[sumo-user] traci.vehicle.getIDList() giving error

Discussion:

Hi again,

I'm using TraCI (python) and have got a loop to loop through the simulation
steps (and move one simulation step using traci.simulationStep() per
iteration). Within this loop I'm using traci.vehicle.getIDList() to check
whether a particular car is within the simulation. All works well (even
this method call) till step 633. Once step 633 is reached, sumo will stop
and a window opens saying 'Simulation ended at time: 633.00 Reason: An
error occured (see log)'. I cannot figure out what could possibly be reason
as everything is the same as previous steps. Also, the log is remaining
empty. Does anyone have any idea how I can figure out what the problem is?

Thanks for all your help,
Kara

Hello,
can you run the simulation without TraCI and reproduce the error?
regards,
Jakob

Hi all, so it seems I've 'solved' the issue. What seems to have worked is
running the simulation using 'sumo' rather than 'sumo-gui'. Have no idea
how that worked.

What do you mean running it without traci? Just opening the config file
using sumo? I can try that no prob.

Thanks
