Graph-Regularized Synthetic Control for Stable Counterfactual Estimation under Donor Redundancy
Yanlin Zhang, Sungyong Chung, Alireza Talebpour
Synthetic control methods estimate counterfactual outcomes by weighting untreated donor units to match a treated unit before treatment. In recent applications, however, the donor p…

An Empirical Markov Chain Car-Following (MC-CF) Model
Sungyong Chung, Yanlin Zhang, Nachuan Li +2
Car-following behavior is fundamental to traffic flow theory, yet traditional models often fail to capture the stochasticity of naturalistic driving. This paper proposes an empiric…

Can the Waymo Open Motion Dataset Support Realistic Behavioral Modeling? A Validation Study with Naturalistic Trajectories
Yanlin Zhang, Sungyong Chung, Nachuan Li +4
The Waymo Open Motion Dataset (WOMD) has become a popular resource for data-driven modeling of autonomous vehicles (AVs) behavior. However, its validity for behavioral analysis rem…
