Figure6 shows the training performance of two different HDV models (i.e., aggressive or politeness) under different traffic densities. We have re-run the ATSC experiments with SUMO 1.2.0 using the master code, and provided the following training plots as reference. Consensus multi-agent reinforcement learning for volt-var control in power distribution networks. In particular, we model the mixed-traffic lane-changing environment as a multi-agent network: \(\mathcal{G} = (\nu , \varepsilon )\), where each agent (i.e., ego vehicle) \(i \in \nu \) communicates with its neighbors \(\mathcal{N}_{i}\) via the communication link \(\varepsilon _{ij}\in \varepsilon \). Indeed, MA2C appears more robust performances, which shows a very clear increasing and plateauing tendency. Specifically, each agent learns a decentralized control policy based on local observations and . In addition, they assume that the HDVs follow unchanged, universal human driver behaviors, which is clearly oversimplified and impractical in the real world as different human drivers tend to behave quite differently. If the agent can only observe a part of the state \(s_{t}\), the underlying dynamics becomes a POMDP [26] and the goal is then to learn a policy that maps from the partial observation to an appropriate action to maximize the rewards. Therefore, it can be confirmed that the research results in this paper can provide a promising solution for autonomous air transportation management systems in city-wide urban areas. 2015. Transp.
