Re: [sumo-user] Warning: Vehicle '53' skips stop on lane '25301895_0' time=471.00

[Green M. <gre...@gm...>]

Jakob,

Thanks for the answer.

In this case, what is the difference between this error I sometimes I get
in my python script:
*traci.exceptions.TraCIException: Stop for vehicle '69' on lane
'-36948252_0' is too close to break.*

and this warning I get on Sumo log (and the python script is unaware of,
except for the vehicle disappearing)?
*Warning: Vehicle '53' skips stop on lane '25301895_0' time=471.00*

Are they both caused by the same reason? (not enough space to break before
the end of the lane)? What would cause one over the other?
