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…
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…
Optimal designs of heterogeneous grid transit networks
Wenbo Fan, Haoyang Mao, Li Zhen +1
A general Continuum Approximation (CA) model is proposed for optimizing transit network designs (TND) in grid cities under spatially heterogeneous demand. While conventional studie…
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…
Feeder bus service design under spatially heterogeneous demand
Li Zhen, Weihua Gu
In rapidly sprawling urban areas and booming intercity express rail networks, efficiently designed feeder bus systems are more essential than ever to transport passengers to and fr…
