Impacts of Covid-19 mode shift on road traffic
Yue Hu, William Barbour, Kun Qian +3
This work considers the sensitivity of commute travel times in US metro areas due to potential changes in commute patterns, for example caused by events such as pandemics. Permanen…
Congestion Barcodes: Exploring the Topology of Urban Congestion Using Persistent Homology
Yu Wu, Gabriel Shindnes, Vaibhav Karve +4
This work presents a new method to quantify connectivity in transportation networks. Inspired by the field of topological data analysis, we propose a novel approach to explore the…
A convex formulation of traffic dynamics on transportation networks
Yanning Li, Christian G. Claudel, Benedetto Piccoli +1
This article proposes a numerical scheme for computing the evolution of vehicular traffic on a road network over a finite time horizon. The traffic dynamics on each link is modeled…
A Collapsed Generalized Aw-Rascle-Zhang Model and Its Model Accuracy
Shimao Fan, Ye Sun, Benedetto Piccoli +2
This work presents a collapsed generalized Aw-Rascle-Zhang (CGARZ) model, which fits into a generic second order model (GSOM) framework. GSOMs augment the evolution of the traffic…
Using coarse GPS data to quantify city-scale transportation system resilience to extreme events
Brian Donovan, Daniel B. Work
This article proposes a method to quantitatively measure the resilience of transportation systems using GPS data from taxis. The granularity of the GPS data necessary for this anal…
