Addressing First-In-First-Out in System Optimal Dynamic Traffic Assignment on Multi Origin-Destination Networks
Résumé
In this paper, we present a System Optimal Dynamic Traffic Assignment (SO-DTA) framework for multidestination networks, incorporating hierarchical First-In-First-Out (FIFO) principles at junctions and system-wide levels. Junction level FIFO, also known as local FIFO, ensures orderly traffic flow and proportional distribution at diverging links per destination. System-wide FIFO, or Global FIFO, maintains consistent vehicle-to-destination ratios across all Origin-Destination (OD) pairs. We expand existing mathematical programming frameworks for SO-DTA to include such FIFO constraints. Our model also includes a link-level macroscopic fundamental diagram (MFD) approach for a more accurate representation of link travel times compared to traditional triangular FD and a generic cost function, enhancing the optimization framework's flexibility to accommodate different objectives such as Total System Travel Time (TSTT) and Total System Emissions (TSE). Additionally, we have ensured perfect compatibility between the new FIFO constraints and the usual Non-Vehicle Holding (NVH) ones that are necessary in SO-DTA mathematical programming frameworks.
