Decentralized Deep Reinforcement Learning for Network Level Traffic Signal Control [article]

Jin Guo
2020 arXiv   pre-print
Notably, S2R2L has the best testing performance of reducing 34.55% traffic delay and dissipating 10.91% queue length compared with MP.  ...  In this thesis, I propose a family of fully decentralized deep multi-agent reinforcement learning (MARL) algorithms to achieve high, real-time performance in network-level traffic signal control.  ...  On the opposite, IDQL reports the worst performance, not only in the measurements of 3 metrics, but also for its poor convergence.  ...
