Towards Integrated Traffic Control with Operating Decentralized Autonomous Organization
This work addresses the scalability and optimality issues in intelligent traffic systems for urban management, representing an incremental advancement in decentralized control frameworks.
The paper tackles the challenge of integrated traffic control by proposing a Decentralized Autonomous Organization (DAO)-based method that optimizes both global energy consumption efficiency and local agent objectives, achieving faster consensus and improved local performance compared to existing decentralized methods.
With a growing complexity of the intelligent traffic system (ITS), an integrated control of ITS that is capable of considering plentiful heterogeneous intelligent agents is desired. However, existing control methods based on the centralized or the decentralized scheme have not presented their competencies in considering the optimality and the scalability simultaneously. To address this issue, we propose an integrated control method based on the framework of Decentralized Autonomous Organization (DAO). The proposed method achieves a global consensus on energy consumption efficiency (ECE), meanwhile to optimize the local objectives of all involved intelligent agents, through a consensus and incentive mechanism. Furthermore, an operation algorithm is proposed regarding the issue of structural rigidity in DAO. Specifically, the proposed operation approach identifies critical agents to execute the smart contract in DAO, which ultimately extends the capability of DAO-based control. In addition, a numerical experiment is designed to examine the performance of the proposed method. The experiment results indicate that the controlled agents can achieve a consensus faster on the global objective with improved local objectives by the proposed method, compare to existing decentralized control methods. In general, the proposed method shows a great potential in developing an integrated control system in the ITS
