摘要:

交通信号控制是缓解城市交通拥堵的基础和关键。然而,这是具有挑战性的,因为在现实世界的场景中,交通动态是复杂的。由于交通建模的优化问题的高度复杂性,现有工程的实验设置往往是不一致的。此外,由于其庞大的状态和动作空间,在实际复杂的交通场景中,适当地控制多个交叉口并不是小事。不考虑交叉点拓扑关系也会导致较差的解决方案。为了解决这些问题,在这项工作中,我们仔细设计了我们的设置,并提出了一个新的数据集,包括合成和真实的交通数据在更复杂的情况下。此外,我们提出了一种新的基线模型具有强大的性能。它基于深度强化学习,具有编码器-解码器结构:边缘加权图卷积编码器,用于挖掘多交叉关系;统一结构解码器,用于以综合方式联合建模多个交叉点,从而显着减少模型参数的数量。通过这样做,该模型能够有效地处理多路口交通优化问题。使用城市交通仿真(SUMO)模拟器在合成和真实地图以及交通数据上对模型进行训练/测试。实验结果表明,该模型优于多种竞争方法。

英文摘要:

The control of traffic signals is fundamental and critical to alleviate traffic congestion in urban areas. However, it is challenging since traffic dynamics are complicated in real-world scenarios. Because of the high complexity of the optimisation problem for modelling the traffic, experimental settings of existing works are often inconsistent. Moreover, it is not trivial to control multiple intersections properly in real complex traffic scenarios due to its vast state and action space. Failing to take intersection topology relations into account also results in inferior solutions. To address these issues, in this work we carefully design our settings and propose a new dataset including both synthetic and real traffic data in more complex scenarios. Additionally, we propose a novel baseline model with strong performance. It is based on deep reinforcement learning with an encoder-decoder structure: an edge-weighted graph convolutional encoder to excavate multi-intersection relations; and an unified structure decoder to jointly model multiple junctions in a comprehensive manner, which significantly reduces the number of the model parameters. By doing so, the proposed model is able to effectively deal with the multi-intersection traffic optimisation problem. Models are trained/tested on both synthetic and real maps and traffic data with the Simulation of Urban Mobility (SUMO) simulator. Experimental results show that the proposed model surpasses multiple competitive methods.
