摘要:

我们参加了城市大脑挑战赛,并取得了第八名。在这场比赛中,玩家提供了一个真实的城市规模的道路网络,其交通需求来自真实的交通数据。玩家被要求与一个自行设计的代理协调交通信号,以最大限度地提高服务的车辆数量,同时保持一个可接受的延迟。在这篇摘要文章中,我们提出了一个全面的分析和我们的详细解决方案,这一竞争。我们的方法主要是基于适应的深度Q网络(DQN)的实时交通信号控制。从我们的角度来看,本次比赛的主要挑战是如何将经典的DQN框架扩展到现实世界复杂道路网络和交通流情况下的交通信号控制。在尝试和实现了几个经典的奖励函数之后,我们最终选择在我们的代理中应用我们新设计的奖励。通过应用我们新提出的奖励函数并仔细调整控制方案,基于单个DQN模型的代理可以跻身前15名团队。希望本文能在一定程度上为实际道路网络的交通信号控制提供一个基线解决方案,并对进一步的尝试和研究有所启发。

英文摘要:

We took part in the city brain challenge competition and achieved the 8th place. In this competition, the players are provided with a real-world city-scale road network and its traffic demand derived from real traffic data. The players are asked to coordinate the traffic signals with a self-designed agent to maximize the number of vehicles served while maintaining an acceptable delay. In this abstract paper, we present an overall analysis and our detailed solution to this competition. Our approach is mainly based on the adaptation of the deep Q-network (DQN) for real-time traffic signal control. From our perspective, the major challenge of this competition is how to extend the classical DQN framework to traffic signals control in real-world complex road network and traffic flow situation. After trying and implementing several classical reward functions, we finally chose to apply our newly-designed reward in our agent. By applying our newly-proposed reward function and carefully tuning the control scheme, an agent based on a single DQN model can rank among the top 15 teams. We hope this paper could serve, to some extent, as a baseline solution to traffic signal control of real-world road network and inspire further attempts and researches.
