Calibrating MFD Models from Mobile Phone Data
This work focuses on the estimation ofMacroscopic Fundamental Diagram (MFD) and trip lengths for the city scale network using mobile phone data for the city of Dallas. The data used in the present work has different sampling intervals and in order to have an accurate estimation of travelled distance, a trip enhancement method is proposed based on m...
Perimeter gating control and citywide dynamic user equilibrium: A macroscopic modeling framework
In recent years, several perimeter control strategies have been proposed for traffic management in cities. The common factor found in these works is the use of Macroscopic Fundamental Diagram (MFD) models to describe the dynamics of the network and optimize traffic inside the perimeter by manipulating perimeter inflows. Perimeter gating control str...
Bi-modal macroscopic traffic dynamics in a single region
Bi-modal or 3D-MFD relates the accumulation of cars, buses to total production at the network level. The current work provides a detailed discussion of extended MFD-based models namely, accumulation-based and trip-based models that accounts for bi-modal flows through 3DMFD. In addition, delay accumulation-based models, also known as exit-flow model...

Reducing Network-wide Emissions Through Perimeter Control at City Gates
Traffic congestion and emission are the crucial problems due to its significant impact on the environment, economy, and health of the inhabitants. In this paper, we propose an approach to reduce network-wide emissions in an urban traffic network. The approach is comprised of two layers. The first layer (optimal green routing) which predicts the opt...

The role of trip lengths in Perimeter Control strategies
Since the development of the Macroscopic Fundamental Diagram (MFD), many traffic control strategies and algorigthms have been developed to implement perimeter control over a specific urban region. In most cases, the typical assumption is to have a common average trip length for all vehicles traveling within the same region. However, the proper cali...
