The expansion of road infrastructure, in spite of increasing congestion levels, faces severe restrictions from all sorts: economical, environmental, social, or technical. An efficient and, usually, less expensive alternative to improve mobility and the use of available infrastructure is the adoption of traffic management. A particular case of interest occurs when inbound and outbound traffic on a given facility is unbalanced throughout the day. This scenario may benefit of a lane management strategy called tidal flow (or reversible) lane control, in which case the direction of one or more contraflow buffer lanes is reversed according to the needs of each direction. This paper proposes a simple and practical real-time strategy for efficient motorway tidal flow lane control. A state-feedback switching policy based on the triangular fundamental diagram, that requires only aggregated measurements of density, is adopted. A theoretical analysis based on the kinematic wave theory shows that the strategy provides a Pareto-optimal solution. Microsimulations using empirical data from the A38(M) Aston Expressway in Birmingham, UK, are used to demonstrate the operation of the proposed strategy. The robustness of the switching policy to parameter variations is demonstrated by parametric sensitivity analysis. Simulation results confirm an increase of motorway throughput and a smooth operation for the simulated scenarios.

高速公路潮汐车道控制

尽管拥堵程度不断增加，道路基础设施的扩张仍面临着来自各种方面的严格限制：经济、环境、社会或技术。提高移动性和使用可用基础设施的一种有效且通常成本较低的替代方案是采用交通管理。当给定设施的入站和出站流量全天不平衡时，就会发生一种特殊情况。这种情况可能受益于称为潮汐流（或可逆）车道控制的车道管理策略，在这种情况下，一个或多个逆流缓冲车道的方向根据每个方向的需要进行反转。本文提出了一种简单实用的实时策略，用于高效的高速公路潮汐流车道控制。采用了一种基于三角基本图的状态反馈切换策略，该策略只需要对密度进行聚合测量。基于运动波理论的理论分析表明，该策略提供了帕累托最优解。使用来自英国伯明翰 A38(M) 阿斯顿高速公路的经验数据的微观模拟被用来演示所提议策略的操作。参数敏感性分析证明了切换策略对参数变化的鲁棒性。模拟结果证实了高速公路吞吐量的增加和模拟场景的平稳运行。使用来自英国伯明翰 A38(M) 阿斯顿高速公路的经验数据的微观模拟被用来演示所提议策略的操作。参数敏感性分析证明了切换策略对参数变化的鲁棒性。模拟结果证实了高速公路吞吐量的增加和模拟场景的平稳运行。使用来自英国伯明翰 A38(M) 阿斯顿高速公路的经验数据的微观模拟被用来演示所提议策略的操作。参数敏感性分析证明了切换策略对参数变化的鲁棒性。模拟结果证实了高速公路吞吐量的增加和模拟场景的平稳运行。
