 46 instead.

Alternatively, if I try to load it through the sumocfg and sumo-gui, I receive this error:

sumo files + script attached

Thank you in advance

Sincerely,

Marcelo d'Almeida
