Online Influence Maximization under Decreasing Cascade Model
Fang Kong, Jize Xie, Baoxiang Wang +2
We study online influence maximization (OIM) under a new model of decreasing cascade (DC). This model is a generalization of the independent cascade (IC) model by considering the c…
On the Continuum Approximation of the On-and-off Signal Control on Dynamic Traffic Networks
Ke Han, Vikash Gayah, Benedetto Piccoli +2
In the modeling of traffic networks, a signalized junction is typically treated using a binary variable to model the on-and-off nature of signal operation. While accurate, the use…
An Infinite-Dimensional Variational Inequality Formulation and Existence Result for Dynamic User Equilibrium with Elastic Demands
Ke Han, Terry L. Friesz, Tao Yao
This paper is concerned with dynamic user equilibrium (DUE) with elastic travel demand (E-DUE). We present and prove a variational inequality (VI) formulation of E-DUE using measur…
Urban Freight Transportation Planning: A Dynamic Stackelberg Game-Theoretic Approach
Bo Zhang, Tao Yao, Terry L. Friesz +1
In this paper we propose a dynamic Stackelberg game-theoretic model for urban freight transportation planning which is able to characterize the interaction between freight and pers…
A Link-based Mixed Integer LP Approach for Adaptive Traffic Signal Control
Ke Han, Terry L. Friesz, Tao Yao
This paper is concerned with adaptive signal control problems on a road network, using a link-based kinematic wave model (Han et al., 2012). Such a model employs the Lighthill-Whit…
Existence and Properties of the State Operator in Dynamic User Equilibrium
Terry L. Friesz, Ke Han, Tao Yao
In this paper, we establish and prove analytical properties of the state operator embedded in an optimal control problem, in the context of dynamic user equilibrium (DUE) models (F…
Lagrangian-based Hydrodynamic Model: Freeway Traffic Estimation
Ke Han, Tao Yao, Terry L. Friesz
This paper is concerned with highway traffic estimation using traffic sensing data, in a Lagrangian-based modeling framework. We consider the Lighthill-Whitham-Richards (LWR) model…
A robust optimization approach for dynamic traffic signal control with emission considerations
Ke Han, Hongcheng Liu, Vikash Gayah +2
We consider an analytical signal control problem on a signalized network whose traffic flow dynamic is described by the Lighthill-Whitham-Richards (LWR) model (Lighthill and Whitha…
Network User Equilibrium with Elastic Demand: Formulation, Qualitative Analysis and Computation
Terry L. Friesz, Ke Han, Amir Meimand +1
In this paper we present a differential variational inequality formulation of dynamic network user equilibrium with elastic travel demand. We discuss its qualitative properties and…
A variational approach for continuous supply chain networks
Ke Han, Terry L. Friesz, Tao Yao
We consider a continuous supply chain network consisting of buffering queues and processors first proposed by [D. Armbruster, P. Degond, and C. Ringhofer, SIAM J. Appl. Math., 66 (…
Existence of simultaneous route and departure choice dynamic user equilibrium
Ke Han, Terry L. Friesz, Tao Yao
This paper is concerned with the existence of the simultaneous route-and-departure choice dynamic user equilibrium (SRDC-DUE) in continuous time, first formulated as an infinite-di…
Second-order models and traffic data from mobile sensors
Benedetto Piccoli, Ke Han, Terry L. Friesz +2
Mobile sensing enabled by GPS or smart phones has become an increasingly important source of traffic data. For sufficient coverage of the traffic stream, it is important to maintai…
Competitive Robust Dynamic Pricing in Continuous Time with Fixed Inventories
Terry L. Friesz, Changhyun Kwon, Tae Il Kim +2
The problem of robust dynamic pricing of an abstract commodity, whose inventory is specified at an initial time but never subsequently replenished, originally studied by Perakis an…
Dynamic Congestion and Tolls with Mobile Source Emission
Ke Han, Terry L. Friesz, Hongcheng Liu +1
This paper proposes a dynamic congestion pricing model that takes into account mobile source emissions. We consider a tollable vehicular network where the users selfishly minimize…
