Traffic light synchronization in co-simulation between carla and vissim

[Intelligentcar]

Hi,

I'm on the way of setting up co-simulations between carla and vissim considering traffic signal interactions.

I use 'Co-Simulation/PTV-Vissim/examples/Town01/Town01.inpx' which was already given from carla, but the
'inpx' file doesn't have any traffic signal controllers.

So, I directly established the signal controllers in the 'inpx' file according to the map of 'Town01' in the CarlaUE4 window,
as shown in the below (red lines on the map).
Then, I want to synchronize the carla's traffic signals to the vissim traffic signal controllers.

I think it should be implemented by PTVVissimSimulation class in 'vissim_simulation.py'.

How could I set the vissim traffic signals with carla's signal in the same?
