PTV VISSIM simulation data for efficient eco-ramp control project funded by NCST 18-19

Our current transportation system faces a variety of issues in terms of safety, mobility, and environmental sustainability. The emergence of innovative intelligent transportation system (ITS) technologies such as connected and automated vehicles (CAVs) and transportation electrification unfold unprecedented opportunities to address aforementioned issues. In this project, we propose a hierarchical ramp control system that not only allows microscopic cooperative maneuvers for connected and automated electric vehicles (CAEVs) on the ramp to merge into mainline traffic flow under certain controlled ramp inflow rate, but also enables macroscopic corridor-level traffic flow control (i.e., coordinated ramp metering rate determination). A centralized optimal control-based approach is proposed to both smooth the merging flow and improve the system-wide mobility of the network. Linear quadratic trackers in both finite horizon and receding horizon forms are developed to solve the optimization pro...当前的交通系统在安全、通行效率与环境可持续性层面面临诸多问题。以联网自动车辆（Connected and Automated Vehicles，CAVs）、交通电动化等为代表的创新智能交通系统（Intelligent Transportation System，ITS）技术的出现，为解决上述问题带来了前所未有的机遇。本项目提出了一种分层式匝道控制系统，该系统不仅能够在受控匝道流入率的约束下，实现匝道上的联网自动电动车辆（Connected and Automated Electric Vehicles，CAEVs）汇入主线车流的微观协同操控，还可实现宏观走廊级别的车流管控（即协调匝道调节率的确定）。本文提出了一种基于集中式最优控制的方法，以平滑汇入车流并提升全路网的系统通行效率。此外，开发了有限时域与后退时域两种形式的线性二次跟踪器，以求解该优化问题……
