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

["Mani Amoozadeh" <mani.amoozadeh2@xxxxxxxxx>]

Hello,

 

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, meaning calling simulationStep(0)  and getting subscription results without advancing the simulation?

 

Thank you.
