Re: [sumo-user] Simulation Step TraCI call at time 0

when you take a look at the gui, you will find that the first call of
simulationStep(0) advances the simulation to the end of step 0 (with vehicles departing at 0 already being inserted).
Only the command simulation.getCurrentTime() already shows you 0.5 because all further traci calls will be processed at the start of the step that ends at 0.5
However, any vehicle positions you retrieve after the first call to simulationStep will be the ones from the insertion step 0.

I setup a SUMO simulation with 0.5s time step in TraCI mode.

Once the TraCI is established I subscribe to departed vehicles count and
then insert 10 vehicles at time 0s.

I call simulation step like this:

simulationStep(500) --> simulationStep(1000) --> simulationStep(1500) .

The first simulationStep returns subscription result that all 10 vehicles
have departed.

Is there any way to call simulationStep like this:

simulationStep(0)  --> simulationStep(500) --> simulationStep(1000) -->
simulationStep(1500) .

So that the first simulationStep call give me the subscription result
showing that all vehicles have departed.

Apparently, I cannot do this since 0 has a special meaning and proceeds
simulation to 500ms.

Is there any workaround for this?

Thank you.
