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…
Kriformer: A Novel Spatiotemporal Kriging Approach Based on Graph Transformers
Renbin Pan, Feng Xiao, Hegui Zhang +1
Accurately estimating data in sensor-less areas is crucial for understanding system dynamics, such as traffic state estimation and environmental monitoring. This study addresses ch…
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…
A vicious cycle along busy bus corridors and how to abate it
Minyu Shen, Weihua Gu, Michael J. Cassidy +2
We unveil that a previously-unreported vicious cycle can be created when bus queues form at curbside stops along a corridor. Buses caught in this cycle exhibit growing variation in…
