摘要: 针对多汇入区走廊中多簇交通波传播难以协同调控,且现有方法缺乏跨区域协同与精细化调控能力的问题,本文提出一种基于深度强化学习的分布式车辆群体协同控制方法。首先,根据汇入区结构与控制对象对走廊进行单元划分与分组,构建可扩展的模块化架构,实现对走廊交通系统的统一建模,从而将多簇交通波消散问题转化为多智能体协同决策问题。其次,考虑交通流交互特性对瓶颈通行能力的动态影响,协同设计状态空间与奖励函数,构建面向车辆群体的车道级速度控制模型。最后,基于多智能体近端策略优化算法训练分布式控制策略,通过多车道限速联合决策实现车道层协同调控,以提升多瓶颈交通系统的整体运行性能。仿真结果表明,控制周期为30s时,所提方法在停车次数、平均等待时间和潜在碰撞次数上分别降低49.88%、80.65%和26.84%。该方法将控制粒度由路段级细化至车道级,控制范围由单瓶颈拓展至多瓶颈,实现了交通系统跨层级的协同优化。

Abstract: To address the difficulties of cooperatively regulating multi-cluster traffic waves in a freeway corridor, as well as the limitations of existing methods in cross-region coordination and fine-grained control, this paper proposes a distributed cooperative vehicle-group control method based on deep reinforcement learning. First, the corridor is divided into some units and groups according to the merge-area structure and control objects. A scalable modular architecture is then constructed to enable unified modeling of the corridor traffic system, which transforms the dissipation of multi-cluster traffic waves into a multi-agent cooperative decision-making problem. Second, considering the dynamic influence of traffic-flow interactions on bottleneck capacity, the state space and reward function is designed, and a lane-level speed control model for vehicle groups is developed. Finally, a distributed control policy is trained based on the multi-agent proximal policy optimization algorithm. Lane-level cooperative regulation is achieved through joint decision-making of multi-lane speed limits, which improves the overall operational performance of the multi-bottleneck traffic system. Simulation results show that the proposed method reduces the number of stops, average waiting time, and potential collisions by 49.88%, 80.65% and 26.84% respectively under a control interval of 30 seconds. By refining the control granularity from the road-segment level to the lane level and extending the control scope from a single bottleneck to multiple bottlenecks, the proposed method realizes the cross-level collaborative optimization of traffic system.

Key words: intelligent transportation, cooperative control, multi-agent proximal policy optimization (MAPPO), multi-bottleneck corridor, deep reinforcement learning
