Fixed Time Traffic Light parameters

Hello,

I would like to know whether the green_phase/yellow_phase duration in the fixed time traffic light was same as the action repeat duration in the RL based approaches.

Thank you.

The yellow_phase durations default to the values declared in the command line argument for all traffic signal controllers.

The green_phase duration command line argument is the same for the fixed time traffic light and DQN-based RL controller.

However, the DDPG based controller's action selection dictates the duration of the next green phase.
