Stability and Optimal Design of Adaptive Linear Bus Holding on Open Chains and Loops
Li Zhen, Weihua Gu, Miny Shen +2
Bus holding can suppress bunching, but its stability and performance depend on the feedback structure and on how the bus sequence is bounded. This paper develops a common analytica…
From Observation to Intervention: Mastering Bus Holding Control from Historical Uncontrolled Trajectories with Offline Reinforcement Learning
Minyu Shen, Xiaowen Bi, Weihua Gu +4
Bus operations are inherently unstable---buses initially dispatched at equal headways will inevitably end up bunching up. This issue exacerbates passenger waiting times, creates lo…
Group boarding for airplanes: benchmarking static policies and optimizing dynamic assignment with deep reinforcement learning
Minyu Shen, Weihua Gu, Junqi Ma +3
Improving boarding efficiency reduces airplane turnaround time and improves passenger experience. Airlines typically assign passengers to a few sequential boarding groups using sta…
Substitution or Complement? Uncovering the Interplay between Ride-hailing Services and Public Transit
Zhicheng Jin, Xiaotong Sun, Li Zhen +2
The literature on transportation network companies (TNCs), also known as ride-hailing services, has often characterized these service providers as predominantly substitutive to pub…
Optimal demand-responsive connector design: Comparing fully-flexible routing and semi-flexible routing strategies
Li Zhen, Weihua Gu
Demand-responsive connector (DRC) services are increasingly recognized for their convenience, comfort, and efficiency, offering seamless integrations between travelers' origins/des…
Cognitive Hierarchy in Day-to-day Network Flow Dynamics
Minyu Shen, Feng Xiao, Weihua Gu +1
When making route decisions, travelers may engage in a certain degree of reasoning about what the others will do in the upcoming day, rendering yesterday's shortest routes less att…
