This paper formulates a cooperative traffic control methodology that integrates traffic signal timing and ramp metering decisions into an optimization model to improve traffic operations in a corridor network. A mixed integer linear model is formulated and is solved in real time within a model predictive controller framework, where the cell transmission model is used as the system state predictor. The methodology is benchmarked in a case study corridor in San Mateo, CA, in VISSIM with two optimization scenarios, namely, optimal metering and optimal signal control, and two simulation scenarios with a preset metering plan and no metering. The numerical results show that integrated traffic signal and ramp metering control reduces delays, stops, and travel times of the corridor by up to 33.1%, 36%, and 16.4%, respectively, compared to existing benchmark conditions. With appropriate weights prioritizing freeway or arterial street operations, the integrated control balances traffic congestion between the arterial street and the freeway.

通过协作交通信号和坡道计量控制进行综合走廊管理

本文制定了一种协作交通控制方法，将交通信号配时和匝道计量决策集成到优化模型中，以改善走廊网络中的交通运营。在模型预测控制器框架内制定混合整数线性模型并实时求解，其中单元传输模型用作系统状态预测器。该方法在 VISSIM 中的加利福尼亚州圣马特奥市的案例研究走廊中进行了基准测试，具有两种优化场景，即最优计量和最优信号控制，以及具有预设计量计划和无计量的两种模拟场景。数值结果表明，与现有基准条件相比，综合交通信号和匝道计量控制可将走廊的延误、停车和出行时间分别减少高达 33.1%、36% 和 16.4%。通过优先考虑高速公路或主干道运营的适当权重，综合控制可以平衡主干道和高速公路之间的交通拥堵。
