Hi Thiago,
I cannot reproduce the problem with my simple example scenario. Is the
timing more or less consistent if you do not call
traci.trafficlight.setPhase? Do you use the most recent SUMO release? If
you can confirm both, it would be great to have a minimal example scenario
to reproduce.
Best regards
Mirko

Betreff: [sumo-user] Traci and sumo gui inconsistent simulation speed

Hi Everyone,
I am having an issue when using sumo-gui and a Traci with the simulation
speed. Basically no matter what I set as the delay in the GUI I am getting
a lot of cycle times that are both longer (acceptable for certain
instantaneous steps where more processing is necessary), but I'm also
getting cycle times that are much shorter than the delay. For example I'm
measuring this in the runner.py , In the GUI I'm setting a delay of 200ms ,
and not only is the timing extremely inconsistent, it is not honoring the
value I set. the value in sumo sim is measured in ms around "traci.
simulationStep()".

My script is subscribing to events from 13 different traffic lights and is
controlling the phase of each of them via traci.trafficlight.setPhase(). Is
there a way to make each step a more consistent time? Is it the number of
lights I'm controlling? As far as I can tell the subscriptions aren't
causing the variablility, but setPhase() seems to.
I would appreciate any insight, or suggestions of things to try.
Regards,
Tiago Furtado
