ABSTRACT:
The Network Fundamental Diagram (NFD), also known as Macroscopic Fundamental Diagram (MFD), represents dynamics of traffic flow at the network level. It is exploited to monitor traffic state and design various network-wide traffic control and pricing strategies to improve mobility and mitigate congestion in urban networks. In this study, three applications of NFD are explored using a state-of-the-art dynamic traffic assignment simulation tool, DYNASMART. The first application includes improving travel time reliability coefficient estimation using network partitioning based on NFD. Then, a macroscopic emission model is proposed incorporating NFD and vehicle type market penetration rates. Finally, the NFD is used to demonstrate the network-wide impacts of incorporating connected and autonomous vehicles.
