Dynamic traffic assignment integration with real-time ramp metering for large-scale network management

As the dynamics of traffic patterns and increased congestion result in challenging problems on road systems, a vast number of real-time corridor management strategies have been introduced in the field of transportation. This study integrates a mesoscopic dynamic traffic assignment simulation model with existing responsive ramp metering strategies. The purpose of this paper is to introduce an initial platform of the integrated planning model as a comprehensive, practice-ready tool. We analyzed the local and regional impacts of ramp metering in a real-world traffic network in Maryland with considering minute-by-minute demand-supply interactions.
