Exploring the drive-by sensing power of bus fleet through active scheduling
Dai Zhuang, Ke Han
Vehicle-based mobile sensing (a.k.a drive-by sensing) is an important means of surveying urban environment by leveraging the mobility of public or private transport vehicles. Buses…
Computing Dynamic User Equilibria on Large-Scale Networks: From Theory to Software Implementation
Ke Han, Gabriel Eve, Terry Friesz
Dynamic user equilibrium (DUE) is the most widely studied form of dynamic traffic assignment, in which road travelers engage in a non-cooperative Nash-like game with departure time…
Day-to-day dynamic traffic assignment model with variable message signs and endogenous user compliance
Ke Han, Margherita Lascia, Robin North +2
This paper proposes a dual-time-scale, day-to-day dynamic traffic assignment model that takes into account variable message signs (VMS) and its interactions with drivers' travel ch…
Nonlinear Decision Rule Approach for Real-Time Traffic Signal Control for Congestion and Emission Reductions
Junwoo Song, Simon Hu, Ke Han +1
We propose a real-time signal control framework based on a nonlinear decision rule (NDR), which defines a nonlinear mapping between network states and signal control parameters to…
Global optimization framework for real-time route guidance via variable message sign
Bai Liu, Ke Han, Jianming Hu
Variable message sign (VMS) is an effective traffic management tool for congestion mitigation. The VMS is primarily used as a means of providing factual travel information or genui…
Formulation, existence, and computation of boundedly rational dynamic user equilibrium with fixed or endogenous user tolerance
Ke Han, W. Y. Szeto, Terry L. Friesz
This paper analyzes simultaneous route-and-departure-time (SRDT) dynamic user equilibrium (DUE) that incorporates the notion of boundedly rational (BR) user behavior in the selecti…
