Enforcing Priority in Schedule-based User Equilibrium Transit Assignment
Liyang Feng, Hanlin Sun, Yu Marco Nie +2
Denied boarding in congested transit systems induces queuing delays and departure-time shifts that can reshape passenger flows. Correctly modeling these responses in transit assign…
LLM-Guided Reinforcement Learning with Representative Agents for Traffic Modeling
Hanlin Sun, Jiayang Li
Large language models (LLMs) are increasingly used as behavioral proxies for self-interested travelers in agent-based traffic models. Although more flexible and generalizable than…
A Cardinality-Constrained Approach to Combinatorial Bilevel Congestion Pricing
Lei Guo, Jiayang Li, Yu Marco Nie +1
Combinatorial bilevel congestion pricing (CBCP), a variant of the mixed (continuous/discrete) network design problems, seeks to minimize the total travel time experienced by all tr…
A Day-to-Day Dynamical Approach to the Most Likely User Equilibrium Problem
Jiayang Li, Qianni Wang, Liyang Feng +2
The lack of a unique user equilibrium (UE) route flow in traffic assignment has posed a significant challenge to many transportation applications. The maximum-entropy principle, wh…
