标题： A Multi-scale Perimeter Control and Route Guidance System for Large-scale Road Networks

摘要： 通过控制网络上的空间和时间交通分布，周界控制和路径引导是减少交通拥堵和提高交通效率的有效方法。 本文提出了一种多尺度联合周界控制和路径引导（MSJC）框架，用于控制大规模网络中的交通。 首先将网络划分为几个子网络（区域），每个区域的交通由其宏观基本图（MFD）进行管理，这形成了宏观尺度网络（上层）。 每个子网络由实际的道路链接和信号交叉口组成，形成了微观尺度网络（下层）。 在上层，联合周界控制和路径引导模型求解基于区域的流入率和超路径流量，以控制每个区域的累积量，从而最大化每个区域的吞吐量。 在下层，一种与反压策略集成的周界控制策略确定区域边界处交叉口的最佳信号相位。 同时，构建了一个车辆路径选择模型，以满足超路径流量并确保区域内交通密度的一致性。 案例研究结果表明，所提出的MSJC在调节区域累积方面优于其他基准，从而提高了吞吐量。 显示英文摘要

摘要： Perimeter control and route guidance are effective ways to reduce traffic congestion and improve traffic efficiency by controlling the spatial and temporal traffic distribution on the network. This paper presents a multi-scale joint perimeter control and route guidance (MSJC) framework for controlling traffic in large-scale networks. The network is first partitioned into several subnetworks (regions) with traffic in each region governed by its macroscopic fundamental diagram (MFD), which forms the macroscale network (upper level). Each subnetwork, comprised of actual road links and signalized intersections, forms the microscale network (lower level). At the upper level, a joint perimeter control and route guidance model solves the region-based inflow rate and hyper-path flows to control the accumulation of each region and thus maximize the throughput of each region. At the lower level, a perimeter control strategy integrated with a backpressure policy determines the optimal signal phases of the intersections at the regional boundary. At the same time, a route choice model for vehicles is constructed to meet hyper-path flows and ensure the intra-region homogeneity of traffic density. The case study results demonstrate that the proposed MSJC outperforms other benchmarks in regulating regional accumulation, thereby improving throughput.
