Hello Jakob, Ok, now I understand better the action-step-length option. However, I need to reflect a delay in action application while training the reinforcement learning agent. Indeed, in real-world a brake decision at t (k) is executed at t (k + 2) due to the vehicle transmission mechanisms which require some time to transmit the driver maneuver until wheels. Is there any functionality in SUMO that can support such training?
