Smart Edge-Enabled trAffic Lights (SEAL)

Implementation of Federated Reinforcement Learning for traffic control using SUMO and a real-world testbed.

The goal of this project is to provide a platform for simple single- and multi-agent reinforcement learning (RL) and federated reinforcement learning (FedRL) for smart traffic light control. The traffic simulator we use is SUMO.

Multi-Agent FedRL

We consider a multi-agent approach for FedRL using the OpenAI Gym interface. The gym for this scenario is defined as follows:

class MultiAgentEnv(gym.Env):
    def step(self, action_n: List[Any]) -> Tuple:
        obs_n = list()
        reward_n = list()
        done_n = list()
        info_n = {"n": []}
        # ...
        return obs_n, reward_n, done_n, info_n

For the multi-agent environment, we will use the MultiAgentEnv class provided by the RlLib API.
